There"s no limit to the number of receptacles that deserve to be ~ above a circuit in a residential dwelling. Code does specify a minimum variety of receptacles compelled in a room (NEC 210.52(A)), based upon the size of the walls. The password does not, however, border the variety of receptacles per circuit.

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

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

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

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

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

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

You will need 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)). Therefore you"ll need at least two, 20 ampere branch circuits. One for the toilet receptacles, and also one for the bedroom receptacles.

I carry out see exactly how the result of how plenty of receptacles there deserve to be safely on a 20 Amp at any kind of given time... I also figured the end A*V=W. Then, to figure out how many receptacles, divide your total watts through the variety of amps * receptacles... Due to the fact that 120 V = 180 VA *10 = 1800VA. 20A * 120 = 2400VA ÷ 180VA =13 recepts. Alright. Obtained it. I have a much better understanding how to cable a 20 Amp circuit.but to it is in safe and you shouldn"t want more than 8 receipts. ~ above a 20 Amp circuit: 3 desk lamp boxes, 3 switch boxes, and 2 wall socket boxes.
