In older types of armored cable a aluminum strip was used as a bonding medium. This strip was wound back over the outside of the sheath and the connector on the end of the cable was used to secure it. Test were made to see how much short circuit current could be handled by this type of installation and it failed usually by burning open and leaving no ground at all. Now all armored cable has a separate, usually bare copper wire, embedded in with the current carrying conductors. This ground wire is now terminated onto a lug found in the junction box or on the device the cable is connected to.

Can you use armored cable to wire 277 volt lights?
Yes.
What color are the terminals of a standard grounding type receptacle?
green wire is gr gray wire is neutra
Have a black white and red wire for a dryer plug what ones the ground wire?
It would be green or bare. That's if you have a grounding wire in the cable. You may not have one.
What size ground wire is needed for 20 amp?
A #14 wire will do fine for grounding a 20 amp device. That is the size of the ground wire in a 2 conductor # 12 wire building cable.
Why is the ground wire smaller in your 8 2 with ground wire?
The grounding wire is not intended to be a load-carrying conductor in ordinary use, but rather a SAFETY conductor. Grounding wires are often "one size smaller" than the associated load conductors in the same cable.
What is single core armored cable?
Armored electrical cable contains insulated electrical service wires protected by a flexible steel covering. Unarmored electrical cable has no protective flexible steel covering, its covering is made of plastic. <><><> Armored cable (BX) is the older version of Metal Clad cable (MC). It was flexible steel covered wire that used the steel as it's Ground. BX was a poor grounding system so it was replaced with MC which looks similar but has a separate Grounding conductor. MC is most often made with aluminum as its cover. Armored cable if used today will refer to MC type wiring. <><><> Some kinds of armored cable are in fact made to a tougher standard than the ordinary soft wire strand types of shielded cable that are used for hooking-up antennas. The 'armor' is actually a thin flexible metal film that better protects the wire or wires inside from damage in high use or high traffic areas. Such kinds of armored cable are also used in radio frequency assemblies in electronic equipment.

What is SWA when used to describle an electric cable?
Steel Wire Armored.

Yes.
What is does PILSWA stand for?
paper insulation steel/wire armored cable
What color wire is grounding conductor?
The grounding conductor is green, green with a yellow tracer or bare copper.
What color are the terminals of a standard grounding type receptacle?

Is the green coated wire for equipment grounding?
Yes green wire is the earth wire (Grounding)
