Common Electrical System Mistakes And How To Prevent Them

It is crucial to have proper electrical connections in your home, office or places of business since failures or faults in the system pose a serious risk in terms of fire damage, electrocution and short circuits. Whether you are working in the electrical industry or tackling your own project, there are some common mistakes that need to be avoided. The consequences of improper wiring and other mistakes are possibly catastrophic, not just inconvenient.

Here are the top issues to watch for, and solutions for fixing them:

Wiring outside of electrical boxes

The main use of electrical boxes includes protecting wire connections against any accidental damage and also preventing electrical fire hazards by containing sparks and heat from loose connections and short circuits. Connecting these wires through an electrical junction box is essential for safeguarding them as well as property and people.

Using a “Too-Small” electrical box

If you are not using the right-sizes junction box, the wires inside it will be stuffed all together and also the box will be over-filled. When wiring is tightly crammed into a small box or space, the risk of short circuits is greater. This might be a potential fire hazard, which is why you should follow the minimum box sizes that are specified by the National Electrical Code.
Wires cut too short

If you cut the wiring too short, making some proper connections becomes more difficult and this poses a tremendous risk. Poor connections can cause overheating, short circuits and other electrical faults. It is safer to leave wires protruding about 3 inches or so from the box, which lets you easily move the wires around while making connections.

Unsecured cables and wires

When you are installing wires and cables secure them with a clamp to prevent strained connections and damage. Clamp selection depends on the type of electrical box you are using. Built-in cable clamps are not required for single plastic boxes, but cables should be stapled within 8 inches of the box. Internal clamps are needed for larger plastic boxes, and you’re required to staple cables within 12 inches of it. Use approved cable clamps for metal junction boxes, since wiring can be damaged by the sharp edges of the box.

Unsupported switches and outlets

Unsupported switches and outlets or loosely connected wires are a potential safety hazard, in addition to looking sloppy. They can move around or get pulled during use, damaging the connection between wires and terminals in them. As a result, the danger of arcing and overheating is higher, which can lead to fires and short circuits.
