Which is live blue or white?

All this said,remember to always test the wires with a meter or voltage sensing device prior to making any connections if you are not 100% sure. The blue wire will be the live one but always don't assume it may depend with the connection so normally test first to be sure or else …

What is the blue wire for?

Blue wires are used as travelers, usually on three- or four-way switches (controlling a light from multiple locations) or as switch legs for things such as fans or lights. Yellow wires are almost always used as switch legs for outlets, fans, or lights.

Can I use blue wire for hot?

“Blue and yellow wires are sometimes used as hot wires,” Dawson says. Specifically, blue and yellow electrical wires are often used as “traveler wires” for transferring power between three- or four-way switches.

Can I use blue wire as neutral?

The blue wire, also referred to as the neutral wire, has the function of transferring electricity away from the appliance. The brown wire, otherwise known as the live wire, transfers electricity to the appliance. The combination of these wires is referred to as a circuit.

What are white wires used for?

The white wire is the "neutral" wire, it takes any unused electricity and current and sends it back to the breaker panel.

Does the blue wire go to white or black?

Connect the blue wires together or the blue wire to the black wire for lights. Follow the same step for ceiling fans without lights. This will allow you to add a light kit later on without having to rewire the fan. Tuck the wires back into the box.

Can a white wire be hot?

White Wire Labeled as Hot

Sometimes a white wire is used as a hot wire—not a neutral—in a switch leg, or switch loop, between a switch and a light fixture. ... The power is fed up to the light fixture, so there is a hot, neutral, and ground wire already there.

What do different color electrical wires mean?

Electrical wiring comes in one of several colors: Black Wires – when you see a black wire, always assume it's live. ... Blue Wires – always assume they are live if you have power. Blue wires are also fed through a conduit, usually bringing power to three or four-way switches. Green Wires – green wires are grounding wires.

What happens if you connect white wire to black wire?

If you see both sides connected together, it means it's a switch loop. The white wire that's connected to the black wire carries power to the switch. And the black wire that's in the same cable carries back that switched power to the outlet. But keep in mind what you should do when the wires are connected.
