Considering this, 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 above, what type of wire is in MC cable? MC cable contains conductors from 18 AWG through 2000 kcmil for copper and 12 AWG through 2000 kcmil for aluminum. Typical branch circuit Type MC cables have copper conductors with THHN, THHN/THWN or XHHW insulation and are suitable for circuits up to 600 volts.
Similarly, you may ask, how do you cut armored cable with a hacksaw?
A third option to cut cables is to use a hacksaw. This method is similar to using side cutters. First bend the cable until the armor begins to pop open. Next take the saw blade and cutting at a 45° angle, cut through the remaining armor avoiding coming into contact with the conductors.
How do you use Armoured cable?
MC cable has a green-insulated ground wire, used like the bare ground wire in NM cable.
- Step 1: Bend Cable. Bend the cable about 10 inches from its end and squeeze with your hand until the coils of the armor come apart.
- Step 2: Twist Cable.
- Step 3: Cut Exposed Coil.
- Step 4: Cut the Wires.
- Step 5: Remove Excess.
