How Do You Wire A Double Pole Thermostat?

0

Double-pole thermostats are used to control line voltage — electrical power to heating devices. Line voltage is the electricity that comes from the main circuit breaker or fuse panel. When wiring these devices, typically there are two values for line voltage, 120 VAC and 240 VAC. The lower value, 120VAC, is found at the common wall outlet. The higher voltage, 240 VAC, is generally used for providing power to electrical hot water heaters and baseboard heaters. Baseboard heaters will most often use a two-pole line voltage thermostat to control the on and off operation of the heater. Observe the rear of the double-pole thermostat. There are four screws for the electrical connections. Two of the screws are identified as “Line” and the other two screws are labeled “Load.” Typically, the line screw terminals are at the top of the thermostat and the load screws are at the bottom. Each physical side of the thermostat represents one pole of the double-pole internal switch mechanism. Remove all
