Is this question asking about a neutral in a single-phase or a three-phase service?
Answer for a single-phase service
If it is in a single-phase service the neutral wire could run hot because it is overloaded and the circuit breaker has not tripped to cut off the current? That could happen if the ampacity of the breaker is either too big for the application or because the breaker itself has a fault.
Another cause could be that the neutral wire has been damaged or has become frayed so that it overheats when carrying the full amount of current - drawn by the appliance from the hot wire - back to the power station.
Answer for a three-phase service
If this question is asking about a three-phase Y-connected service then the neutral wire will run hot if there is an imbalance of currents drawn by the load from the 3 incoming service lines or one of the lines has become disconnected from the load.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

Why we don't get shock if we touch neutral wire..we need two wires to close circuit pH and n when circuit closes current will flow around the circuit and one wire gets shocked other not why?
We don't get shocked when we touch neutral and ground because neutral is grounded back at the distribution panel, so the effective voltage between neutral and ground is very low. It won't be zero, because there is current flowing on neutral, causing a voltage difference between the load and the distribution panel, but it is low enough, assuming there is no malfunction, to not cause a shock.In the case of touching hot and neutral, or hot and ground, you will get shocked because there is line voltage between hot and neutral, and because neutral and ground are connected together, there is also line voltage between hot and ground.Note, however, that connecting a load between hot and ground is a violation of the code and the intent of the design, because ground is not rated to carry current except in short term fault conditions - you must always connect a load between hot and neutral, or between hot and hot, as the case may be.
Can you turn off hot water heater but still have the breaker turned on Or will it burn the element?
no as it will burn out the element
When a dc motor is set in electrical neutral it will?
not run in either direction
Why ac motor brake coil burn out?
they get to hot/there is not enough cooling
Neutral and hot wired backwards?
For a US 3-prong plug, a smaller slot should be hot, the longer slot should be neutral, and the screw that holds the plate on should be ground. Cheap, inexpensive testers are available at hardware stores.
Will it hurt a clock which is meant to run on a 1.5 volt battery to be run by a 6 volt battery?
it can get really hot and burn the circuit
How do you determine hot to neutral?
How do you determine what? If you are asking how do you measure the voltage between Hot and Neutral, I suggest a voltmeter. If you are asking how do you differentiate between Hot and Neutral in home wiring, the Hot is Black and Neutral is White.
How do you heal your burn from a hot glue gun?
You treat it like any other burn--first you run it under cold water, and then after the burn is cool, put on some burn ointment (if you have any). Then, bandage the burn AND KISS IT BETTER! :)
Is monetary policy neutral in both the short run and the long run?
Monetary policy is not neutral in the short-run but neutral in the long-run. Besides, fiscal policy is not neutral in both short-run and long-run.
What wire do you use for 250 foot run?
1 # 10 hot 1 # 12 neutral 1#12 ground
What happens when you connect multiple speeds of a dc motor to power at the same time?
Most likely is that it will run erratically, run hot and may burn out.

What do you do if you get burn by water in the shower?
you can get a burn by the water if the water is to hot.
Will the engine start if the water pump fails on a 1996 Mazda Millenia?
It should. It will also run hot. It depends on how it fails. If it locks up, the belt may smoke and burn off. If it leaks, it will loose all the coolant and run hot.
What are the live and neutral wires in a ceiling light?
Black is hot and white is neutral.
Is the ridged wire neutral or hot?
If wired properly the ridged wire is the neutral.
Clear wiring which one will be hot?
Even though it is a clear wire, there will be a tracer of raised or indented rib on the wire to identify the neutral. You may have to run your thumbnail around the wire to feel it rather that see it. This ribbed identified wire will be the neutral leaving the other wire to be connected to the hot side of the circuit.
