I want to install three motion sensor activated flood lights outside. Total amperape for all three lights is 5 amps (non continous...also...assumming I use 6 100 watt bulbs). I plan on tapping in where the garage lights are. The garage lights are on the circuit with one of the 2 15 amp branch circuits servicing the living room. The total run for the three lights on a #14 cable run is 65 feet. Is the potential voltage drop going to be too great? I was thinking about maybe putting the lights on their own 15 amp circuit? Or, maybe running #12 throughout. Will #14 do? Thanks.
