Overloaded circuit?


I have some experience with electrical work but don't know about circuit loads. We are thinking about changing 2 rooms from switches powering outlets to ceiling fans. Here is what the current situation is:

20 amp circuit
10 outlets across 3 bedrooms and an outside light.

Thoughts?

You should be fine adding two ceiling fans to that 20A circuit.

Really? How do I calculate the current load? I do have a TV, LCD TV, Stereo, Computer, lights, etc on there now.

Add all the wattages from the different devices you have and subtract that from 2400, that tells you how much capacity you have left.

P=I*E
P=power in watts
I=amps
E=voltage

Do you have any electrical testers? If you happen to have an amprobe you can take off your panel cover, turn on your stuff on that circuit and go back to your panel and check the amperage running through that #12 wire coming from that 20A breaker. A standard ceiling fan draws between 10 and 100 watts with no light kit, that's less then 1 amp. 2 60 watt bulbs draws approx. 1 amp. 4 40 watt bulbs draws approx. 1 amp. You want to try and stay below around 16 or 17 amps tops.
