How many outlets can you run on a single 20 amp breaker

brett1trout- you need to check with your elect co. to make sure. Every local has its own codes; but where I am its eight to tengood luck and GOD BLESS F.B.E,

I don't recall any code limitations on the number of receptacles on a single breaker. Your electric company will not be of much help but your local building inspector will help. Some cities have picky codes but I think the international code is mute on this point. Maybe Tk can stop by and help confirm of deny this.

For a residential setting, which I assume this is, there is NO limit to number of receptacle on a circuit. This is of course unless there is a local amendment, which some places do have.

I agree, your power company has nothing to do with this. Your local building dept will direct you to the proper place to get the correct information. Most times it is the NEC or state code.

The scientific answer is an infinite # of breakers (ignoring line losses). The more appropriate question is how much load will be attached to these receptacles.

Exactly!



To add: A 20Amp circuit will provide up to 2.4kva [or 2400 watts].

Formula: P=I(E)

The NEC does not specify a maximum number of receptacles on a residential branch circuit.


Article 210 specifies how many circuits are required,(kitchen, laundry, special appliance, general purpose, etc.) and the minimum number of receptacles that must be installed, and their placement. (usually every 12 feet along the wall, at least one on every wall, countertop spacing, etc.

If you follow the instructions, it usually all comes out in the wash.

While this is true, the NEC minimum for circuits is kind of a joke.
I don't think I could ever wire a house to absolute bare code minimum. I would feel right about it.
