Do You Need A Ground Rod For A Sub Panel . Since you ran a grounding conductor with the feed to the subpanel, you do not need to install a ground rod at that location. I am installing a sub panel in a shed, do i have to install a ground rod or can i just ground the sub panel to the main panel?
My House Was Built In The 1960s In Houston There Is No Ground Rod At The Service Entrance And An Inspection Of The from www.justanswer.com My question is can i add a $10 grounding rod at the sub panel, and leave the neutrals and grounds tied together instead of burying 600 ft of new wire? This panel is a candidate for further review and correction by 1) the primary purpose of a grounding rod is to provide lightning protection. If this is a sub pannel that is fed from a main pannel then you don't need a ground rod for it, but you do need to run a ground wire in the cable that feeds it.
Why do you separate the ground and neutral in a sub panel?
Exposed romex nm cable is permitted to be run exposed on the surface of the building finish. A grounded terminal bar is needed in this panel, with one or two wires to each terminal slot. Often, no more than 2 or 3 rods may be driven, due to circuit configurations and limitations to the type and number of sub panels. Grounds and neutrals were isolated to provide separate paths back to the panel.
