heyjaymurphy Posted December 3, 2009 Report Posted December 3, 2009 BX AC and MC cables are acceptable as grounds as long as they are installed per manufacturer's instructions and with the correct connectors. Clearly the cables that are disconnected do not meet this description, but that is a problem with the installation, not the use of the cable as a ground.

Well, AC/BX cable jackets without bonding wires were once acceptable for grounding. Those that were originally wired that way can continue being used that way. However, if you change the circuit, you can *not* use and old, unbonded AC/BX jacket for grounding today. - Jim Katen, Oregon
