If installing a sub panel outside for an inground pool, does the feeder grounding conductor need to be insulated?
Also, there will be 2 pumps @ 240v, a convenience receptacle, and a light. Would you just install a gfci breaker in the main panel or on the the necessary circuits outside? Just seeking input and preferences. Thanks

Thanks, up to speed on it now.
What do you think about the gfi's. Any reason not to just feed the whole panel from the main? Matter of preference?

You need to remember if you use a GFCI main on the feeder it is measuring leakage on ALL the branches. A slight leakage on one or two separate circuits might not trip the individual branch circuit GFCI but the cumulative amount would trip the main not to mention increase trouble shooting woes.

Good point Gus, as always!:slaphead:

I would never install a gfci for the panel. As Gus pointed out-- could be trouble and I am not sure it meets code as 680.23(A)(3) calls for a GFCI in the branch circuit.

Also if the panel is not on the building it is fed from then the sub panel must have either a main or use the 6 disconnect rule and also must have ground rods.
