Conduit bonding at Penetrations in Steel Sided Buildings

[natfuelbill]

I have a steel framed and steel sided C1D2GD building. Would a conduit running into the building be required (or would you recommend) to have bonding from the conduit to the steel siding at the drilled penetration?

Normally one would expect a steel framed and sided building to have a pretty effective bond between the frame and the siding, seeing as there are many screws securing the siding to the framing.

The conduit is typically tied to the building frame in many places (think conduit clips). I don't see how one could get a much more effective bonding.

Where is this conduit comming from? Is this the feeder to the building?

Would it matter?

The conduits are AC, signal, branches kind a mix....
