I have a question? I am installing a new 100 amp service for a detached garage. I am required to ground the panel the same as I do the meter base with a grounding rod? confused on the code thanks for the help
He would still have to drive a ground rod and have a main disco.iwirehouses said:Are you running a subpanel from the house? Bury #2 SER and bring the houses ground over on the forth conductor.
I do not think that burying SER cable is allowed.iwirehouses said:Are you running a subpanel from the house? Bury #2 SER and bring the houses ground over on the forth conductor.
I am rereading your post and I am not sure what you really have nor what you are asking. Do you have a service on this detached garage, ie meter and panel or are you feeding the garage from the house panel?cbrentfly2002 said:I have a question?

You are correct SER cannot be put underground. You could use USE instead of conduit. I also like to use conduit underground whenever possible.kbsparky said:I do not think that burying SER cable is allowed.
We install #3 THHN/THWN in PVC conduit for such a project.

Are you saying you can't sleeve SER in conduit if it is underground? I believe you can.iwirehouses said:You can't run SER underground in PVC? Buy "bury", I mean bury conduit, as opposed to running lines through the air. I would never run anything underground without conduit.
russ said:With no water service in the building, the use of a ground rod(s) is standard procedure. You may have to install two at least six foot apart, (250.56) unless you can convince the inspector that one has less resistance to ground than 25 ohms.
Article 250.56 talks about 250.52(A)(2) thru (A)(7). My understanding is that if a ground rod is driven you need 25 ohms or less.jwelectric said:Why?
There is no requirement found in 250.32 to install two rods it only referrs to 250.50
