What Is Armored Electrical Cable?
Steel wire armoured cable, commonly abbreviated as SWA, is a hard-wearing power cable designed for the supply of mains electricity. It is one of a number of armoured electrical cables – which include 11 kV Cable and 33 kV Cable – and is found in underground systems, power networks and cable ducting.

Accordingly, what is armored wire used for?

Metal-clad armored cables, like those used in industrial settings, feature a grounding wire—usually an annealed bare copper wire—inside the wire bundle. This allows them to be used in open areas, such as in running through factories and plants throughout raceways and cable trays and carriers.

Secondly, what is the difference between MC and BX cable? For those who are not familiar with the difference between the two, BX has a mechanical ground as part of the armored cable wall or jacket, where MC has an "extra" green wire that is used for grounding purposes.

Beside this, where can armored cable be used?

While NM cable can be used in some residential remodeling projects, armored cable is now accepted in almost all types of construction by city planning offices and local building inspectors.

Is BX cable legal?

BX is accepted by the National Electrical Code (NEC). Older BX cables without an internal bonding strip are not accepted by NEC. NM cable is also accepted by the NEC.

Does armored cable need to be grounded?

If the fiber-optic cable in a system needs extra protection, there is an alternative to using conduit or a bonded and grounded conductive cable, such as an all-dielectric armored cable. Because all-dielectric armored cable has no metallic components, there is no need to ground or bond the cable.

How do you cut armored electrical cable?

Method 2 Cutting Armored Cable with Side Cutters
  1. Measure your cable and mark it for cutting.
  2. Bend the cable where you want to make the cut.
  3. Insert a diagonal cutter into the opening of the armor.
  4. Cut off the excess armor.
