I wired (11) recessed 4" incandescent cans in series with #12AWG on a 20amp circuit. After wiring was complete I noticed there was a note on the can that said "maximum of (8) 12AWG through branch circuit conductors" The maximum load on this circuit is approximately 12 amps. What is the ramification of 11 vs 8 and if so what should I do. I want to control all lights from one dimmer.
