Question: Is a seperate grounding conductor needed on both of these or is the outside metal sheathing considered the grounding conductor? Does the mfg have to state somewhere on the package that the outside sheathing is an acceptable grounding conductor?
BX Cable (Type AC) Grounding Conductor
No separate grounding conductor is required.
Outside Metal Sheathing as Grounding Conductor
Yes, the metal sheathing of BX cable is considered the grounding conductor.
MC Cable (Type MC) Grounding Conductor
A separate grounding conductor is required for MC cable.
Outside Metal Sheathing as Grounding Conductor
No, the outside metal sheathing of MC cable is not considered the grounding conductor.
Manufacturers' Statement:
The manufacturer of the cable must clearly state on the packaging that the outside metal sheathing is an acceptable grounding conductor for BX cable. This statement is typically found on the product label or packaging.For example, the label for BX cable may state:> "BX cable with integral grounding path (metal sheathing)." Flag for review
