To get back to the OP, is there a limit for number of 20a receptacles on commercial 20a branch circuits? e/m.
Yes, there is. 180va per yoke. Window candles were just more interesting.Energy-Miser said:To get back to the OP, is there a limit for number of 20a receptacles on commercial 20a branch circuits? e/m.
Thanks Marc, but that is also a guideline for residential. What I really wanted to know is if there is an NEC requirement for max number in commercial applications. e/mmdshunk said:Yes, there is. 180va per yoke. Window candles were just more interesting.
mdshunk said:I think he was saying that they were for the window candle circuit. I've had to do that myself many times. That's one time when you also often need to AFCI and GFCI protect that circuit, since the receptacles are often in baths, garages, and bedrooms. The window candle circuit is a more common feature in the Northeast.

PS- Don't ask what rooms may or may not have these receptacles in them. :wink:

This is only for continuous loads and receptacles are not loads.bigjohn67 said:With that said, the code also states that, in many direct and indirect ways, that you compute the circuit to 120% of the load (80% of the circuit size for the load)
bigjohn67 said:With that said, I'll leave it up to yall to figure how many 15 amp outlets you can put on a 20 amp circuit at 120 volts.
I have this argument with the guys all the time that the code does not specifically state the maximum number of outlets for a residential circuit. Once we do the math, I always win....

I agree with the others, yes.Energy-Miser said:To get back to the OP, is there a limit for number of 20a receptacles on commercial 20a branch circuits? e/m.

People that decorate in the "country style" often favor window candles. I'll put a few in the window when I notice that the British are coming.
In residences, there shall be no more than nine (9) light fixtures to a circuit.
brantmacga said:they made this ammendment w/ no regards to the wattage of each fixture? so can you only have 9 65w recessed lights on a circuit, yet have 9 600w chandeliers on a circuit (of course you wouldn't, but you know what i mean)?
jerm said:Since you asked, here's the rest:
Exception: Recessed Luminaires (Lighting Fixtures). A circuit supplying recessed
luminaire(s) shall be computed based on the maximum volt-ampere rating of the
equipment and lamps for which the luminaire(s) is rated.
I have never heard of this, could you point me in a direction where I could learn of this tradition?stickboy1375 said:For alot of different reasons, but for the most part Christian religion...
