Grounding and Bonding Issues-Steel Building

[A/A Fuel GTX]

On a side note, I brought the #6 bare GEC in the building from below grade and protected it with EMT up to the panel. I was informed that this creates a choke? He "suggested" I put it in sched 80 pvc instead. Anyone ever heard of this?

Yes, the AHJ is correct. If you use a metallic raceway for the GEC, it must be bonded to the GEC at both ends usually via a bond bushing. RNC is definately the better choice.

Thanks Tom.

Negative on the footings. There are none in this building type.

So they just pour a slab with no footings and build walls on that? I'd say the concrete slab is your foundation and would technically qualify in that case.

Kind of an odd method, though.

Hi George. The main upright poles for this building are driven 8 ft into earth. Horizontal perlins are installed and the walls are hung on that. Also the slab actually floats on certifoam so it does not contact earth. That's why I was going around and around on this.
