No. it is plastic.
Armored electrical cable contains insulated electrical service wires protected by a flexible steel covering. Metallic Conduit is a tube or pipe though which we lay electrical cable.(Most commonly lighting cables).
Cable that has no armor.
Same installation as non armored cable.
The difference between Armored cable and Metal Clad cable is that the MC cable has a EGC (Equipment Grounding Conductor). Both cables are armored, and look almost identical so watch out.
It lets you know what material the cable is made from.
Armored cable is used in environments such as a front yard where environmental conditions make an armored cable susceptible to damage. If the question is asking about Shielded/Screened cable, that has a small thin metal foil wrapping that is used to "screen out" most external signal noise from the cable.
Steel.
For protection of the wires.
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.
The diameter of a 6 core armored cable can vary based on the specific type of cable and its insulation materials. Generally, a 6 core armored cable can have an outer diameter ranging from approximately 20 mm to 40 mm. For precise measurements, it's best to refer to the manufacturer's specifications or technical datasheets for the specific cable in question.
NM (non-metallic) or armored cable should ideally be installed at least 1 1/4 inches from the front edge of the stud. This distance helps protect the cable from potential damage caused by nails or screws that may be driven into the wall. Proper placement also ensures compliance with electrical codes and enhances the safety of the installation.
Romex is the trade name for non-metallic sheathed cable manufactured by Southwire Company, LLC.
