I'm helping out a fellow contractor and doing some re-wiring at a high rise condo. It's a fairly new building and the original branch circuit wiring was done with 12/2 AC. We are now adding receptacles and lighting to existing circuits and are using 12/2 MC. My friend's contention is that we do not have to bond the green wires to the JB's, the spiral aluminum jacket on the MC takes care of that. My contention is that the aluminum jacket is not an effective ground path and the MC should be grounded via the green wires. There are no situations where isolated grounds are required and all receptacles are self-grounding.
We are also not using any red heads. I know we've had this discussion in the past regarding red heads and MC cable but if it were my job I would use them just as a precaution.
Any thoughts would be appreciated. Thanks.
