What is Type MC cable?

What is Type MC cable?

(NEC Article 330) – Metal Clad cables are assemblies of one or more insulated circuit conductors with or without optical fiber members enclosed in an armor of interlocking metal tape, or a smooth corrugated sheath. A plastic overall jacket can also be provided.

What does type Mc mean?

Armored cable (Type AC) and metal clad cable (Type MC) provide a fast and efficient way of wiring both new construction and remodeling work. Their flexible metal armor provides mechanical protection of the electrical conductors while enabling them to bend around corners.

Why is it called MC cable?

MC cable is easier to remember because it’s an abbreviation for “metal clad” or “metallic-sheathed cable.”

What are the three broad types of Type MC cable?

Section 330.116 requires the metallic covering of the Type MC Cable to be one of three types: smooth (tube) metallic sheath, corrugated metallic sheath, and interlocking metal tape armor.

What is MC Cable vs conduit?

Metal-clad armor resists corrosion, making it suitable for areas exposed to moisture. Interlocked armor is flexible, unlike conduit or even continuously welded armor, ensuring damage will not affect inner conductors. It is also more easily installed where complex, close-spaced bends would be difficult for conduit.

What is MC in electrical circuit?

MC connectors are specially designed for low contact resistance and good stable connections under a wide range of conditions. MC means “multi-contact.” The term “multi-contact” comes from the fact that the connectors have a bunch of little spring loaded gold plated fingers that ensure good contact.

What metal is MC cable?

aluminum
A Metal Clad Cable, also referred to as MC Cable, is a corrosion-resistant metal cable containing insulated copper or aluminum connectors.

What is MC cable vs conduit?

What is a MC Cable used for?

MC Luminary Cable™ is a UL® Listed Type MC-PCS cable which combines both power and control circuits under one armor. These cables are primarily used in commercial construction projects such as casinos, condos, hotels, shopping centers and retail centers – although its usage can be quite versatile.

Is MC Cable suitable for outdoor use?

MC cable can be used indoors and outdoors because the ground wire is an insulated THHN THWN wire as well. The common use for MC cable is indoors because it can be used without conduit for a much easier installation.

What is MC electrical cable?

MC electrical cable is a very popular type of electrical cable which has many different advantages. The wire is very strong and uses unique armoring technology to ensure that your cables never get crushed or damaged.

When is MC Cable required?

Metal clad cable can be installed for service, feeder, and branch circuitry. In other words, MC is useful for wiring your main electrical panel from your service head, your sub panel (if applicable) to your main electrical panel, and your individual outlets and lighting circuits from your main electrical panel.
