Unless you are installing high wattage fixtures and lamps you should not have any concern.
If you want to figure the current draw, do the following.
1) add up all the light wattage (use lamp not fixture watts) on the single circuit.
2) divide the volts into the total wattage = amps.
From the breaker, I believe I have two ceiling lights (60W max each); one in the small bedroom/office, one in the bathroom. So 120W there.
I'm considering a 3-light bath fixture, such as this:
Which would make 3 additional 60W bulbs. Now I'm up to 300W, or about 2.5 amps (rough math).
Now, to throw a bit of complication in here.... like I mentioned, my office will be in the second bedroom. I don't entirely know how this is all wired yet, but I think its the same circuit. Which means a couple of PC's, total of roughly 600-900W including some audio and video hardware (work stuff). Which would be roughly 5-8 amps (rounded) if everything was on at once.
Also, I've pretty much gone entirely CFL and LED, with one exception in the living room because I had a 3-way bulb handy. So, my actual draw for these lights would likely be the CFL rating then, right? Or....
15W * 5 = 75W, roughly .65 amps - right?
Thanks for any help here
