I mistakenly ran 18ga twin lead through plastic conduit out to power 12 volt lights. Never hooked up. Now I want to power a .68 amp 120V pump on a water feature. Too many 90 degree elbows to be able to pull and replace the wire, I believe.
I read in my 1999 electical manual that I can safely use a GFCI on this ungrounded circuit at the terminus.
I want to make sure this is OK.
What about making a separate ground via a earth rod at the terminus?
Don't want to create a hazard for anyone of course, but I am trying to avoid having to but a new 12V pump and transformer or running all new service to the location.
