How countless receptacles deserve to I ar on a 20 amp breaker if it"s a 120 volt circuit? How plenty of on a 15 amp circuit? I"m trying part on mine bathroom and bedroom. Assist would be appreciated.



There"s no border to the number of receptacles that deserve to be ~ above a circuit in a residential dwelling. Password does point out a minimum number of receptacles forced in a room (NEC 210.52(A)), based on the length of the walls. The code does not, however, border the variety of receptacles every circuit.

You are watching: How many outlets can you put on a 20 amp circuit

In industrial/commercial spaces, 180 Volt-Amperes (VA) is provided when calculating receptacle loads. This value is often used together a pointer in residential applications together well. Because that example, given a 15 ampere 120 volt circuit, you can have 10 receptacles
180 VA.

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

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

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

These numbers are just a guideline, and have no real definition in residential dwelling units.

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


I do see just how the result of how countless receptacles there can be safe on a 20 Amp at any kind of given time... I also figured out A*V=W. Then, to number out how plenty of receptacles, division your complete watts through the number of amps * receptacles... Because 120 V = 180 VA *10 = 1800VA. 20A * 120 = 2400VA ÷ 180VA =13 recepts. Alright. Gained it. I have a far better understanding just how to cable a 20 Amp circuit.but to be safe and also you shouldn"t want more than 8 receipts. ~ above a 20 Amp circuit: 3 desk lamp boxes, 3 switch boxes, and 2 wall surface socket boxes.
