I am planning to tap into an existing light fixture so that the fan will be on
when the lights are on. There are a total of 6 lights that can be 60 watts
maximum each (or a total of 360 watts). The fan motor draws (I think) about 2
watts. I haven't bought the fan yet, but one I looked at that had a lower CFM
rating had a motor that is rated at 1.5 amps, so I am using 2 amps as a working
number for the fan.
If my math is right, the current draw of the lights is 360W/110 V or about 3.3
amps. The circuit breaker is 20 amps. Is this enough to account for the "in
rush" current of 6 light bulbs and one fan motor?? I'm pretty sure that it is,
but just want to make sure before I start cutting holes.
You should be able to get up to close to a total of 20 amps without a
problem. Standard circuit breakers allow a staring surge.
As it is your total is well below the safe working load. I don't like
to go over about 50-75% and you are well under that.
