ECN Forum Forums Code Related Discussion NEC & other Code issues MC Cable used for BONDING

Hi,
Thanks for the helpful responses. I am talking about the corrugated metal under the sheath of MC cable not AC or BX type. This is used in an industrial facility. I have not seen this type of MC cable with separate bonding conductor.I am not sure if it is interlocked (probably is)but we strip it back and terminate with an MC connector, all conductors pass through the connector...insulated and bare grounding wires. I was under the impression you could not use the metal clad armor of this cable for bonding. I have seen cases where they would strip away the outer sheath and attach a clamp to the metal clad armor and connect it to building steel. Sounds like a violation to me.

Thanks
