This is a specialized low-voltage cable designed for control circuits in HVAC systems, thermostats, and other power-limited applications. Its "plenum" rating signifies it is engineered to meet strict fire safety standards for use in air-handling spaces within buildings. The 18-8C indicates it has 8 conductors, each 18 American Wire Gauge (AWG).
The "Plenum" rating is crucial because it means the wire is designed with a special jacket that is fire-resistant and produces minimal smoke and toxic fumes in the event of a fire. This is a critical safety requirement for cables installed in air-handling spaces (plenums) to prevent the rapid spread of fire and harmful smoke throughout a building.
This wire is primarily used in plenum spaces without conduit for power-limited circuits. Common applications include thermostats, air conditioning and heat pump systems, bell and alarm systems, signal systems, doorbells, and remote control units.
"18" refers to the American Wire Gauge (AWG) of each conductor, indicating its thickness. "8C" means the cable contains 8 individual conductors (wires) bundled together within the outer jacket. This configuration allows for more complex control signals in advanced HVAC systems.
