Before installing the Reliance Controls transfer switch system, please make a
emergency energy plan that includes which appliances you need during a power
outage. It is highly recommended to “balance the load” between the two phases of
transfer switch, that’s to say, do not connect high-wattage appliances centrally to a
single EP500Pro.
