Generac Power Systems PowerMaster™ Load Shedding Device Model 5239 The PowerMaster™ is a load shedding device that allows a home owner to operate two large electrical loads instead of being limited to only one such as a central air conditioner and an electrical hot water heater. When the priority load is running, the PowerMaster will lock out the other piece of equipment, keeping it from turning on until the demand is satisfied for the priority load. After the demand is satisfied, the PowerMaster will allow the secondary load to come on line and operate. Powermaster 0177330SBY.pdf (powerequipmentdirect.com) Show more
