Section III: Performance and Sizing
ELECTRIC DUCT HEATER
General Duct Heater Information
Power wiring should incorporate properly sized fuses or motor rated circuit breakers. A disconnect must be tted within
easy access and sight of the unit. Supply voltage must be maintained within +/- 10% of design voltage on both single and
three phase units. Cycles must be within +/- 5% of design. Failure to operate within these ranges can adversely affect
performance, cause failure of the equipment, and may void warranty terms.
