Electrical Mistakes That Homeowners Usually End Up Making

Updated: Jun 5, 2021

There are a lot of television shows that involve DIY-ing home improvement projects. One of the features these shows have in common is the tendency to make light of electrical repairs as well as improvements.

While it’s recommended to leave electrical work to the experts, this doesn’t mean that the standard homeowner cannot take on this project at all. That said, conducting any type of electric repair service should be done correctly. Unnecessary shortcuts can lead to problems such as short circuits, electrocution, and worst of all, fires.

What Are the Electrical Mistakes That Homeowners Usually End Up Making?

– Junction Box Installation Behind Drywall

When a junction box is installed, that doesn’t automatically mean safety is guaranteed. The box needs to be flush with the drywall and fitted properly. The last thing anyone would want is for wood and other combustible materials to get exposed to possible sparks. Thankfully, there’s a way to correct a junction box being too far in a wall: a box extension.

– No Junction Box at All

While it’s sometimes referred to as a connection box or electrical box, it all means the same thing: it’s a device that keeps electrical connections protected. It’s also able to contain heat or sparks in situations wherein a short circuit happens. The box is rather inexpensive, which makes it literally a small price to pay for the safety of the home’s occupants.

– No Support for the Switch or Receptacle

Aside from the obvious aesthetic issue since loose switches and receptacles look unkempt, these are also entirely unsafe. They move around and lead wires to be loose from the arc and terminals. Luckily, all it takes is to buy and add some spacers for the issue to be resolved.

– Overfilled Junction Box

There is no good reason for a lot of wires to be crammed into a junction box. There’s usually an approved volume stamped on plastic junction boxes. Steel, on the other hand, may need manual calculations: multiply depth, height, and width of the interior.

– Wires Being Cut Too Short

It’s necessary to have wires that can extend at least 3-6 inches from where it’s connected in the junction box. Therefore, it’s key that this much slack is constantly available. The way to tell that wires are at the right length is if they can be stripped properly, securely connected, and folded over within the box itself. No worries if they’ve been cut too short, as a simple splice and extension addition should solve everything. This is particularly important to take note of because when wires are too short, they pose a hazard due to poor connections.


Electrical repairs are usually best left to professionals, but there are certainly some that can be done by the homeowner. Unlike popular misconceptions from several DIY shows, there’s nothing light about electrical repairs or improvement. Many popular mistakes made when it comes to home electricals include not having a junction box at all, failing to support a switch or receptacle, and overfilling the junction box. If, along the way, you decide to just leave it to the experts, it doesn’t hurt to ask help from an electrical contractor.
