George you are worrying me now, are you the type of inspector that makes the rules up as you go along?
Don already went over this I will try to make it clearer.
250.104(C) Structural Steel. Exposed structural steel that is interconnected to form a steel building frame and is not intentionally grounded and may become energized shall be bonded to the service equipment enclosure, the grounded conductor at the service, the grounding electrode conductor where of sufficient size, or the one or more grounding electrodes used. The bonding jumper(s) shall be sized in accordance with Table 250.66 and installed in accordance with 250.64(A), (B), and (E). The points of attachment of the bonding jumper(s) shall be accessible.
In order for you to be able to require any electrician to bond steel it has to meet all of the following.
It must be exposed
It has to form the steel frame of the structure.
It has to be likely
to be energized.
The opening post asked this;
Does a steel I Beam supported by steel post setting on concrete need to be bonded?
If that is the extent of the steel you have no authority to ask for it to be bonded.
I do not take the term "may become energized" to be all encompassing.
In my opinion you would have to show a way or reason it may become energized.
"may become energized" is the rub. If you lay cables or conduit over or along the steel beam, I would lean toward "may".
You do require conduit to be grounded and you do require proper supports for cable systems right?
So how would this lonely piece of steel become energized?
