What happens if you reverse hot and neutral wires on a light fixture?
When an outlet is wired in reverse, the hot wire is now on the supposed neutral side. So, if you were to plug in the same lamp as noted above, the lamp socket would have power even if the switch was off since the switch is only on the hot side.08-Dec-2020
How do you know if neutral and hot are reversed?
Measuring hot-neutral by itself does not tell you if they've been switched. You have to measure neutral-ground or hot-ground. If neutral-ground voltage is about 120 V and hot-ground is a few volts or less, then hot and neutral have been reversed.
What happens if you mix up hot and neutral wires?
This happens when the hot and neutral wires get flipped around at an outlet, or upstream from an outlet. Reversed polarity creates a potential shock hazard, but it's usually an easy repair. Any $5 electrical tester will alert you to this condition, assuming you have a properly grounded three-prong outlet.22-Jun-2021
Does it matter if live and neutral are reversed?
There are no polarities in AC, so live and neutral can get interchanged without any problem in AC circuit in appliances. However, when it comes to wiring in house, live and neutral should not be interchanged.
Is neutral wire white?
Here's a rundown of electrical wires: The black wire is the "hot" wire, it carries the electricity from the breaker panel into the switch or light source. The white wire is the "neutral" wire, it takes any unused electricity and current and sends it back to the breaker panel.29-Sept-2021
How do you tell which wire is hot and which is neutral?

Hard neutral and ground wires.
What happens if you mix red and black wires?
If the black and red are a hot and switchleg, then if connected to the black from the fixture it would mean the light is always on. If the black and red are 220V between them, then connecting them to the black from the fixture would burn up the fixture. You need to know which wire is 120V to neutral.
What happens if neutral and ground are reversed?
If you swap the two, then you have normal circuit current flowing on the ground wire and potential ground fault current flowing on the neutral wire. The latter is not as serious as the former. Contrary to popular belief, the neutral wire is not "safe" as it has current flowing on it under normal circuit operation.04-Jul-2017
How do you know if a receptacle is reversed?

Observe the pattern of the lights on the tester. ... Test several sockets in the building to assure the tester is operating properly.17-Jul-2017
Why do I have 50 volts on my neutral?
It's simple. Since switches have no neutrals, you're measuring voltage across the switch. The wire from the switch to the lamp is not a neutral, but connected to neutral via the light - a resistor, and that explains why you're getting only 50 volts. If you remove the lamp, it will read 0 volts.
What does it mean when an outlet is reversed?
If your outlet's polarity is reversed, it means that the neutral wire is connected to where the hot wire is supposed to be. This may not sound like a terrible thing, but it is.
