I put an automatic gate in but I did not know that I was going to when I built the house. I have a GFI outlet on the back of my house about 200 feet from where I need power. What size wire should I use. Its 110v

Others mentioned you need to list the current of the load.

One other thing is that 200 feet may be too long.

Numbers vary from 150 to 250 feet is the maximum length of wire from the
outlet to the load of a ground fault outlet. They may trip from the
internal leakage of the wires if long enough.

I use the term internal leakage very loosley as there can be several
factors determining the tripping due to wire length.


Good point. IDK what the code says regarding electric gates and GFCI. But he
may be better off running it non-GFCI to the gate and then installing a GFCI there,
just before the gate. Having a GFCI receptacle at the gate might be a good idea
too, handy for future repairs, plugging in a chain saw, Xmas lights, etc.


That's pretty much what I ended up doing here, on my project to run power
to a storage shed in the back yard. The run was 120 feet so the electrician
put in a standard breaker at the service panel at the house, then a pair of
GFCI breakers inside the shed, one for lighting and one for receptacles.
His reasoning was that I won't lose the lights if I trip the receptacle
breaker. Handy for working after sunset.
