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.

ProfessorAs many as you like, provided there is never more than 1,920 watts being used full-time in the whole branch or more than 80 percent used by any one attached appliance.
According to the National Electrical Code, in force in many countries, you cannot have more than 10 outlets on a 15-A branch and not more than 13 on a 20-A branch circuit, based upon a budget presumption of 180 VA per outlet strap (i.e., single, duplex or triplex outlet receptacle). NFPA 70:220.3(9), 2011.
The electrical code does not have a requirement for the total number of outlets that can be installed on a GFCI circuit. It is the total wattage that will be used on that circuit that determines the number of outlets you can install. A 20 amp circuit at 120 volts equals 2,400 watts. The total safe load is 60% of that 2,400 watts or 1,440 watts. As long as you do not exceed that limit you can install pretty much as many as you want. I personally try to never exceed 15 maximum on a circuit if I know for sure they will never be overloaded.

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
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.
Can you back wire an outlet on a gfi circuit?
Don't know what you mean by back wire, but most GFCI outlets have a circuit to attach additional outlets that will be protected by the GFCI. Keep total load in minds.
Is a ground fault indicator outlet installed at the breaker box?
There are tow places to put a Ground Fault Circuit Interrupter. There is a GFCI breaker which would be installed in a breaker box and a GFCI outlet that can be installed anywhere. Most GFCI outlets allow you to connect regular outlets to the GFCI and those outlets will also be protected.
How many electrical outlet can be install to a 30amps breaker?
A 30 amp breaker is usually used for a dedicated 30 amp device. Ordinary 15 amp receptacles can not be connected to a breaker of higher trip capacity than the rating of the receptacle. The wire size for a 30 amp breaker is #10 AWG.
