NOTE − Electric Heat Circuit Breakers are sized for 240VAC operation. Electric
heaters operating at voltages other than 240VAC may require the factory installed
circuit breaker be replaced with a field installed circuit breaker. See Maximum
Overcurrent Protection column in the Electric Heat Tables to determine if a circuit
breaker change is required.
