Metal-Clad (MC) Cable is a popular wiring option in commercial settings, especially in buildings and garages. Its versatility, durability, safety, and cost-effectiveness make it a great choice for electricians. MC cable is defined as an assembly of one or more insulated circuits, often enclosed with an armour of metal tape or a metallic sheath. It can be installed both indoors and outdoors, although it is primarily rated for dry locations. For wet locations, PVC-jacketed MC products are available. MC cable is also known for its ease of installation, saving valuable labour hours by eliminating the need for conduit installation in most cases.

What You'll Learn
MC cable is primarily used in commercial settings
MC cable, or Metal Clad Cable, is a common choice for wiring in commercial buildings and garages. It is used every day in the electrical industry and has a wide variety of uses. Its versatility, durability, and reliable performance make it a popular option for commercial settings.
MC cable is primarily designed for indoor use and is well-suited for dry locations. It includes conductors encased in a protective metal jacket, providing mechanical protection. This design also allows for flexibility in installation, as it can fit into tight framing spots and has an unlimited number of bends. The cable can be used in both exposed and concealed settings, such as walls, ceilings, and other visible places.
In commercial settings, MC cable is often used for services, feeders, and branch circuits. It is particularly useful in construction projects and can save time and money compared to other wiring methods. For example, it reduces overall installed costs by approximately 30-50% when compared to conduit and wire installations.
While MC cable is predominantly used in commercial settings, it can also be applied in residential settings. When used in homes, it is typically installed behind walls or in areas out of plain view. However, it is important to note that MC cable should not be used in areas where it is likely to be damaged by external forces or heavy equipment.
Overall, MC cable is a versatile and reliable wiring option that is well-suited for commercial applications. Its ease of use, durability, and cost-effectiveness make it a popular choice for electrical wiring in commercial buildings and garages.

It is a common choice for wiring in commercial buildings
Metal-Clad (MC) Cable is a popular choice for wiring in commercial buildings and garages. It is used every day in the electrical industry and offers a wide variety of uses. It is a factory assembly of one or more insulated circuit conductors enclosed in interlocking metal tape armour or a smooth or corrugated metal sheath. It is also known as BX cable.
MC cable is primarily used in commercial settings, but it can also be used in residential settings. It is a common choice for wiring in commercial buildings due to its durability and reliable performance for electrical wiring. Its full-sized equipment grounding conductor provides enhanced safety.
MC cable is versatile and can be installed both indoors and outdoors. It is primarily rated for dry locations, but it can also be used in wet locations with proper fittings. It is important to note that the sheathing of the MC cable is not inherently moisture-proof, so using a PVC-jacketed MC with appropriate fittings is necessary for compatibility with wet locations.
MC cable provides greater protection against the elements compared to other cables, such as Romex cable. It also offers additional protection against pests due to its metallic casing, which protects against biting damage from rodents. It is grounded through its metal armour or through an internal ground wire.

It is durable and reliable for electrical wiring
Metal-Clad (MC) Cable is a common choice for electrical wiring in commercial buildings and garages. It is also used in industrial and residential/commercial buildings. MC cable is durable and reliable for electrical wiring, and its versatility makes it a popular choice for electricians.
MC cable includes conductors encased in a protective jacketing, which makes it suitable for both indoor and outdoor use. However, it is primarily rated for dry locations. When used in wet locations, it is important to use PVC-jacketed MC with appropriate fittings to ensure compatibility and provide the necessary insulation against moisture.
MC cable is available in various types, each designed for specific applications. The most common variety features three insulated wires (two circuit conductors and a green equipment grounding conductor) protected by a flexible armour usually made from aluminium. Other types include MC-HL Cable, designed for hazardous locations; Jacketed MC Cable, suitable for wet locations; Aluminum Interlocked Armor (AIA) MC Cable, which offers flexibility and mechanical protection; and Continuously Corrugated Welded (CCW) MC Cable, which provides superior protection against moisture and corrosion.
To ensure the durability and reliability of MC cable installations, it is important to adhere to guidelines such as those provided by the National Electrical Code (NEC). This includes proper support, securing, and maintaining appropriate bending radii. Following these guidelines helps to maintain the integrity and performance of MC cable installations, making it a safe and reliable choice for electrical wiring.

It is versatile for both indoor and outdoor use
MC cable, or Metal Clad Cable, is a popular wiring option in commercial buildings and garages. It is also recognised for its use in residential and industrial settings. Its versatility extends to both indoor and outdoor use, although it is primarily rated for dry locations.
The cable is made up of insulated conductors encased in a protective metallic jacket or sheath. This design provides enhanced mechanical protection and grounding capabilities. The metallic coating offers excellent strength and protection, including resistance to piercing and shearing forces. While the interior wiring can be damaged by ill-placed nails or screws, the interior coatings offer protection from most environmental conditions.
For outdoor use, it is important to note that the cable's sheathing is not inherently moisture-proof. Therefore, for wet locations, PVC-jacketed MC cable with appropriate fittings should be used to ensure compatibility and provide the necessary insulation against moisture.
MC cable is a popular choice due to its durability and reliable performance for electrical wiring. It can also save time and money by eliminating the need for conduit installation in most interior and exterior applications.
