I am wiring my basement to be finished. I am putting 10 recessed lights in the ceiling. Can I put them on a 20 amp breaker circuit with 12 gauge wire? I have 200 amp service.
First find the amperage that each light will use. Add the number of lamps and if the total is under 20 amps it will be ok. 12 Ga. wire should suffice. Remember, halogen bulbs **** alot more amperage than incandescent.
This setup is fine, actually a bit of overkill depending on what size lamps you use. 10-75 watt lamps at 120 volts will draw 6.25 amps. If you switch them all together on one dimmer you will need a 1000 watt rated dimmer. Also a 75 watt halogen or a 75 watt incandescent bulb at 120 volts will each draw .62 amps.
