Default Insulated ground armored cable

Looking for someone to share a 250 ft. coil or 1000 ft. reel of MC TUFF insulated ground cable. Lightweight steel armour for EMI. Second green/yellow striped conductor for insulated/technical ground. Preferably 10 gauge, two conductor, with 2 grounds.

Preferrably someone to share in the MD, DC, VA area, to avoid shipping cost of heavy cable, which is about 27 lbs/100'.

For info on this cable, see the link below. Look at item # 1708B42T80 or 1708B60T80.

I'm looking for 75-100 ft of the purchase.

This should be available at your local hardware store. It's also known as "Greenfield" or "BX". (Which actually refers to its ungrounded predecessor in the '30's.)

I just gotta' ask, what are you using it for? With 75-100 feet it must be residential...

I haven't found cable with TWO grounds at the local hardware store. Normal BX sheath can serve as a ground, but in some localities this might not meet code.

I'm looking to use it as a dedicated branch circuit for my entertainment system, and providing a technical ground line in addition to safety ground. It is not available at HD or Lowes. I haven't checked local electrical supply houses, yet, to see if I can get such an item in 100' coils.

Just get a 4 conductor and use 2 as ground.

Does not matter what color the jacket is, is it?

it doedsn't matter as long as you mark the ground wires with the correct colours at the terminus.


Why does one need two grounds anyways? What's the benefit? Does it meet code?
