How To Wire Electrical Disconnects

Electrical disconnects are neat devices. They are used to cut off the electrical power coming into your home in cases of emergency. They are typically installed on the outer part of your home or on the power line of the electrical service provider so that it can be accessed easily when needed.

  1. Have the correct type of electrical disconnect for your home. It is important to get the correct type of electrical disconnect breaker for this project, as one with an insufficient load capacity will just end up useless. Say your home is currently drawing 55 amperes of electricity, then the correct type of electrical disconnect breaker would be that of 60 amperes. If, say, you draw 25 amperes of electrical current, then getting an electrical disconnect breaker sized with 30 amperes should be enough.
  2. Always perform necessary safety measures before attempting to wire electrical disconnects. Electrical disconnect breakers are fed from hot wires. Hot wires, as their names suggest, have enormous amounts of live electrical currents running in them. These currents come directly from the electrical company's lines in your community. This being the case, then it is imperative that you switch off the main circuit breaker first to prevent a possibly deadly mistake. Best to have a voltage tester with you for this very purpose.
  3. Finally, wire the electrical disconnect breaker. Of course, aside from the correct type of electrical disconnect breaker, you will also need to use the correct gauge of wire. Wires that are too thin are prone to burning, so you may want to get a thicker gauged wire. Now, strip the insulation on the end of the wire with the use of a wire stripper tool. Make sure that you cut only up to a point needed, as too much exposed copper wire is dangerous. Also, avoid nicking or cutting the copper wires for the same reason. Now, the disconnect breaker has two terminals at the top of the unit. These will be used to connect the wires that are coming directly from the electrical company through the electrical meter wires. Meanwhile, the neutral wire should be hooked up to the terminal found at the side of the electrical disconnect breaker that is colored silver.

Bear in mind that wiring an electric disconnect breaker is a very dangerous task better left to a licensed professional electrician. Sure it may cost you extra, but the fact that you do not endanger your self, your family, or your property should make the extra costs an insignificant matter.
