What is MC feeder cable?

Aluminum MC Feeder Cable For use in power, lighting, control and signal circuits and as branch circuits and power feeders in industrial, commercial, institutional and residential installations up to 600 volts.

What does MC mean in electrical terms?

Electrical Abbreviations

What type of wire is in MC?

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.

What is 3C wire?

3C means it has three insulated conductors (as shown in the photo above) With ground means it has a ground wire. The ground wire on this cable is generally bare (not insulated) – also as shown in the photo above. 3/0 is the physical size of each of the three conductors.

Does MC cable need conduit?

Romex can be installed indoors with no conduit in certain applications. However, it is often easier and more cost-effective to use MC cable in most situations where a conduit would be required. MC cable comes with built-in protection, so it can be run indoors without a conduit.

Where is MC cable required?

Type MC cable installed on the bottom of floor or ceiling joists must be secured at every joist and not be subject to physical damage [Sec. 330.15].

Is MC cable a conduit?

Type MC armored cable can be installed in cable tray, racks, hangers, or as a cost-effective replacement for conduit and wire where specified per the National Electrical Code (NEC).

Can MC cable be exposed?

These cables can be installed either indoors or outdoors and in exposed and concealed locations. They can be direct buried, where identified for such use. Type MC cable with a nonmetallic jacket can also be used in a wet location.

What is MC metal?

MC cable (metal clad cable) is a type of cable that typically contains three insulated conductors (wires) encased in a smooth tube, ridged tube, or interlocking metal. The protective outer interlocking metal is flexible, allowing for easy bending.

How many MC wires can be bundled together?

(c) Not more than 20 current-carrying conductors are bundled, stacked, or supported in bridle rings.

What is 3 1c cable?

3/C is a single 3 conductor cable. 3-1/C is three single conductor cables.

When Should MC cable be used?

Type MC cables are widely used in 600 volt and MV power, lighting and fixture whip control applications. They are permitted for use on services, feeders and branch circuits for power, lighting, control and signaling circuits in accordance with Article 330 and 725 of the NEC.
