Intersystem Bonding Terminal Question
I am located in MI and on the 2008 NEC.
Is it permissible to connect an intersystem bonding terminal to the neutral bar of the service panel using a separate conductor instead of the GEC?

The way the requirement is written I don't think so, but would need to read the exact words. Why would you consider this?

The wall the Meter base and panel are located on has a stepped out foundation. For neatness I ran the GEC in PVC with an offset. There is not enough room to add the IBT into the run before the offset.
I don't have a copy of the 2008 NEC on hand but I believe 250.94 applies. I want to say it allows me to.

I'm thinking you probably could as long as you use the same size conductor as the GEC. I don't think I've ever done that though, so YMMV.

I generally put them around 1 - 2 feet above grade, depending on what seems to make sense with that particular house. I'd say anywhere above grade should be OK, just needs to be accessible.
