I'm installing a new circuit at my house and am thinking of adding a couple
of receptacles to it as well. The lighting load will be pretty minimal so
I'm sure from a load standpoint, I'd be fine to add the receptacles. What
worries me is the sheer number of "devices" allowed on a single circuit. I
have been looking through the NEC codebook furiously looking for an edict
such as "maximum of 7 devices per circuit" and can't find it. Is there such
a beast? If so, what's the NEC reference number and how many is it? I
appreciate any help you all can give.
You won't find a "device number" limit because there isn't one.
However, I have heard that you will have more luck with either more or
less than thirteen devices on a branch circuit.
Hope this helps,
Ok. I thought I was going crazy as I've heard there is a limit. I better
check my locality to see if they have a limit.
I've "heard" it is 10 so 7 lights and 2 recepts. should be fine but I'd
better look up the state code. Thanks much. I poured over the NEC book
looking for something with little luck. On the flip side, I'm slowly
starting to learn the entire book this way!
I was able to find the verbage in the state codes. I had been devoted to
finding it in the NEC with no luck, as you all know. Anyway, according to
the state code, it's 10 so I'm well within the parameters. Thanks for the
The NEC doesn't say how many devices on a branch circuit. But local
inspectors *always* have an opinion on how many is too much, so find out
what the local rules are. Probably something like 8 devices (duplex or
simplex doesn't matter) on a 15A circuit and 12 on a 20A circuit.
Again, this is local custom, not part of the electric code.
