armored cable


i appreciate your help. i (my youngest son just bought an older house im trying to help) have a circuit coming from the panel with metal armored cable it served a space heater which the city told us we had to remove.i did i thought i would use that circuit for some basement outlets as joe wants to finish part of the basement ..my question is can i use 3 wire romex from a junction box where the unused circiut ends and run some outlets into the family room and have them be grounded ? or do i need to get more armored cable and metal boxes to have properly ground outlets? thanks

You can easily just use bonding bushings if you felt the need to use plastic boxes.

Not really sure what your trying to say, but that internal bond wire is only for using the AC as a grounding conductor, it was never ment to be bonded to the box or the device. Just want to make that clear.

Unless the armored cable has the bond strip in it, you can't extend that circuit. You could always get some romex and take it straight to the panel and eliminate the old cable altogether.

I am under the impression that the OP is extending a circuit with no egc I thought that if you extend a circuit you have to upgrade the whole circuit. Please correct me if I am wrong but this is my understanding.

The OP is wondering if the armor of the cable can be used as an EGC. The answer is maybe. It depends on the bonding strip inside the cable, or lack thereof.

Also isn't there a max distance to it like 6' if you use that as the grounding path? I am not sure. But my question was I thought that you have to replace that ungrounded stuff with wire with ground not just use the case as the ground. I understand what you are saying I just wanted to clarify what I was trying to say.

6 feet is the limit for flexible conduit as a grounding path. Armored cable, as a factory assembly, and containing the bonding strip, has no limitation on length.

And yes, if it doesn't have a ground and cannot itself be used as a grounding path, then it must be replaced.

Ok thank you for clarifying this for me.
