Halo Canister Light Installation
 
I am finishing my basement. How many canister lights can I run off a 15-amp circuit breaker using 14-2 G type wire? The canister calls for 75w R30 light bulbs. Thanks for any help.

You may install up to 1800 watts of lighting on a 15 amp circuit (14 gauge) for a residential application, and 1440 watts for a commercial application. If you're installing fixtures on this circuit with 75 watt lamps, you may install 24 fixtures in a dwelling, 19 fixtures for commercial.

In your other thread, you mentioned that you were using low voltage recessed cans. Are we talking about the same cans, or is this a different area?

Thanks for the reply. I am using Halo H71CAT Canisters.

Watts/Volts=Amps Amps x Volts=Watts


you are only supposed to load a circut by code 80% of its maximum(residential) so 80%=1440 watts =19cans.

I thought only in commercial can you have a "continuos load" application where you can use 100% of a circuts capability,in residention its 80%.Mainly because nothing will ever be "plugged in" or added to the commercial lighting circut,where in a residential lights and plugs are allowed to be on one circut so the circut is down graded since the load of the circut can constantly change by the hour/min.

No, it's the opposite. Almost nothing in a residential setting is considered a continuous load.
Almost everything in commercial is, or can be. Especially lighting.
