Ground wires and Neutral wires are separate wires that are vitally important for the home electrical system. Tip #3: Before removing the switch, test each wire with a voltage tester. In North America, “Hot” and “Neutral” are the two wires suppying a 120V circuit. If it is in the vicinity of the supply voltage, one of the wires is the 'live' wire. However, and this is the big gotcha, if there is a break in the neutral line between where you are and where it is connected back to ground, it can be driven to the full line voltage. Without a continuous path back to the panel, and the neutral buss bar, the voltage has no place to go to complete the circuit. I am trying to install a ge smart digital timer, which I have. Two cables entering an outlet box indicate that the outlet … So you have a multimeter and you know the supply voltage in your area.
