Why do I have 3 hot wires?

The reason for multiple hot/neutral wires for one outlet is that the outlets are daisy-chained together. This means hot/neutral is only coming from one of the wires and it is being sent to the other wire.

Why does my light switch have 3 sets of wires?





A 3-way switch makes it easy to turn on a light fixture from two separate locations in the home. Wiring one is slightly different from wiring a single-pole switch. In a standard, single-pole switch, one light switch controls one light fixture—on/off.

How do you wire a light switch with 3 wires?

Quote from the video:
Quote from Youtube video: We run that into the wire connector which would sit within the switch box for switch. 1.. We then connect from this wire connector. And run the white wire to a wire connector in switch box.

Can you tie a neutral and hot wire together?

By connecting hot and neutral together, you’re closing the electrical path without a load. This results in very large current flow, and the breaker will trip.

Why are both black and white wires hot?

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.

How do you change a light switch with 3 black wires?





Quote from the video:
Quote from Youtube video: That's going to be connected to the dark screw on the new 3-way switch. In this old switch they use the push in terminals on the back of the switch.

Why does my ceiling light have 3 cables?

Your 3 reds in a connector are the permament lives. The three blacks are the neutrals. The single black will be your switch wire and should be tagged with a red/brown tape and the other red will be a switched live connection between the two lights. All the earths should be connected in a block.

What happens if you wire a 3 way switch wrong?

If you don’t correctly connect this wire, then your lights won’t work from more than one switch. Grounding the switch: You’ll also need to locate the ground wire and connect it to the switch too.

Can you have 3 sets of wires in one outlet?

Never connect more than one wire under a single screw terminal. It’s also not a good idea to direct-wire all three cables to the receptacle by utilizing both the screw terminals and the push-in terminals on the back of the device.

Why would a hot and neutral wire be connected?



Quote from the video:
Quote from Youtube video: So the hot wires carry the electrical current from the supplier. And over to the load. And the neutral wires carry the electric current from the load.

What happens if you switch neutral and hot wires?

The neutral wire is connected to ground at the breaker box, which is connected to physical ground nearby. If you switch the hot line and leave the neutral, then the whole device will be at neutral potential. That’s OK. If you switch the neutral, then the whole device will be at hot potential.

What happens if you touch two hot wires together?

You will receive a shock if you touch two wires at different voltages at the same time. You will receive a shock if you touch a live wire and are grounded at the same time. When a circuit, electrical component, or equipment is energized, a potential shock hazard is present.

What do you do with a neutral wire in a light switch?



Quote from the video:
Quote from Youtube video: Down here and we do have a neutral water we've got a white wire here. And this neutral wire that means that we can use any of these three light switches any of these three smart light switches.

What happens if black and white wires are reversed?

So, what happens with reversed polarity? In reversed polarity, both the hot wire and neutral wire get switched, causing the electric current to flow backward, entering the appliance through the neutral terminal instead of the hot terminal, which energizes the appliance even when off.

Does a neutral wire carry voltage?

Voltage is carried by the live conductor, but a neutral conductor is also necessary for two important functions: Serving as a zero voltage reference point.

Why does my neutral wire have power?

The reason that one of the power wires is named “neutral” is because it is connected directly to the building ground connection at the circuit breaker panel. Therefore it is connected directly to the grounding (third) wire.

Why do I have voltage on my neutral?



The voltage you are seeing on the neutral wire is conducting through that other load from the hot. Your voltage tester is detecting voltage without drawing current so the resistance of the other load is not seen. Try disconnecting/turning off all other loads on that circuit.

Why do I have 120 volts between neutral and ground?

If you have a neutral wire removed from the neutral bus bar in your panel it is possible to see 120VAC on that wire if the circuit breaker for that circuit is turned on and there is a load connected to the circuit and load device is also turned on.

Why do I have 80 volts on my neutral?

Check voltage across each conductors. If you read 80V between the hot and neutral, and read 120V between the hot and ground. You have a malfunctioning neutral. If you read 80V between hot and both the neutral and ground your problem is with the hot conductor.

Should there be continuity between hot and neutral?

If you are testing from one of the phase wires on the load side of the main breaker with it off to the neutral you will get a reading if any of the branch circuit breakers are on and connected to loads. Turn off all of the breakers and check again it should read no continuity. It’s a new house.
