Does it matter if I wire a light backwards?

Tip. The fixture still works if you reverse the wires, but the socket sleeve will be hot, and anyone who touches it while changing a bulb can get a shock. When wired correctly, the socket sleeve is neutral and only the small metal tab at the base of the socket is hot.

What happens if you switch hot and neutral wires?

In North America, switching the hot and neutral wires on the AC breaker will cause a potential shock hazard with the polarized electrical outlets and lighting fixtures connected to that breaker. At the breaker, neutrals are supposed to be connected to earth ground. Hopefully you would blow a breaker.

Does a light switch break the hot or neutral?

The switch should be on the hot, not the neutral, wire. It’s a safety thing. A switch will work on the hot or the neutral, but if you switch the neutral, the light fixture is still electrically live even with the switch turned off.

Can a switch be wired backwards on a circuit?

Normal switches only have two poles and cannot be wired backwards. The black wire is the hot wire and a black wires go on each pole. The purpose of a switch is to make and break the hot wire. The white wire is the neutral and is grounded in the breaker box and runs to the load and not through the switch.

What happens if you wire a light switch wrong?

If a light switch is wired up wrongly, a short circuit may takes place if you give phase and neutral to the switch terminals. Always connect neutral wire to the one terminal of the light and phase to the one terminal of the switch and off wire to the other terminal of the switch to the light other terminal.

What happens if you bypass a light switch?

A light switch only interrupts the hot side and the neutral wire bypasses the switch. Amateurs will sometimes reverse this. The result is that the light will appear to work normally (making the error hard to detect). But what that means is the light is ALWAYS energized and only the return at the switch is toggled on or off.

Can I replace the Live Wire in a light switch?

You only have “live wire” going through light switch. The purpose is to make or break circuit. The switch has two poles one for incoming supply line and other leading up to light fixture. You can swap them if you want. The light will work just fine. But 1) you will have live wire directly connected to lamp so that’s a danger while repairs.
