Electricity powers modern life, from businesses to homes and schools to medical facilities. Despite the momentum of the DIY homeowner movement, electrical work will always be in-demand. If you’re studying to become an electrician, here are four common mistakes you’ll want to avoid. 

4 Electrical Mistakes to Avoid 

1. Wrong Wire Size

The wrong size wire can make it difficult to make connections. Many people make the mistake of using wires without checking the amperage. Make sure the wire and outlet amperage are compatible. Another mistake is cutting wires too short, which can result in electrocution or electrical shorts. Wires should come out at least three inches from the electrical box. If you’ve cut a cord too short, you can add length as long as you use the correct wire terminators.

2. Outlet Overloading

It’s easy to accidentally overload an outlet, which can lead to circuit overloads or electrical fires. Avoid using multiple circuit extenders in the same outlet. You may also need to give some significant appliances their own circuit to avoid giving the channel more than its maximum electrical load. Remember, extension cords are not a permanent wiring solution. 

3. Leaving Wiring Unprotected

Exposed wire connections are a significant fire hazard, mainly if there are any flammable materials in the vicinity. Typically, you’ll need to splice wire in new connections. Make sure to cover it in a UL listed box after connecting. In addition to being a fire hazard, unprotected wiring and uncovered splices are code violations in most towns and municipalities, which could result in a fine.

4. Improper Box Installation

When installing an electrical box, ensure it is flush with the wall. If the box protrudes, people or objects may make contact with it, causing the connections to loosen or break. In addition to the risk of shorts and other malfunctions, there is a risk of electrocution.
