Number Of Receptacles In Reference To Hallisseydesign


This is my first post I am a Electrical Contractor out of New Orleans I have been reading some of the posts and I felt compelled to comment on a paticular post that Hallisseydesign posted. I belive Hallisseydesign may be somewhat correct with his statement about the number of Receptacles on a circuit. Receptacles are calculated at 180 volt-amperes per strap. Therefore, when the source is 120 volts, the rating of each receptacle is 1.5 amperes(180/120= 1.5). Now knowing this we can say that ten receptacles are permitted on a 15-ampere overcurrent protective device (15/1.5= 10). Thirteen receptacles are permitted on a 20-ampere overcurrent protective device (20/1.5=13.3). Of course this is used with commercial and not residential. If I am incorrect please let me know.

Welcome to the forum!!

Some jurisdictions DO have amendments to the NEC that limit the number of receptacles on a circuit.

Not that I disagree with you, but no way am I putting 13 receptacles on one 20 amp circuit, unless the (stamped) prints say to.

Can you imagine 13 secretaries with 13 space heaters....

Right... in commercial work. Dwelling units have no such limitations.

The statement I made is just fact in the NEC code but by no means would I ever put that many receptacles on a circuit. But I do thank everybody for their replys.

Of course this is used with commercial and not residential. If I am incorrect please let me know.
...and therein lies ONE of the many faults with Hallisseydesign's logic.

Commercial is rated at 180VA, but not resi. To even attempt to equate the two types of buildings is completely erroneous. Hallisseydesign was incorrect with his statements ~ based on NEC code. Hallisseydesign had mentioned some "other" code, when asked to provide documentation of this phantom code, he promptly disappeared.
Had he simply provided an amended version of the NEC that was adapted in that region, he might not have been brutalized so unmercifully.

But that's not your problem

I'd do it in a heartbeat ~ provided print did not show otherwise.

Let's even reduce your 13 example to 4 ....4 space heaters @1500W = 6000W ; 6000w/120v = 50A

Even a circuit that is well below the minimum NEC standard is in jeopardy from the unknown variable of a person.

Space heaters and secretaries are a great money making combination!

That is, if they didn't find a receptacle 10 feet away on another circuit that they can chain together 3 or 4 plug strips to get their space heater up and running.

Sounds like a game show.

Instead of "I can name that tune in two notes". "I can trip that breaker with a space heater and a worm drive saw".
