    Yes! You also need to know the distance between the main panel, whether you will be using above ground cables, below ground cables.

    Is the sub panel going to be in the same building or a separate building? If a separate building, you will need a separate grounding rod and, Neutral must be isolated from Ground within a sub panel.

Will this work properly if when wiring a sub-panel for 240v can one of the 3 aluminum 4 gauge wires in the pvc underground pipe be used as the neutral wire if that wire is bare? I intend to attach the ground bus at the sub-panel to a ground rod using 6 gauge bare copper wire.
