Is copper clad aluminum wire good?

Solid copper cables are the preferred cable type for transmitting data over longer distances. Weight: Copper clad, specifically aluminum, is a lightweight cable type. Durability: Steel is the more durable copper clad option, however solid copper is very durable as well. Conversely, copper clad aluminum isn’t as strong.

Is MC cable waterproof?

The metallic covering is impervious to moisture. A jacket resistant to moisture is provided under the metal covering. The insulated conductors under the metallic covering are listed for use in wet locations.

What is MC cable?

MC Cable, by most common definition, is a factory assembly of one or more insulated circuit conductors enclosed in an armor of interlocking metal tape or a smooth or corrugated metal sheath.

Where are MC cables used?

Type MC cables may be installed indoors or outdoors, in wet or dry locations, hazardous locations (Class I, Division I), in cable tray, as aerial cable on a messenger, in any approved raceway, direct burial (where identified), or encased in concrete (where identified).

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.

Can you bury MC wire?

Type MC Cable without an outside nonmetallic jacket can be installed in an “other space used for environmental air” in accordance with Section 300.22(C). 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.

Can you use MC cable outside?

330 of the NEC mentions that MC cable can be used indoor and outdoor but does not make mention of it being allowed or disallowed for use in damp environments. It does state that when used in wet locations there must be a corrosion-resistant jacket to protect the conductors.

Can you run MC in 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).

Is MC cable grounded?

AC uses a bare aluminum bond wire plus the armor as the ground path, Traditional Type MC Cables utilize a green insulated grounding conductor and the armor is not an approved grounding means. AFC offers MC-Quik® which utilizes a full size bare aluminum bond wire with the armor as an approved grounding means.

What is MC cable rated for?

MC Cable can be used in places of assembly of 100 people or more, such as studios and theaters. Voltage ratings should not exceed 600V in any application.

How many conductors are in MC cable?

MC cables have 2 or more solid or stranded conductors in sizes 18 AWG and larger.
