    Is the panelboard in a remote structure? How far apart are the two panelboard's?

    To drive 100 amp 200 feet underground, will take a four wire aluminum 2/0 AWG. Also, neutral and ground have to be isolated at the remote panelboard and the remote building must have its own grounding system.

    Actually, it 2/0, not 2. At that distance 2 AWG just won't cut it.
    If it was a service panel, 2 would be adequate sine you can de-rate a service... but not for a sub-panel.

    No problem... I'm sure you have caught many of mine... not to mention errors.
