What code section validates "as many as you want" 220.14 j?
A 20a breaker can actually hold more than 20 amps. It will not magically trip at 20.0000001 amps, but the higher the amperage goes, the quicker it trips. 21 amps may never trip it, 22 amps may take 4 hours, 23 amps may take an hour, 24 amps may take 10 minutes.... It's called a trip rating curve or something like that.
I'll be there! Where is it?
the most by 220.14 20 ampsx120volts=2400va/180va=round down =13
rule of thumb=10 receps/circuit
Still why are you paying for the slot. What is going to plug in there a commercial copy machine that should be on a dedicated circuit!I only use Industrial grade receptacles
What I actually do is to assign (i.e., on the Panel Schedule) a value of 180 VA to each duplex receptacle. Then I make sure that the total “assigned” load on any 20 amp receptacle circuit does not exceed 1920 VA. Thus, I never put more than 10 duplex receptacles on a 20 amp circuit. Most of the time, the number is smaller than that.
Please note, however, that we are now discussing design considerations. Nothing in the NEC would prevent me from designing a 20 amp branch circuit (residential or otherwise) that had 50 duplex receptacles.
You know us. Tell us where it's prohibited.I beg to differ 220.14 all occupancies, 220.16 additions to dwellings. I ask, can you tell me where in the code you can place as many as you want?
Code section?My interpetation of the code tells me that there is a limit based on the va.
On that, absolutely. Plus, I'm one of the guys here who prefer keeping lighting and receptacles separate in other than kitchens, too.I would add that a workman like manner would not install an endless number on a circuit, I hope you would agree.
I don't do resd. 2 questions how many recp. can you put on 15 amp circuit i say doesn't matter. the guys say you can only go 80% of the breaker ampacity i laught at them hope i am wright
Please read all of the words in 220.14(I).why would 220.14 and those following, not limit the number of receps and that is for dwelling and all occup. that is where i feel it is prohibited, the nec is not designed to be for untrained persons
I beg to differ 220.14 all occupancies, 220.16 additions to dwellings. I ask, can you tell me where in the code you can place as many as you want?

the 3va/sqft is for calculating the load for your service. 220.14 determines the load in dwellings as well, i differ with you on the fact that you can have as many as you can.
Lefty, lets think on this.
Lets say you decide to put a bedroom on it's own circuit and install the code minimum receptacles, lets say that is one on each of the walls for a total of four duplexs on the circuit.
I think can we both agree that circuit is not likely to be overloaded.
Now lets take the exact same bedroom and place 3 additional duplex receptacles per wall just because the customer wants that for convenience.
Now we have a total of 16 duplexs on that circuit.
Is it now overloaded?
Will the homeowners buy more electrical stuff to plug in just because there are more receptacles in the room?
I hope we are all using a workman like manner in placing the quantity of receps.
