Top Home Electrical Mistakes You Must Avoid

9 Top Home Electrical Mistakes You Must Avoid

September 25, 2021

Sometimes, DIY can be a great way to fix problems at home and add value to your investment. But that is not the same case with electrical projects. Amateur electrical projects are likely to bring more damages than good when not correctly done.
Like most people, when it comes to major electrical applications, they must hire qualified professionals. MR Glow can help you solve all the major electrical problems with the need for skilled professionals.

On the other hand, you can avoid mistakes when you opt to do some of the most manageable tasks. MR Glow recommends avoiding these electrical mistakes that may cause electrocution or fire hazards.

Let’s get started:

1. No GFCI Installed

Installing a GFCI outlet

This refers to the ground fault circuit interrupter. All electrical codes will need this GFCI outlet to help with shock protection in areas near the earth or water. These areas include the outdoors, bathrooms, and kitchens.

It is tricky to install a GFCI outlet. This is because it will involve two sets of terminals. So, when you do it without electrical skills, you can easily connect the terminals backward. And that will mean there is no more shock protection.

2. Improver Bonding/Grounding

Proper grounding will make your house’s electrical system safe. A ground wire will channel electrical surges harmlessly. In this process, it requires you to connect an electrically conductive system to the ground.

If you don’t have this protection, your house will be facing dangers because breakers won’t trip after short circuits. This is something all professional and competent electricians know. But as a homeowner, you may not know, therefore essential to contact MR Glow for such services.

3. Overloading Circuits

Circuit Overloading

Electrical professionals know they must test electric circuits to avoid overload. If you are an amateur, you will continue to add plugs without taking precautions. This will not be safe when it exceeds the standard rating. For example, the electrician must ensure the circuit is tested to avoid overloading before LED lighting installation.

4. Improper Junction Box

Installing a Proper Junction Box

We use a plastic or steel junction box when adding an electric outlet or light fixture. And where possible, anywhere there is an electrical connection, there should be a proper junction box.

Installing a junction box is a safety rule. You must install it because it prevents the spread of heat and sparks when there is a loose connection or short circuit. Remember that you can’t hide junction boxes or bury them in ceilings, floors, or walls. These boxes need to be on drywalls and a place you can easily access in case of electrical repairs.

5. Faulty Wire Connections

Faulty Wire Connections

The other common mistake most homeowners make is incorrect wire connections. This could be done with wrong conduit fittings or without a wire nut. And that means the connections aren’t watertight.

On the other hand, if the connections are metallic, that means they aren’t correctly bonded. That’s why loose connections continue to create shorts. Moreover, it will be tough to diagnose issues with your electrical connection.

6. Unsecured Outlets

Electrical outlets or receptacles should be attached firmly. When you install them poorly, they will move, resulting in electrical arcing – a fire hazard. However, electrical arcs and shorts in the outlet will damage all appliances plugged in.

7. Reversed Polarity

Reversed Polarity

Reversed polarity could be the most dangerous over other electrical mistakes. This is a problem that occurs after you reverse the “hot” with the neutral wire. When you do that, you will damage all your electronics and can lead to electric shock.
An experienced electrician will understand the proper way to switch the wires, fixtures, and outlets. That ensures nothing will happen.

8. Short Wires

Homeowners Make the Mistake of cutting wires short during residential wiring upgrades

When working on your electrical installations, then you need to equip yourself with enough wires. Most homeowners want to be like electricians and end up cutting wires short during residential wiring upgrades.

However, the right thing is leaving some inches that extend from the junction box. This will prevent experiencing poor connections that may be dangerous to your electrical system.

9. Using Wrong Wires

Homeowners Make the Mistake of Using Wrong Wires

There are different types of wires, and each type has a specific role. For example, when using a small gauge for your circuit’s amperage, use an indoor wire for outdoor applications or pull the wrong wire via a conduit.


Remember that some wiring connections require getting a permit. But not for all electrical activities. For example, when installing a new light fixture, you will not need a permit.

You can avoid all the hassles by hiring an electrician. MR Glow is the right company for electrical installations, maintenance, and repairs.
