Do-It-Yourself Electrical Mistakes

Connecting Wires Outside Electrical Boxes

You cannot just pull wires and connect them willy-nilly. You can probably imagine the disaster when rainwater or even plumbing leaks get acquainted with exposed wires. Junction boxes, also called J boxes, protect wires from the elements and accidental damage. They also contain sparks and heats from potential loose connections and short circuits. Don’t worry if you have connections which are not in an electrical box. It’s easy to install a box and reconnect wires inside of it.

Cutting Wires Too Short

Short wires make connecting them difficult. Even if you do manage to connect the short wires, the connection will likely be poor and dangerous. You should leave at least 3 inches of wire protruding from the box. Don’t worry if you run into short wires, though. The fix is simply a matter of adding six-inch extensions onto the existing wires. You can purchase these extensions at your local hardware store.

Failing to Protect Plastic-Sheathed Cables

The plastic sheath covering the wires and cables offer some protective properties, but that protection is slim. It is way too easy to damage this plastic sheathe and expose wires. So, we recommend you use metal conduit or some sort of 1.5-inch board to protect exposed plastic-sheathed cables. In fact, the national electric code requires these cables to be protected in many areas.

Loose Switches and Outlets

Switches and outlets that are not secured to the wall look bad, but they are also dangerous. These loose switches and outlets can move around and cause wires to loosen from the terminals. If these loosened wires overheat, then you might be exposed to a fire hazard. Shimmy under the screws to create a tight connection. You can find special spacers or washers at your local hardware store.

Three-Slot Outlet Without a Ground Wire

It’s tempting to replace two-slot outlets with more practical three-slot outlets, but this is not a matter of replacing the outlet. You should only install a three-slot outlet if you are sure there is a ground wire available. You can purchase a tester to see if your outlet is grounded. If there is no ground wire, then stick with a two-slot outlet.
