What happens if you switch black and red 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 do I do with the red wire?

Red electrical wires are the secondary live wires in 220-volt circuits and are commonly found in a sheathed, multi-conductor cable. These wires are typically used for switch wiring as well as the interconnection between smoke detectors hard-wired into the power system.Apr 8, 2019

What does red wire connect to?

Red. Red electrical wire indicates the secondary live wires in a 220-volt circuit, used in some types of switch legs and in the interconnection between smoke detectors that are hard-wired into the power system. You can connect a red wire to another red wire or to a black wire.

Can I connect red wire to white?

I am reluctant to answer this but in residential 120VAC wiring in the US, the answer would be no. White is neutral. Red is either the other phase of the 240 volt mains into your house, or sometimes, inside the house, after the breaker panel, white is neutral, black is 120, and green is ground.

Why does my outlet have a red wire?

If you see a red wire spliced together with a black one in a 120-volt outlet, it’s probably because the outlet is powered by a wall switch. Certain switch loop configurations require a three-conductor wire — the extra wire is needed to complete the circuit at the switch.Sep 12, 2018

What is the red wire coming out of my ceiling?
