Thanks for the responses. Found the "bonding bar" that is supposed to
be installed to ground the neutral from the power company to the box
case. The case is already grounded by the copper wire going to the
ground stake. Thanks again

One thing you need to understand. The "ground" has nothing to do with
clearing a fault (tripping the breaker on a short). All of that
current must go through the bonding jumper and back to the X0
centertap of the transformer. The ground rod is only there to
establish a local reference for the supply, so your tools and the dirt
are at the same potential. Without the bonding jumper your ground rod
is nothing but a worm chaser in a fault.

The "Ground" that comes in from the service and that is also tied to the
water pipes and gas pipes, and the pole in the dirt is a safety
precaution and has to do with lightning protection. It is not normally
part of the circuit as no current flows into the earth, basically unless
its from the sky.

The "ground" you see inside the house which is the 3rd prong is
different. Its actually just a "better" return which is used under
failure conditions. It is also not normally part of the circuit and it
too eventually ties into the earth ground. But its purpose is not
lightning protection.
