I have a friend who has a small pond with a very old outlet for a small pump for the pond. The receptacle, which is above ground on a short post, has three prongs in a circle. He got a new pump which just has the regular three prong plug on it. Can we replace the current circular receptacle with a standard GFI? The old plug says 20 amp, 125 volt on it.
Yes you can put in a standard receptacal there. First turn off power to that circut. Then take out old recep. Put black on gold colored screw. White on silver screw and green or bare on green hexagon screw.
