You are watching: How many ground rods for 100 amp service
All other circuits space serviced native the subpanel.
My understanding of NEC is that each panel needs two grounding rods at least 6 feet apart.
My residence uses PEX yet there is a copper key coming in top top the opposite side of the crawlspace.
Do I require two full ground rods per panel? therefore four, total, rods?
Do not attach the below panel to grounding electrodes. A grounding conductor should be run earlier to the main organization panel. The main business panel is the only link to a grounding electrode system in a single building there is no a separate method such as a genset. The underground steel pipe can be supplied as an electrode, yet it sound distant. For this reason you must install 2 ground rods near the company entrance and connect those to the company panel.
