First, we must make some assumptions. Assume your mains
wiring is done by the "code." If your Henry is being wired to
the main service entrance panel, the neutral and safety ground
busses in the breaker panel are strapped together. If you don't
have 4 wires running all the way to the panel, just pair up the
neutral and safety ground wires on the Henry and run them to
the neutral/safety busses in the panel. Run a ground strap from
the Henry chassis to the ground rod under the service entrance panel.
If your Henry is being wired to a sub-panel, the neutral and safety
ground are not strapped together in a sub-panel box. The 4 wires
from the Henry should go to the 2 breakers, the neutral, and the
safety ground busses. The Henry chassis again being strapped
to the common-station ground rod where the mains, telephone,
antennas, etc are all bussed together.
At least that is the way I have always understood it, and done
it.
