2)Your Installer will determine if all of the desired back-up loads can be operated by the generator at the same time. If not, you will need to purchase/install PowerPause™ Load Management modules to manage pre-determined loads so as to not exceed the generator capacity.

3)If PowerPause™ Load Management modules are required, determine which appliances will be connected to the PowerPause™ modules (up to six appliances, 240VAC, 50A). Central air condition compressors can be directly connected and controlled by a PowerPause™ Load Management module via the 24 VAC thermostat circuit.

4)Assign a priority to each circuits/appliances by ranking them from most important to least important, with 1 being most important. Keep in mind that less important circuits will be powered infrequently by the generator and possibly not at all if the generator does not have capacity available to start and run the appliance. Complete Table 3.4 below.

For example, let's assume that your first floor central air conditioning system is your most important PowerPause™ Load Management appliance (priority 1), as it is the most important occasionally operating priority load (i.e.: it does not need to operate all of the time, but when there is sufficient generator capacity available, it is the first load desirable to operate). Typically a central AC system will be connected to two circuit breakers: one 15A 1-pole circuit breaker for the air handling unit and one 30A 2-pole circuit breaker for the outdoor AC compressor unit. Only the AC compressor unit should be connected to a PowerPause™ Load Management module in priority position 1; with the air handler continuously connected to generator power, air will continue to circulate within the house.

Continuing with the example, let’s say the second priority appliance is a 30 gallon electric water heater, which will require connection to a PowerPause™ Load Management Module and a PowerPause™ Relay Box. Install the PowerPause™ Relay Box as close to the load center where the 30 Amp 2-pole circuit breaker is located for the water heater.

Typical appliances recommended (OK) to connect to a PowerPause ™ Relay Box:
•	Electric oven	•	Electric clothes dryer	•	Boat lift
•	Electric cook top	•	Well pump	•	Room air conditioner
•	Electric range	•	Fountain	•	Supplemental electric space
• Electric hot water heater		•	Spa equipment		heater
	(tank)	•	Pool equipment
• Instant hot water heater		•	Outbuilding

NOTE: Most central air conditioning compressor units are controller through a 24 VAC thermostat control circuit. If central air conditioning load management is required, interrupt the 24 VAC thermostat control circuit by wiring directly in series with the PowerPause ™ Load Management module.

NOTE: Critical loads that MUST operate when required should NOT be connected to a PowerPause ™ Load Management Module. It is recommended that the generator and transfer switch be sized properly to power ALL critical loads without the need for load management. The PowerPause ™ Load Management Module and Relay Box can and will disconnect power to connected loads without notice and may not re-power the load until utility power is restored.
