Extension Cords for Hazardous Locations



Use these cords where ignitable gas and dust may be present. The industry designation is SEOOW, so the inner and outer insulation resists oil.
Hazardous location environmental ratings indicate whether manufacturers have included safety features in products to facilitate their safe use in a hazardous environment. Before selecting a product for a hazardous location, ensure it is rated for your environment. See About Hazardous Location Environmental Ratings.

- Flexible
- Temperature Range:
MC, THHN: 15° to 190° F
MC, XHHW-2: -40° to 190° F - Outer Insulation:
MC, THHN: Aluminum Armor
MC, XHHW-2: Aluminum Armor, PVC Plastic - Inner Insulation:

Also known as metal clad (MC) cable, this cable has metal armor that acts as conduit to protect the building wires. It's often used along the exterior of walls to carry power to outlet boxes. It has a ground wire that is not counted in the number of wires.
Hazardous location environmental ratings indicate whether manufacturers have included safety features in products to facilitate their safe use in a hazardous environment. Before selecting a product for a hazardous location, ensure it is rated for your environment.
Cable with THHN wire stands up to condensation and moisture in basements and other damp environments.
Cable with XHHW-2 wire has a PVC outer jacket over the aluminum armor. You can use it in wet environments where liquid might drip and splash on it. It can also be used for direct burial without a conduit.

Armored Fire Alarm Cable


- Use For: Buildings
- Flexible
- Temperature Range: -10° to 190° F
- Insulation:
Outer: Aluminum Armor
Inner: Nylon Plastic, PVC Plastic
Prevent damage to wires for fire alarm systems, smoke detectors, and other critical circuits with this armored cable. Also known as metal clad (MC) cable, the metal armor acts as a conduit to protect the wires inside. The PVC inner insulation resists flames. Its nylon jacket is low smoke, so it can be used without conduit in duct work, under raised floors, and above a drop ceiling. This cable has a ground wire that is not counted in the number of wires.
Hazardous location environmental ratings indicate whether manufacturers have included safety features in products to facilitate their safe use in a hazardous environment. Before selecting a product for a hazardous location, ensure it’s rated for your environment.
Shielded cable has a layer of foil that blocks signal interference from nearby equipment and devices.
