In order to have power in your home to operate the heat and your appliances, you do need to have electrical installation and wiring. This is one part of the construction phase that has to be done by a qualified professional. You should never attempt to install anything connected with the electricity if you do not have the proper training.
Some of the basic principles of electrical work are:
* Never start working with electricity until the power supply to the home has been shut off.
* Wires of the same color connect to each other.
* When installing receptacle boxes, you push the bare end of the wire into spring grip holes. The boxes have labels to tell you what color wires go into each hole.
* The black wires in the cables are used for connecting switches.
* The wiring used in homes is Number 12 or 14 gauge wiring.
* For any extended wiring circuit, always use the same size cable for the continuation.
When you are connected new wiring to the existing wiring in the home, you should always do so in the last outlet on the run of cable. You can find the last outlet by removing the plate to see how many wires are connected in the outlet. The last one will have wires connected to only two of the terminal screws. The two remaining terminal screws will be the starting point for the new writing. You do have to check to see which gauge cable was used and you have to continue with this.
Unless the junction box is full, you can also attach new wiring to this box. Trace the cable back to see what voltage is on it so that you won't connect a 120- voltage to one that has 240- voltage. Locate the white wires in the box and attaché the new white wires at this point.
