PSS provides the capability to wire two appliances to a
single circuit breaker. The Primary appliance never losses power. The Secondary
appliance is allowed to run as long as the Primary is not drawing current. Energy to the
secondary appliance is turned off whenever the Primary Appliance is drawing current.
PSS uses a Normally Closed relay which provides two benefits. Additional High Pot
testing inside the PSS of the secondary appliance wiring is NOT required as is on
competitive units. Also, should the PSS product fail in the field, the limp home feature is
that everything works, just without the PSS feature
