the thermostat has a black(line) wire to it, and a red wire going to it. the red wire then connects to the neutral wire. the black and red are like a leg switch.
The ribbed wire on a lamp cord is the neutral wire. On an extension cord there is no rib but the neutral wire is white in colour.
The white is neutral. The house does have a neutral wire even though it may be black. One of those black wires is the neutral and the other is the hot wire. You will have to determine which is hot and which is neutral. You can easily do this with a voltage tester. The wire that lights the tester is the hot. When you wire the light simply wire the hot to hot, and the white and green to the other wire.
The neutral wire and power wire are never connected together.
White.
In residential wiring the white wire is neutral on the 120 volt circuits. On a 3way circuit the red is the traveler and the white is neutral. On a 240 volt 3 wire connection the white & black are hot. On a 240 volt 4 wire connection the black and red are hot and the white is neutral.
Just cap the white wire off and fold it up in the back of the box, out of the way.
yes
Typical home wiring will have one hot wire, one neutral wire, and one ground wire per circuit. An open neutral would indicate that the neutral wire, usually white wire, is broken.
Red is hot Green is ground White is neutral
Connect to the circuit neutral wire which should also be white.
Because the white wire on a 120 volt circuit is the neutral wire that is connected to the silver screw on outlets and switches. It is connected to the neutral bar in the service panel.
