Too much on one Circuit?
Hi, I'm thinking about installing two ceiling fans (w/o lights) on a front porch. I'm thinking about tying in to a gang of switches that control: 1)two indoor lamps (CFL bulbs), 2)an indoor ceiling fan (w/o light) and 3)two porch lights (each 40w I believe). I don't remember for sure if the breaker is a 15 or 20 amp. Does this sound like too much on one circuit?

If that's all you have on that circuit (171 watts) you should be fine adding another 130 watts. Even a 15 amp circuit can supply 1440 watt continuously.

Thanks you for the response. For future reference, I'd like to see if I am figuring this out correctly. I see that a ceiling fan can consume anywhere from 10-80watts (so I'll use 50). A 75w equivalent CFL uses about 18-20w (I'll use 20), and then two 40w incandescent bulbs (80w). Totaling: 50 + 40 + 80 = +/-170w. The 15 amp circuit can provide: 110v x 15a = 1800w. Taking 80% of this (recommended load on a circuit) = 1440w. Right?
