Proper configuration for hardwiring a (sub)panel to temporary electrical service pole/panel.

[conrad503]

I'm helping a friend of mine so some renovation in the basement of his home. He has a temporary service panel on a hill with two 20 amp breakers that are designed to feed the receptacles in the panel. He's hardwired a 10/3 conductor from one two pole breaker to a service panel inside the structure approximately 40 feet away. The panel has two 20 amp breakers. One feeds a single 240v receptacle and one feeds a duplex 120v receptacle attached to the panel enclosure. Currently, the panel has a single neutral/ground bus which is bonded to the chassis. This bus is ultimately connected via the 10/3 to the neutral and ground of the temp service panel on the hill, which is itself grounded to earth via an 8' rod. The grounds and neutral terminals of both the receptacles on the panel are also connect to this single bus.

I'd like run equipment from this interior panel without concerns about safety. Can someone verify that this is the proper configuration please? Or does something need to be hooked up differently. Specifically, is it proper to have a single bus for both ground and neutral, and should this bus be bonded to the panel chassis.

Yes, I am aware that there are many reasons why this could be a bad idea/in violation of the NEC/local codes, etc., but due to the very inconvenient location of the temp pole, I think it's highly likely it will remain until the weather head and permanent service panel are installed in a few months. Thanks for any input.
