Receptacles On An Circuit

[mstrlucky74]

To determine how many on a circuit is the calculation = VoltsxOCPD Amps then divide that by 180va? Thanks.

That works in "general terms" if you keep in mind that calculation is for "other outlets" listed in 220.14. There are many instances where that "formula" does not apply such as specific loads, multi-out assemblies, etc. You need to review 220.14 before applying.

120V x 20A x .80 = 1920VA divide by 180

Unless specific loads are known for specific recepts

If this is a dwelling you would use the 3va/Sq ft calculation to find the minimum number of circuits. How many you put on a circuit is not limited by your calculation.

Why 80%?

this only applies to non dwellings the reasoning being that non dwelling outlets are installed where they will probably get used and not by spacing requirements as dwellings are.

Good point.

I thought that was obvious

i must also ask why the 80%? There is no need to figure general receptacle circuits for continuous loading.

Speaking of obvious, I am waiting on your reply to Post #5
