I know this has been covered before, but I need clairification.
I have an older home (built in 1940), but it has a new 200 AMP service installed and inspected 2 years ago.
I just had a new detached garage built with GES (rebar conected to rod).
I intend to install a 100AMP subpanel (fed from the main panel) to a 60 amp breaker.
I will use underground direct burial cable from the main to the subpanel, about 50ft.
The subpanel ground bus will be grounded to the GES and the neutral will not be connected to the ground bus in the subpanel. The ground bus will connect to the grounn bus at the main panel.
What is the correct wire to run from the main to the sub and what size ground is required from the sub panel to to the GES?
And, have I configured this correctly?
Thanks,
Tim
