Thanks for the helpful replies, folks.
The unanimous verdict is that the ground and neutral must *not* be connected
at the subpanel. The way I see it, after I disconnect them I have three
choices:
1.) Do nothing and allow surges to be shunted by the arrester breakers to
the subpanel neutral bar, where they will travel up to the house via the #8
neutral wire to the main panel and house ground.
2.) Ignore the manufacturer's instructions and connect the white wire on the
surge arrester breakers to the ground bar in the subpanel so that surges
will be shunted to the local tower ground.
3.) Move the surge arrester breakers to the main panel, where they will
supposedly provide protection for all circuits, and install MOVs between the
three service wires in the subpanel and the tower ground.
Opinions?
