No limit in a residential setting.
Electricity in wires travels at (almost) the speed of light (i.e. 300,000 km/s)What is the recommended max distance?
Using a single GFCI receptacle and connecting to it 4 regular receptacles downstream where the last one will be about 100' away, seems too good to be true. I thought the greater the distance from the GFCI receptacle, the longer the shock will be before GFCI cuts the current.
If YOU trip one you really should worry more about that than a 200 feet round trip.If you are really worried about it, put a gfci at every location.
That way, if you trip one for whatever reason, you don't have to make a 200' round trip!
