New here, thanks in advance for any help! My question is-
I am building a new house/shop, my main 200 service and panel is on the pole and I will have a 200 amp sub panel in the house/shop. I know the main panel is to be bonded and the sub panel is unbonded. My question is for the sub panel what wire size do I need to run (250’ underground) and do I run a ground wire from the main panel to the sub panel or do I just drive my 2 grounding rods in for the subpanel? My thought is if the main panel is bonded and I run a ground from it and even though the sub panel is unbonded won’t there still be continuity between the ground and neutral in the sub panel since the main is bonded?
