I just installed a temp power pole with a temp power box (combination
box with meter, circuit breakers, and 120/240 V receptacles for
providing temporary power to construction site) . I noticed as I was
connecting it, that there was one "bus" bar for the ground wire from
the power company and that there was a separate ground bus bar for the
"true" ground from the ground rod (and the green ground wires from the
receptacles). I also noticed that these two bus bars were not
electrically connected. The ground line (or return line) from the
power company was never really grounded to the box. Is this normal?
I'm tempted to run a bare copper wire between the two "ground" bus
bars, but would like some comments from you electricians out there.
Thanks

They need to be bonded together.

They are sold unbonded so they you can use it as a main panel or as a
subpanel (in which ground would run back to the main panel before bonding to
neutral)
