1. This is normal if your neutral conductor or a busbar is under size wherein the source is a 3 phase + N + E. 2. Most pre-fabricated 3 phase panelboards have a neutral busbar size just equivalent to phase busbars . 3. When your loads are mostly or all 1 phase in a 3 phase panelboard -- the Neutral Busbar is overloaded and heating will occur or melting. 4. When planning or designing this is given attention in specifying or computing details prior to manufacturing or fabrication of panelboards. 5. If the heating occurs in a conductor -- please check loose connections either side of terminations or you may trace that particular length of neutral cable if it's used (tapped) for other loads.

Why are the live wire and neutral wire never joined together?
An electrical circuit forms a loop. The "live" or hot wire supplies the voltage, which is returned on the neutral. If the hot wire and neutral wire were connected together without a load between them, the circuit would be short out and trip the circuit's protection device.
Why neutral wire doesn't give electric shock?
The neutral wire doesn't give an electric shock because it is the same potential as ground. That being said if you come in contact with the "hot" wire and the neutral or ground wire, you become the load and will receive a substantial shock.
Why is it always connected in the phase or line wire to the switch and not the neutral wire?
because its much safer to switch the hot wire then the neutral wire because if you are working on a light fixture for example and the switch is off if you ground yourself out to the neutral you become the load or return. a neutral shock can me more dangerous at times
What to do with the white wire in track light with black green and white wires if the house does not have a white one?
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.
Which is the Hot wire and which is the Neutral wire if the wires you see are a Brown a Blue and a Yellow Green wire?
Brown = Hot Blue = Neutral Yellow/Green = Ground
What does an open neutral mean?
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.
Is the ridged wire neutral or hot?
If wired properly the ridged wire is the neutral.

Which of the two wires is hot which is neutral?
If this is a home wiring question and the wires are black and white then black is Hot and white is Neutral. If you also have a red wire, it is the other hot wire, and either the black or the red wire to the white one would be 120 volts, and red to black would be 240 volts.
Which is the Hot wire and which is the Neutral wire if the wires you see are a Brown a Blue and a Yellow Green wire?
Brown = Hot Blue = Neutral Yellow/Green = Ground
What happens if neutral and hot touch each other?
If a "hot" wire contacts the "neutral" or ground wire, electrical current flows to the ground.
A light switch has three wire colors red and white and green which is the hot wire and which is the neutral?
Red is hot Green is ground White is neutral
Which is the Hot wire and which is the Neutral wire if the wires you see are a Black a Red and a Yellow wire?
Black red and yellow is three-phase. there is no neutral.
Why does ac power have a hot wire and neutral wire?
so you don't get shocked
