22 products
Thermostat wire is electrical cable that connects thermostat controls to a main power circuit. It is typically used in commercial buildings to wire heating and air conditioning controls, as well as bell and fire alarm systems. It consists of multiple insulated conductors encased inside a protective jacket. Each conductor is color coded to help ensure the correct connection to the control board.
Nonplenum-Rated Thermostat Wire
Nonplenum-rated thermostat wire is electrical cable that has been rated for installation in non-air-circulating spaces in buildings, such as closed walls. It is often used to connect thermostat controls to a main power circuit via the ceiling. It is less expensive than plenum thermostat wire, but is more toxic if it burns. It is commonly used in commercial buildings with fewer people present, such as warehouses and distribution centers.

Plenum-Rated Thermostat Wire
Plenum-rated thermostat wire is electrical cable that has been rated to run through the air-circulation spaces in buildings, usually located between the structural and suspended ceiling or under a raised floor. It is used to connect thermostat controls to a main power circuit via the ceiling or floor. It has a flame-retardant jacket that, in the event of a fire, emits fewer harmful fumes and is less toxic than nonplenum-rated thermostat wire.
