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 I connect red and black wires together?
These wires are typically used for switch wiring as well as the interconnection between smoke detectors hard-wired into the power system. You can link two red wires together, or you can link a red wire to a black wire. Since red wires conduct current, they are considered hot.

What happens if you mix up hot and neutral wires?
This happens when the hot and neutral wires get flipped around at an outlet, or upstream from an outlet. Reversed polarity creates a potential shock hazard, but it’s usually an easy repair. Any $5 electrical tester will alert you to this condition, assuming you have a properly grounded three-prong outlet.
What happens if you wire a light fixture backwards?
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.
Which wire is L and which wire is n?

| Line, 3-phase | L2 | red |
Which wire is hot if both are black?

What does an N on a wire stand for?
The N and L are for neutral and load. You should have three wires in your AC line. Load, ground, and neutral. The black wire is Load or Hot, the white wire is neutral, and the green wire is Ground if your wires are colorcoded for the US.
