How countless receptacles can I location on a 20 amp breaker if it"s a 120 volt circuit? How numerous on a 15 amp circuit? I"m trying part on mine bathroom and also bedroom. Help would be appreciated.



There"s no limit to the variety of receptacles that can be top top a circuit in a residential dwelling. Code does point out a minimum variety of receptacles required in a room (NEC 210.52(A)), based on the length of the walls. The password does not, however, limit the number of receptacles every circuit.

In industrial/commercial spaces, 180 Volt-Amperes (VA) is used when calculating receptacle loads. This worth is regularly used together a tip in residential applications as well. Because that example, offered a 15 ampere 120 volt circuit, you might have 10 receptacles
180 VA.

15 A * 120 V = 1800 VA1800 VA / 180 VA = 10

So a 20 ampere 120 volt circuit, could have 13 receptacles
180 VA.

20 A * 120 V = 2400 VA2400 VA / 180 VA = 13.333

These number are just a guideline, and also have no real meaning in residential populated units.

You will have to keep the bathroom and bedroom circuits separate, and also the toilet receptacles will have to be gave by at the very least one 20 ampere branch circuit (NEC 210.11(C)(3)). For this reason you"ll need at least two, 20 ampere branch circuits. One because that the toilet receptacles, and also one for the bedroom receptacles.


I do see just how the an outcome of how numerous receptacles there have the right to be for sure on a 20 Amp at any given time... I also figured out A*V=W. Then, to figure out how many receptacles, divide your complete watts through the number of amps * receptacles... Due to the fact that 120 V = 180 VA *10 = 1800VA. 20A * 120 = 2400VA ÷ 180VA =13 recepts. Alright. Got it. I have actually a far better understanding just how to wire a 20 Amp circuit.but to it is in safe and also you shouldn"t want an ext than 8 receipts. Top top a 20 Amp circuit: 3 desk lamp boxes, 3 move boxes, and 2 wall surface socket boxes.
