How many outlets can be wired to the load side of a GFCI?

bake_betty

I have read a few places that the longer the wire is and the more numerous the outlets hooked up to the load side of a GFCI, the lower the threshold for tripping becomes as a result of leakage current, which may become a problem from frequent tripping. However, I cannot find any hard numbers on the limitations.

Great question — answering as the UphillTech team:

Check the specs with the GFCI manufacturer. Square D for example has a few requirements for GFCI breakers. Must be located no more than 250 ft. (76 m) from the load being served. UL requires that GFCIs must be operational at 85% of the rated voltage Other than that, there is no restriction per se for how many outlets can be on one branch circuit, residential speaking that is.
