Grounding metal conduit system

[kbsparky]

We have encountered an insteresting scenerio:

A run of 2" conduit between an outside disconnect box, and the inside load center. Ho-hum, except that part of the run is metal EMT, and then it goes outside to an LB, and from there it transitions to PVC.

I was worried about the proper grounding of said metal conduit, since there was this short section of PVC in there. Even though the EMT is grounded at the far end, I wondered should I install a grounding lug inside of the LB, and bond that end of the metal pipe run to the ground bar in the outside disconnect as well?

I say bonding at one end is ok. I assume there's an egc in the pipe.

....I assume there's an egc in the pipe.

Yes, that is correct. Sorry for leaving out that important information. :roll:

Where you are not using the raceway as the EGC you don't need to bond both ends, the fact the the raceway is grounded and bonded at one end is sufficent to meet the requirments of 250.134.
