Sub panel install to workshop. If I install a panel with the main breaker on the panel how do I wire it. Separate ground from insulated neutral, do I install ground rod. Ground wire from main to this sub that has the main breaker on it.


Thanks

You will probably need to get an add-on ground bar for the sub-panel.
DO NOT install the green screw or bond strap.

If workshop is a detached structure, then a ground rod must be installed.
