I've started with a new company and they like to use the least amount of GFI's as they can. I've mostly worked commercial but now am faced with a lot of residential jobs.

How many receptacles can safely be added to the load side of a GFI ?

Thanks

There is no limit as far as the NEC (with the exception of 110.3(B)) is concerened, it would be mandated by any instructions from manufacturer, which is where 110.3(B) comes in.

Thanks.
Most of the jobs in the past have been commercial and we put a GFI at each location that it was required.

One of the other electricians that I work with, that has done a lot of residential work told me that as a rule of thumb, no more than 4 receptacles on the load side of the GFI.
This sounds about right to me.

There is no such rule. Every GFCI receptacle I've seen has been feed-through rated for 20 amps, and is considered protected by the circuit over-current device.

There is no need to cascade GFCI's. One GFCI will provide protection for down-stream receptacles (all of them) as long as it is properly connected.
