I have an outside electrical outdoor receptacle question?
I have two wires from an indoor switch running to.an outdoor receptacle that is not a GFI. Off the receptacle, is a four wire (red, black, white, and green) bundle that is pulled though a conduit to another outdoor receptacle box (that IS a GFI). This receptacle is in a small compartment under a water fountain. Right now, the fountain pump is plugged into one side of the receptacle, and a set of fountain lights is plugged into the other side..
I want to continue to have the indoor switch control both the lights and the fountain at the same time, but I want to install a photo cell at the non GFI receptacle that will keep the lights from coming on until dark. Can I do it with the 4 wires in the conduit or do I have to pull an additional wire? Also, can I do it with the single GFI receptacle under the fountain or do I have to install another? Could I just put the GFI back at the original switched outlet?
