Grounding requirements for main panel and subpanel
You do not need a separate ground rod for this subpanel since it''s in the same building. The fact that the route is outside is irrelevant. You only need 1 ground rod if it passes the magic 25
1910.305
Unless installed in a continuous grounded metallic raceway or metallic covered cable, each branch circuit shall contain a separate equipment grounding conductor and all receptacles shall be
NEC Requirements for Panelboards and Load Centers
Electrical panels must be properly grounded and bonded to ensure safety and prevent electrical shocks. The neutral and ground must be separated at sub-panels but bonded using jumper wire at the main
Electrical grounding and bonding per NEC
The NEC requires the grounded conductor (s) to be routed with the ungrounded conductors to the service entrance equipment and it shall connect to the grounded conductor (s)
NEC Requirements for Grounding of Services | EC&M
Correct grounding of services depends upon understanding the definition and role of the grounded conductor. The neutral conductor is typically the grounded conductor connected to the system''s
