A resistive load is typically an electric baseboard heater. In resistive loads, the amperage remains the same throughout the call for heat. Inductive loads are typically seen in a motor load. The motor will pull a greater amount of amperage to start and then will drop significantly once the motor is running. Inductive loads require a thermostat specifically designed for inductive loads. The higher the temperature, lower the resistance
