Shielded: Buildings, Interference Shielding
Flexible
Temperature Range: 0° to 165° F
Insulation: PVC Plastic

Also known as plenum cable, this cable is designated CL3P and CMP, so it has flame-resistant, low-smoke insulation and can be used without conduit in duct work and above a drop ceiling. Use it in low-current circuits such as intercoms, speakers, and security systems.

Use unshielded cable in applications where signal interference is not a concern.

Shielded cable has a layer of foil that blocks signal interference from nearby equipment and devices. It has an uninsulated ground wire that is not counted in the number of wires.

Use for panel and equipment (hook-up)
Stranded Wire: Flexible
Solid Wire: Bend and Stay
Temperature Range: -40° to 220° F
Insulation: PVC Plastic

Also known as hook-up wire, this wire is primarily used for wiring electrical panels, lighting, and plant floor equipment. It meets UL 1007, UL 1015, or UL 1569 for appliance wiring.

Stranded wire is flexible, so it’s pliable enough to be pulled around corners. The strand count is the number of strands followed by the size of the individual strand. The higher the number of strands, the more flexible the wire.

Metric wire is also known as Harmonized European Wire and meets HAR H05V-K for size (mm²), material, and voltage. It can also be used on North American electrical panels and machines.
