You are watching: How many can lights on a 20 amp circuit

The question: have the right to a 20 amp 12 AWG circuit because that receptacles that are general use receptacles in living locations be offered to supply strength to a light or two and the switches that control the light or lights? If power is simply as conveniently supplied by a bright circuit through room on it, then of course one would usage that. Yet if the most convenient supply for the lamp is this 20 amp 12 AWG circuit then deserve to it be used?

I have been said yes an ext times than no. But the no answers have some an ext detailed take on the worry as it comes to code.

Yes the can. Different areas have rule for fill on a circuit. As long as friend don"t have actually load concerns you room fine doing this. Lots of people don"t mix receptacles and also overhead bright to store the room lit if over there is a strength failure top top one yet this is no a tough rule and also is just great practice.

The wiring for the light needs to be 12 gauge, and also the light switch needs to be rated for 20 Amps. Can"t have 14 gauge cable or 15 amp switch almost everywhere on a circuit that is protected by a 20 Amp breaker.
