Outlets and Switches

There are three way switches where you will find two travelers wire and the third one is the common wire. The most common trick, which is often applied, is that the electrician marks the common wire. It is helpful in sense that once it is marked then you can replace it with the new one where it is marked with dark bronze color. The installation of the common wire should be done with an identified screw terminal. The travelers wire do not create problem on fastening them with any other wires.

Wiring the outlet with correct polarity is very important. The white should be connected with the silver colored screw where as the black wire with the bronzed screw. The ground wire is connected with the green grounding screw. The outlets made for power and the switches are the place from where the air enters the house. This can simple be prevented by blocking the area.
