Quote from: mjp24coho on January 04, 2014, 12:51:55 PMThere's a separate ground rod for the cabin and one for the detached garage. If there is no ground wire running between the cabin and the detached garage (I'll need to check if there is), would I need to do a separate nuetral-to-ground bond in the cabin also?
Quote from: tecnodave on January 04, 2014, 09:45:01 PMAs I read the NEC 2008 there is no instance that you would be permitted to run L1 , L2 , and Neutral with no ground wire to the separate building.
Quote from: Halfcrazy on January 03, 2014, 01:55:31 PMHere is how I would do it. Presumably one of these panels has the AC neutral and ground bonded. In that panel I would put the red and black on the AC hot lead and the green to ground. In the panel without the bond as the neutral floats sort of I would wire it Red to AC hot, Black (with included white heat shrink) on the AC Neutral and green to groundWe tend to over look Neutrals and in cases where the bond is a ways away this can be problematic. Electrically it is at ground potential but during a strike or very strong surge the resistance in the wire can make it look isolated from ground.Ryan
