Installing a temp pole.
Power is supplied from the utility ground transformer to the utility meter. The meter is grounded with it's own ground rod. This is the only ground rod.
Typical 120/240 3 wire split phase coming into a small temporary service panel through a metal conduit.
Panel only has one bus bar where both grounds and neutrals are landed as well as the service neutral.
The single bus bar is for some reason not bonded to the panel enclosure. It is "floating" on a plastic spacer.
There is no main bonding jumper or bonding screw. I'm not that familiar with temp poles but shouldn't the panel enclosure be bonded to the single neutral/ground bus bar with a main bonding jumper?
Or would this cause neutral current to flow from the bus through the MBJ through the metal conduit to the meter?
Also why does this panel have the only bus bar floating and on a plastic fitting?
