The role of electrical contractors is critical in residential, commercial and industrial installations. Any electrical malpractice, which usually occurs when unqualified electricians carry out the wiring, upgrades or repairs, may lead to serious accidents, deaths or fires.

While equipment faults are unavoidable, how the system responds is critical as far as safety is concerned. Most electrical safety issues or risks arise due to equipment or wiring faults and malpractices.

In an installation with proper wiring and protection, the system will isolate the problem effectively and eliminate most of the potential risks. This works well as long as the electrician follows the best practices while complying with relevant codes and regulations.

Consideration when looking for electrical contractors

Beside qualifications, you will need to hire a licensed and insured electrical contractor with a good reputation, recommendations, and who is reliable and capable of delivering.

Find out the eligibility and credibility

Verify if the contractor meets all legal, professional and safety requirements. Hiring registered, insured and qualified electrical contractors ensures that you are protected in case anything goes wrong. Good references from past clients mean that the contractor is reliable and you can trust them with your project.

The main issues to pay attention to includes;

License and Insurance : Ensure the electrical contractors are licensed and insured. In addition, they should have the worker's compensation covers just in case there are injuries to the electricians.

Guarantee the work: Professional electrical contractors should have confidence in their work and will not have a problem giving a written guarantee.

Experience : The company and technicians should have the relevant experience carrying out similar projects. The experience requirements may vary depending on the scope and complexity of the work. However, it is advisable to settle on electrical contractors with at least 3 years of experience; complex jobs may require more years.

An electrical panel upgrade at the right time is necessary to protect your home from several electrical accidents. The board connects to various circuits, each of which has a circuit breaker that distributes power to all the electrical components through a building. The breaker trips and disconnects the electricity supply when there's a surge of current, posing the risk of overheating the lines and catching fires.

When Do You Need an Electrical Panel Upgrade?

The service panel is smart enough to automatically turn off the power supply when there's an overload or danger of overheating. Basically, it's the breaker that trips and cuts the connection. Neverheless, it can be fickle and sensitive to various factors, and there could be other factors determining when you need an electrical panel upgrade.

Defective Wiring

A major percentage of residential fires in the United States happened because of faulty wires. The risk is proportionate to the age of the building. You should upgrade the system if the cables do not meet the standard code or the insulation and other parts deteriorate. The warning signs include flickering lights, minor shock or tingling sensation upon touching an appliance, sparks in the sockets, discolored power outputs, and a burning smell near electronics.

Fuse Panel

Older homes built before 1960 have a few circuits that rely on fuses. These fuses can only handle 30, 50, 60, or 90 amps for the entire house. Such system will not work in a modern residence that needs something between 100 and 400 amps of power. The fuses will only increase the fire risk. You will need to replace them with circuit breakers.

A Remodeling or New Appliance

Your energy requirement increases when renovating the living place or purchasing a new appliance, such as an air conditioner or hot tub, that consumes a huge amount of power. If the system's amp capacity does not meet the electrical needs, the circuit breaker will trip frequently and cut the power connection.

Extension Cords and Power Strips

It's better to go for an electrical panel upgrade if you do not have adequate outputs for plugging all the electronics. Excessive use of additional strips and cords increases the risk of fire hazards. Contact an electrical contractor to install new outlets and circuits to safeguard your home from electrical accidents.

Unusual Behavior of the Electrical System

When it's related to electricity, anything different than normal is worrying. It's necessary to take immediate action when your electronics do not run at full power or when the service panel makes crackling sounds. Sometimes, the breakers do not trip if there's a loose connection within the circuit. So, even if there's no apparent problem, you should conduct a safety audit at regular intervals.

Conclusion

Do not wait for the sparks to fly! Do not make yourself regret later by delaying an electrical panel upgrade. In addition, electricity is not something to be a part of your DIY project; never try to change or install anything unless you are an electrician.

Smart wiring is the fundamental need of a house. If you want to have perfect wiring for your home, then you need to have an inspection of your current wiring from a professional Electrician. They would let you know of the precautions that you can take to save your home from electric risks which could be dangerous for your family members and kids. One can not predict about kids because they are always in a struggle to grab something new, or worse, put their fingers in electrical openings unintentionally. What should one do? Covering all the dangling electrical wires is not an ideal solution to this problem. Let's have a look at some Key guidelines for smart wiring.

Installing Enclosures

Enclosures will be the hub of your installation. You must have enough space after installation for future expansions. Each floor of your home should have a separate distribution board. So, instead of a single enclosure powering the whole house, it is recommended to install separated distribution boards dedicated to each floor.

Use Terminals

The purpose of terminal blocks is to keep your wiring clean, clean and tangle-free. Using terminal block does not create bird's nest of cables. You can make changes quickly at first glance. Also, you can keep an eye on your installation. You can directly manage your wire-to-wire connections using terminals.

Selection of Right Cables

Perfect wiring can only be realized when you have good quality cable. Your whole installation process relies on the quality of the cable. You must have detailed information regarding cables before installing them. Which type of cable is easier to work with? Which one is having more power capacity and efficient in lower voltage dropping? What kind of cable is required for each sensor point of your home? You should have answers to all such questions because these are going to help you out in having smart wiring for your home.

Use Finger Trunking

Finger trunking would help you to keep wires in an organized manner. You need to place this in between each DIN rail and make sure outer Trunking should be at least of double in width from the trunking between the rails.

Input and output wires labeling

Make sure that you have marked each entry and exit cable because if you want to do any further expansion in your home, then this categorization would be useful for you to change or expand. It would let you have easier access to your desired enclosure in future, and this will not be a tough nut to crack.

Electricians must be trained

If you are looking for perfect wiring in your home, then take help from skilled individuals who have PAT testing certification. You can not afford risk pertaining to electrical wiring. So make sure you are satisfied by the experience and cost of the professional.

Types of Non-Metal Conduit

Most of the non-metal conduit is made from a hard-wearing plastic like PVC. It is a practical choice in areas that can not accept metal, such as a hospital MRI room. Also, it is useful for encasing in concrete under a driveway, or areas that are often in contact with water. PVC conduit is not…

Most of the non-metal conduit is made from a hard-wearing plastic like PVC. It is a practical choice in areas that can not accept metal, such as a hospital MRI room. Also, it is useful for encasing in concrete under a driveway, or areas that are often in contact with water. PVC conduit is not only watertight, but is also able to stand up to long-term exposure to water without experiencing issues with corrosion or rust.

The preferred type of non-metal conduit is based on factors like the overall installation cost, corrosion resistance and mechanical protection. Here are a few of the most popular types of non-metal conduit:

Rigid non-metal conduit (RNC)

The rigid non-metal conduit is the most cost-effective option in the market and practical for those working on a tight budget. The fittings are easily attached together with a solvent which is a lot faster than the methods used to secure the separate pieces of metal conduit. Once the solvent is welded and cooled, the joint is certain to be watertight for the long-term. This type of conduit can be heated to make it more pliable and easily bent to fit the awkward spaces.

The standard size of this tubing is schedule 40 or 80. There is also the option to use different wall thicknesses and sizes. However, the thick tubing can start to get difficult to heat and bend, so is more practical for the straight routes.

Even though the RNC is a versatile option in a variety of situations, it does have the disadvantage of not being so effective at standing up to bumps or knocks compared to the metal alternatives. It is not a practical choice for grounding, so a special conductor is necessary. Also, when exposed to heat the plastic can expand and contract, so must be considered when planning the long runs.

Electrical Non-metallic Tubing (ENT)

The electrical non-metallic tubing is made of thin tubing like material that is flexible and easy bent to shape. But, the bend is not likely to stay permanently. This tubing is useful to get around obstacles without needing to weld or cut. Plus, it is quick to install with snap-in connections, which does mean it is not a practical choice for the moist environments. The preferred option for the mild damp areas is the liquid-tight flexible non-metallic conduit which is built with a proper seal to protect against water entry.

What Are the Different Metal Conduits?

Electrical conduit is a practical option to protect wiring from damage related to UV rays, abrasion and drywall screws. Plus, there are plenty of practical reasons to protect the wires and cables in and around the home.

Electrical conduit is a practical option to protect wiring from damage related to UV rays, abrasion and drywall screws. Plus, there are plenty of practical reasons to protect the wires and cables in and around the home. For instance, it makes future wiring changes safe and simpler, which can be sealed to give protection against explosion and fire hazards, and easier to work in the less inaccessible areas of the home.

Most of the metal conduit is manufactured in galvanized steel. But, there are also a few options available in aluminum. The types mostly used in residential applications include intermediate metal conduit (IMC), flexible metal conduit (FMC), electrical metallic tubing (EMT), and rigid metal conduit (RMC).

Rigid metal

The rigid metal conduit is the heaviest, stiffest and thickest option and relations on purpose-made tools to thread and bend the conduit. It is widely used at the electric-meter base to attach to the service-entrance mast. For most other areas of the home it is possible to use the less hard-wearing plastic or metal conduit. This conduit is mostly made of galvanized steel.

Flexible metal

The flexible metal conduit is made from aluminum and has a shape much like a long spiral. This type of conduit is only suited to use inside and not a practical choice for wet locations. It is often used on new cook tops and ovens. The conduit is flexible and used to protect the power source of the appliance. Also, it comes in a choice of two standard sizes of 1/2-inch diameter and 3/4-inch diameter. This conduit is quite easy to work with and is easily cut with a basic hacksaw.

Electrical metallic

The electrical metallic tubing is naturally quite thin and mostly available in galvanized steel. This is a low-cost option and is easy to install with plenty of cuts and bends without needing to rely on special tools. It is really useful to protect the wiring from physical damage inside or outside the home. Any installations that take place outside the home should be completed with fasteners, supports and fittings made of a corrosion-resistant material. A common use is with the meter base and protecting the ground wire. Also, it is worth using to protect exposed wires on the garage or basement walls.

Intermediate metal

The intermediate metal conduit is a further low-cost option and rated as a mid-range product. It is lighter and thinner than rigid metal, but a lot more durable and rigid compared to the electrical metallic tubing.

Types Of Conduit And Their Uses

Electrical conduits come in a wide range of styles to make it easy to find something that complements the particular installation. It can provide a high level of protection for the wiring in and around the home, such as the laundry, barn, garage, or territory areas. In addition to the different conduits, there is also…

Electrical conduits come in a wide range of styles to make it easy to find something that complements the particular installation. It can provide a high level of protection for the wiring in and around the home, such as the laundry, barn, garage, or territory areas. In addition to the different conduits, there is also the option to use a few types of wiring, such as THWN or THHN. The wiring can vary in size, so it is essential to have the type of conduit that is spacious enough to easily accept the chosen type of wire. Any conduit that is used for an outdoor application must be water tight and rated for exterior use.

Here are several of the most useful types of conduits to use in the home:

PVC conduit is a practical choice for the application that needs protection from wet environments. This conduit is easily directed in the right path using a wide range of attachments, such as elbows, couplings, connectors and fittings. But, it is essential to use a proper PVC glue to achieve a hold that is reliable and water tight. Also, this type of conduit is not conductive, so it is useful to add a ground wire at the relevant points.

The flexible metal conduit is preferred when there are plenty of tight bends in the installation. Some of the close quarter environments for this type of conduit include attic vents, can lights and water heaters.

EMT is a useful choice for concealing within the walls. It is easy to bend and lightweight, but is more likely to get damaged in the event of any contact. The more solid alternatives include rigid or IMC conduit.

The IMC conduit is a popular choice for those planning to work on an outdoor installation. It is galvanized and thick to easily stand up to areas where it could be damaged. This conduit is mostly used for exposed walls in outbuildings, garages or basements.

The most hard-wearing option is the rigid metal conduit. It is practical for the most extreme installations such as service feeder installations and under driveways. This type of conduit must be threaded at each end and is one of the most expensive options in the market.

Overall, it usually benefits to use a rigid type of conduit when possible because this has the ability to give the best and strongest protection against damage. This is especially important for the outside jobs when there is the risk of storm damage, falling branches, or similar issues.

Plus, it is easy to protect against corrosion by applying the right protecting paint. It is one of the thickest and heaviest in weight to make it a practical choice for the most difficult environments.

Metallic

Metallic tubing (also referred to as EMT) is mostly made of aluminum or steel. It is more cost-effective and lighter than the alternatives in galvanized steel. This conduit is flexible to give more freedom in installation and a popular choice with industrial and commercial buildings. Also, the outer surface is naturally corrosion resistance, so there is not any need to provide a special coating.

Electrical non-metallic

The electrical non-metallic tubing is made of a thin, corrugated type material that is flame retardant and moisture-resistant. It has high flexible properties and is easily shaped by hand to fit the tight or awkward spaces. This is a perfect type of conduit for those in search of low labor costs and fast installation.

Flexible Metallic

The standard flexible metallic conduit is a practical choice for the dry environments and is simply a hollow tube with space for the electrical wires to pass through. There is also a liquid-tight flexible conduit in metal that has a waterproof coating. This is more practical for the damp locations and can be embedded in concrete or buried in other areas.

PVC

PVC is the most common type of conduit used for residential and commercial installations. It is a very affordable option and the PVC pipes are thick to give a useful amount of protection. PVC is naturally able to avoid issues with corrosion and resists moisture.

Aluminum Electrical

The aluminum conduit is a rigid option for the commercial applications and a practical option for areas that are prone to high moisture content. It is a useful choice to use in concrete slabs or walls, but can not be buried in concrete because the alkali content in the cement can cause a negative reaction.

The fuse is a practical part of an electrical device because it helps to protect the circuit and avoid issues with overloads. There are plenty of different fuses in the market, but most include a non combustible material to house a low-resistance metallic wire. In the event of a mismatched load, over current or short-circuit, the thin wire is designed to instantly melt in view of the much higher current flow and heat generation.

Here are a few of the most popular types of fuses:

Current limiting

The current-limiting fuse is a type of high interrupting fuse that is designed to safety break at 600 AC V and up to 300,000 amperes. A great benefit of this fuse is the speed that it is capable to operate which helps to protect the electrical devices from potential damage.

Resettable

The resettable fuse has a built-in polymeric positive temperature coefficient (PPTC) thermistor to protect a circuit in the event of an over current situation. This type of self-resetting fuses is reusable and will revert back to low resistance once its device has cooled. This fuse is a popular choice for nuclear or aerospace applications where it would be very difficult to install a replacement. Also, they feature in a PC motherboard to protect it against permanent damage in the event of a short keyboard or mouse.

Thermal

The thermal fuse is a popular choice for a wide range of consumer electronics such as hair dryers and coffee machines. This fuse has a spring contact mechanism held close by a fusible, temperature-sensitive alloy. In the event of a sudden increase in temperature, the alloy will quickly melt and break contact with the circuit. This is useful in a hair dryer when the heating element is blocked to avoid the risk of fire. The thermal fuse is one time use and must be replaced in the event of being blown.

High-voltage

The high-voltage fuse is the right choice for a powered system that runs up to 115,000 AC volts. It is used in small power transformers or for electricity metering. For instance, it can feature in a distribution system to give appropriate protection to a transformer that is serving multiple properties. This is a large and expensive fuse that can be rebuilt in the event that it is blown. They are built using predictable and stable elements, such as tin, copper and silver. Also, certain fuses contain gas-evolving substances, which are only practical for outdoor use.

I was talking with my daughter the other day, and I told her a story which could have gone much worse. I was cleaning my house when I found a one-inch piece of charcoal burnt into one of my couch cushions! It came from my fireplace from a piece of wood that popped from there to the couch. While all that little chunk of ember did was burn a hole in my furniture, my house could have gone up in flames! We are both thanking our stars that all I had to do was turn the couch cushion around!

As we age, though, lighting our home with a fireplace is not the only concern we have. A lot of falls are caused by bad lighting and not being able to see where we're going. Whether it's changing your light bulbs, or changing the way and times you keep your house lit, here are a few steps to fall-proof your home with lighting:

1) Are Your Lights Bright Enough, and Do Your Walls Reflect That?

Can you see what's in front of you? With dim lights, the answer may be no. According to the Lighting Research Institute, an older retina needs lights that are 2 to 3 times brighter than those comfortable for younger people. Your walls can help increase brightness – have your walls painted and finished with bright or light colors that will reflect the light and brighten the room! The best kind of light is fluorescent lights. They not only help you see better, they help you distinguish between colors better and are environment friendly!

2) Are Your Lights Covered?

This may seem like a contradiction given the above, but the goal here is not to din the lights, but to prevent glare. Glare happens when the light reflects off too bright and shiny surfaces, causing bright spots of light that can impair your vision. Lights should be covered with light lamp shades or opaque covers and positioned away from shiny surfaces such as linoleum floors or granite countertops.

3) Are Your Floors Clean and Free of Any Trip Hazards?

As a fail-safe, make sure your floor is clear of falling hazards such as loose rugs, articles on the floor such as shoes, clothing, and short furniture. Even with proper lighting, these articles can be missed and lead to a fall. Also, consider contrasting the furniture with the walls (darker furniture) so they are easier to see.

4) Is Your Lighting Safe and Up To Date?

Going back to the fireplace, is your lighting safe? While a fireplace is not bright enough to light your home on its own, if you have one, do you have a safety screen up that will keep hot debris from getting on to furniture? Also, consider getting a gas fireplace with an on / off switch on the wall. That way, you will not have to bend over to start it or stock it with kindling and wood for traditional fireplaces.

Another Point of Consideration

Also, if you live in an older house, it may be a good idea to make sure the wiring is up to date. Make an appointment with an electrician to see if there are any fire hazards as well as making sure your house is bright enough and up to date to prevent falls! If you live in an older house, the outlets may not be able to handle the amount of voltage your new lighting appliances require. The only way to know, is to ask the professionals. You should not have to sacrifice the lighting and safety of your house just because you have old outlets!

A Homeowner’s Guide to Surge Suppression

Most people know that surge suppression protects sensitive electronics, but they would struggle to explain why it's necessary.

Most people know that surge suppression protects sensitive electronics, but they would struggle to explain why it's necessary. The current in a power grid naturally fluctuates a little, but huge spikes can be caused by lightning strikes. The circuitry in computers and other electronic devices are not built to handle extremely high voltages, and many of these products can be damaged by less than a second of extremely high voltage.

The Whole House Needs Protection

You'll need a lot more than a power strip to solve this problem. When you purchase an old home, it's important to have an experienced electrician inspect the wiring. Older homes are more likely to have adequate surge suppression, and dangerous voltage can come through virtually any wire, even telephone lines. After a lightning strike or another spike in the electrical grid, a protective system can divert excess voltage directly to the ground line. This kind of system is hard-wired into the house's service panel. Separate boxes can be installed for the phone and cable lines. In the era before cordless phones, holding the receiver during an electrical storm could be dangerous. Now, the larger concern is expensive devices like televisions and entertainment systems that might plug directly into a cable line.

Not All Power Strips Are Equal

Many of the cheapest power strips offer little or no protection against voltage spikes. They function essentially as extension cords that provide multiple outlets. Attentive consumers can find strips that do offer surge suppression, and some products even include jacks for phone and cable lines. As much as 15 percent of the unwanted voltage can get past the systems designed for entire homes, so it is important to still use protection on critical outlets near computers and entertainment centers.

Outages Also Cause Damage

Early users of personal computers were frequently warned of the damage caused by improperly shutting down their desks. Modern devices are designed to be more resilient when it comes to hard shutdowns, but a loss of power can still mean that work and other information is lost. An uninterruptible power supply (or UPS) is commonly recommended for computers, especially if you use a desktop PC for work. The battery incorporated into the device allows you to continue working during a short outage. More importantly, it gives you an opportunity to save progress. Most UPS products will use audible warnings or flashing lights to warn when the battery supply of power is low, allowing the user to properly and securely shut down the system. It is a good idea to unplug important devices during an outage because there may be a spike when the power returns.

These are just three of the key principles for managing the circuitry in a home. An experienced and licensed electrician can provide far more information about specific recommendations for your home. Some local grids are more reliable than others, but even a single outage or spike can cause significant damage. Shorted electronics can also lead to electrical fires that endanger the entire property. As a homeowner, it's always best to take reasonable precautions.

If lighting strikes a building, the electricity can cause a fire or can electrocute anyone who is nearby. But how can people protect them against one of the strongest and most unpredictable forces of nature? A lighting rod, also called a finial or air terminal, is a simple device that can protect all sorts of structures from electrical damage during a storm.

What Is It?

A finial is a metal rod that is mounted on top of a building or any other structure that needs to be protected from lighting, including bridges and ships. They can come in many forms along just straight rods, including rounded, pointed, or flat. They may be hollow or solid, and can even be made up of bristles, similar to a brush. Whatever form they come in, the metal spikes draw the electrical charge from a lightning strike, diverting the energy by transferring it to the ground through a wire connected to the device.

How Does It Work?

A simple lighting rod depends on three integral pieces – the metal rod, a wire, and a grounded absorber. When the finial is stuck, the electricity typically travels along the conductive wire, which is made up of a conductive material, and into a ground. The ground, also called an earth, is another piece of metal that is driven into the actual ground. From here the electricity dispers without causing damage to the structure. However, if homeowners suspect that their rod has been hit, they should still be sure to examine their home for any damage since a great deal of energy has been transferred.

Buildings that need extra protection may use a system made up of several of these devices that have been networked together through bonding conductors, connectors, and supports. The conductors are then connected to the ground in the most direct path, ensuring that the electricity is sent away from the building as quickly as possible.

History of the Lightning Rod

Benjamin Franklin, the United States' pioneer of electricity, designed the earliest lightning rod. He first came up with the concept in 1749, and over the next decade, he developed the idea into a usable household product. In fact, early incarnations of this device were known as a Franklin rod. There is some evidence that the first lightning rod was used on a tower in Russia in the early 18th century, before Benjamin Franklin's invention, but there is no concrete proof that this was the intent of the design.

After the use of the finial had become common, people in the 19th Century began to use them as decorative accents for homes. They were often decorated with glass balls, which were both attractive and served to alert occupants that a strike had occurred, as the balls would shatter when hit.

Thanks to this ingenious device, people can now rest comfortably during an electrical storm and enjoy the awesome display of nature's power without worrying that they are in danger.
