Kelly:
Just as I suspected. I wish you could be here to share the lunch I have earned on my bet.

For EGC, just one end of the conduit is sufficient.

Or, if there is bonded cabinet with a concentric on one end and a solid, bonded metal cabinet on the other, do we need a bonding bushing on the concentric end? I say a conduit needs to be bonded only on one end. My misguided employee says both ends. Both cabinets are independently bonded. Thanks in advance.
