Meter Box Attached To Metal Pole Barn Siding

[ricpad]

Just wondering how grounding, bonding and separation of ground and neutral apply to a situation like this: A 200 AMP service meter box is attached to the metal siding of a pole barn using unistrut channels and the neutral in the meter box is bonded to the meter box which in turn bonds it to the metal siding via the unistrut channel. The main 200 amp panel has the Ground and Neutral buses bonded and the grounding electrode conductor originates here and terminates in two grounding electrodes. Does the neutral from the service being bonded to the metal pole barn siding pose a potential problem?

That is percectly fine.

U most definitely want the metal siding and any other metal(conduit, etc) bonded to the panel.

This is to prevent metal, that shouldnt be energized, from becoming energized...

I am planning to attach my panel to a sheet of plywood inside, should I bond the outside of the building to the panel just in case?
