What happens if you wire a light switch wrong?
But here's the catch: If you connect the circuit wires to the wrong terminals on an outlet, the outlet will still work, but the polarity will be backward. When this happens, a lamp, for example, will have its bulb socket sleeve energized rather than the little tab inside the socket.
Does it matter how you wire a light switch?
In the case of a single-pole switch, these wires are interchangeable—it doesn't make any difference which wire is attached to which screw terminal. Inside the switch is a metal pathway that closes when the switch is in the ON position and opens to interrupt the flow of power when the switch is turned OFF.
Which color wire goes to the switch?
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 to connect a pigtail light to a breaker?
Test (again) for voltage on the bare wires. Assuming you find none, attach the pigtail light to the white and black wires (unless the black wire (or red wire) has white tape around it and there is no white wire, in which case attach the light to the black and red wires.) Turn the circuit breaker on and find the switch that controls the pigtail light. If the box does have a white wire coming into it, then turn the breaker off again , attach the pigtail light to the white and red wires, turn on the breaker and find the switch that controls the light again.
What is the black wire on a dimmer switch?
If it’s a single control dimmer then normally the white wire is your hot to the dimmer and the black is the return to power the light. The third wire should be the ground and likely will be a taped up version of the red wire. Now if it’s a three way dimmer you’ll have two travelers and a return wire plus the ground wire. When you’re hooking up to someone else’s work you have to trace out the leads to make sure of how they actually are used because not everyone does it the right way. Basically standard for any switch is white is hot to switch, black is return to
