If this is an extension cord or an appliance cord with molded-on ends, don't rely on the color! I have seen cords where the colors were not correct. If the manufacturer accidently uses the white for the hot, as long as both ends are the same, the cord will work. But if you cut into the cord, say, to put on a new end, and you use white for neutral, and the other end uses it for hot, someone willl get hurt. Best to use a continuity tester or multimeter to make sure which color is wired to the neutral prong. But yes, normally white (in the US) is used for neutral. IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB
SAFELY AND COMPETENTLY
REFER THIS WORK TO QUALIFIED PROFESSIONALS. If you do this work yourself, always turn off the power at the breaker box/fuse panel BEFORE you attempt to do any work AND always use a meter or voltage indicator
to insure the circuit is, in fact, de-energized.
Yes. But the white wire can also be a hot or switch leg if marked correctly. But for the most part white is netural.
White is neutral. Black is hot. Green is ground.
Canada and US - It is the neutral (potential to ground zero) return leg from the load back to the breaker panel.
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.
White.

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.
