I'm in the process of hooking up a new pool heat pump at the back of our home, but I need to run wire # 6 wire from main panel in garage to rear of house.
I didn't have any space left in main panel, so I'm adding a subpanel next to the main one (60 amp, #6 wire).
My question is: if I use #6-3 wire with ground from the subpanel to back of house, can I add another subpanel attached to rear of home for possible future use, or should I just use #6-2 wire with ground and use a disconnect only?
I know there's extra costs for the additional subpanel instead of just a disconnect box, but I wasn't sure if you can add another subpanel to a
(I already have the #6-3 w/grd wire, and could use this either way, right?
I assume if I use a disconnect only, only the 2 hots plus the grd. is needed from subpanel to disconnect.
Thanks for any help with this questions
