Basement pot lights on single breaker

Post by rao.manoj2004 » Fri Oct 26, 2018 7:19 pm

Hi Shannon/Aaron/Emtnut, I read on few of your previous comments that we can place more than 12 pot lights on single 15amp breaker but how much. Layout is attached.

30 LED pot lights with each 9W. Total load will be 270W.

Will it pass Ontario code :)

Strictly speaking, no. Even though you are using 9W lights and the total load if they were all on simultaneously would only be 270W, the CEC permits only up to twelve "outlets" (a term that includes light fixtures, receptacles, smoke alarms, etc).

I'm guessing you probably plan to use modern integrated LED fixtures, which would make it seem even more unreasonable that you couldn't wire up more than twelve fixtures. However, if you plan to install traditional pot lights with traditional screw-in sockets, you could then theoretically screw in thirty high-wattage halogen bulbs that could overload the circuit. So the code has not caught up yet with the new drastically-lower energy requirements of LED lighting systems, unfortunately.

So you'll need three 15-amp circuits for those, sorry to say. You could maybe wire two sets of 12 to two 15 amp breakers, and maybe the last 6 could use a pre-existing circuit in the house that has 6 or fewer things on it already (preferably lights).

The silver lining is that in Canada, at least you can use normal (cheap) breakers for dedicated lighting circuits. Here in the US, everything in the house must be on very expensive AFCI breakers now (with some few, very specific exceptions). Though we *would* be allowed to wire all 30 of those lights on one circuit as we have no number-of-outlets-per-circuit limit here.

Nutzy may have more to add; he knows CEC better as well as Ontario-specific stuff.

Thanks Aaron, :) I will go with 2 circuits. For extra 6 lights I will either share will receptacles or have one more circuits. Light wiring is clear. :D

Now only receptacles wiring need clarification in other post. Happy!! Halloween to all

You can have more than 12 outlets on a lighting circuit, but only if it is strictly lighting. If you wire up even 1 receptacle, then the 12 outlet limit is enforced.

For your fixtures, you don't add up the LED light (9W), you have to add up the max wattage listed on the fixtures.

Thanks Emtnut. I am using LED pot lights which comes with its own fixture as in attached photo. They are 9W (equival to 65W). No idea what should be max wattage for LED pot lights like I am using (slim).

That appears to be an integral unit (ie, you can't change the bulb). So yes, 9W per fixture. (double check the instructions, they should list the power draw, ie including the driver)

That's great news that there is no outlet limit on dedicated lighting circuits.

I think that part of our code still needs some updating, to account for LED lighting.
It's a start thou, anyways.
