How many outlets are there?

Up to 12 on a 20 amp circuit. Up to 9 on a 15 amp circuit. But use common sense. If the circuit will be heavily loaded, as in a home office, then do not install that many.


How many outlets can you have on a gfi breaker?

Depends on the breaker. If the load at the outlets is unknown then the standard rules of 80% apply. You can only load a circuit 80% of it's maximum value. For instance, if you're connecting your GFCI outlets to a 15 amp breaker you can only have a maximum of 12 outlets. If it's a 20 Amp breaker then you're allowed up to 16 outlets and so on. In the US, you are limited to 13 receptacles on a 20 amp circuit and 10 receptacles on a 15 amp circuit in commercial or industrial installations. Any or all of these can be gfci-protected. You can install one gfci, the first one from the panel, and protect any or all the others from that one.


How many wall outlets can you have in a circuit using a A breaker?

Assuming this is not an office of a place where lots of the outlets will be used to power items that draw lots of current on a 15 amp circuit wired with 14/2 wire I would limit it to no more than 10 outlets and lights combined. On a 20 amp circuit wired with 12/2 wire I would limit it to a 14 outlets and lights combined. There is no limit in the code. You just use common sense based on what is going to be used on this circuit.


How many eletrcal outlets can you have in a garage?

There is no limit as to the amount of circuits you can have in a garage. If you mean how many devices on a 15 amp single circuit breaker then the answer is 12. Be sure to total in light fixture outlets and switch boxes.


What might cause low voltage at one outlet on a multioutlet circuit?

its an overload on the circuit breaker the 3 outlets are on.. many times groups of outlets are on different circuit breakers.. even though they are in the same room... especially if some are on a gfi outlet
