I was thinking... according to code they indicate a maximum of 12 lights or outlets per circuit, or 80% of the load of 15 amp circuit... idk if I am acquiring puzzled below yet I am planning to usage slimled 9w 120v lights, 80% of the fill is 12 amps which is approx 1440 watts.. I am looking to put about 22 lights throughout entire basement with a few switches... each light according to my math would be 9w or 0.075 amps.. so technically I could put every one of these lights onto 1 circuit ? in Canada btw.

The codes have actually not really recorded up via the LED lights yet , I think you are fine as lengthy as these are light fixtures with a Led diode and also not an LED bulb that can be removed and replaced with a various form of bulb. Wait and also check out what Aaron and Wayne have to say on this.

Yeah in the NEC code for the US, there actually is no limit to the number of outallows (which describes both lights and receptacles) per branch circuit. You have to make the fill calculation yourself. I think Canada CSA code does have actually a limit on the number of outallows per branch circuit - it might be 12 as you say, Wayne would certainly recognize for certain. Either means, you shouldn"t assume that the lights will always be LED. I would still wire the circuits via the presumption that an old-fashioned 100W incadescent might be screwed in to the socket.Shannon"s best that the codes haven"t captured up through LEDs. I think it still follows a sort of worst-case scenario for high-wattage lights.

If your circuit has actually ONLY lighting, then you are not bound to the "12" devices ascendancy.As Shannon sassist, you need to calculate the wattage of the fixture, not the light. ie. if the fixture says maximum 100Watts ... that"s what you have to calculate.Many kind of of the newer LEDs (don"t accept typical bulbs) are rated incredibly low .... so you have the right to put A LOT of them on the circuit.If you put also 1 receptacle on this circuit ... you"re back at the 12 max tools thou !

With AFCIs being required now in many areas it make sense to store lighting circuits and receptacle circuits separated IMO.
Yes, agreed... I would always keep lighting sepaprice from receptacles. That means you have actually the liberty to have actually simply 2 or 3 lighting circuits in your whole home, and also run them in via low-price 14/2.I can view some time in the future where we might also run LED-exclusive lighting circuits via 16/2 or also 18/2, linked to a 10A or 5A breaker.

Most males are wiring that method now. Saves on an AFCI breaker ... likewise, smoke detectors have to be run off a lighting circuit. If that circuit has AFCI, you either should run a sepaprice circuit to it, or have actually the smoke det via battery backup.
I think smoke/CO detectors need to have their very own dedicated ordinary breaker through 14/3 run from the panel to the first detector and daisy-chained to each one down the line. You need that third red conductor for alarm interlink. The red wire continues to be stubbed in the breaker panel for future add-on alarm interlink.

I think they are normally put on a lighting circuit so that if the breaker trips for some reason you will be mindful of it sooner and obtain the trouble resolved . If they are on there own and also tripped the breaker for some stvariety factor you may not also realize it and also they will certainly not be activated.

Oh, that"s actually an extremely excellent suggest.Many modern ones will sound or display an alarm or something if they carry out not have AC power, and also I think all AC-wired ones have a 9V battery backup. But yeah, they take hardly any AC power at all so tapping them off a light circuit is actually not a bad principle and also really nudges the homeowner to take care of the circuit rather than simply ignoring it--as people tend to do.
