Whether you are home or away, the EmPower™ Series
Automatic
Home Generator System provides fully automatic protection from power
outages. Advanced electronics continually monitor utility power.
When an outage occurs, it starts the generator and automatically switches from
utility power to generator power. Electrical power is restored without
effort, in seconds. When utility power is restored, the system senses
it, transfers service back to the utility, shuts down the generator and
resumes monitoring. It's all automatic. No worries, no hassles.
Assembled in the USA. Vanguard engine is made in JAPAN.

Automatic Transfer Switches
Fully Automatic
All of our switches monitor utility and generator voltages and will
automatically connect to the appropriate source of power. The 100 amp
and 200 amp switches are capable of "whole house" power transfer in
residential and small business applications. For whole house
applications the switch amp rating must equal or exceed the utility service
rating. If feeding a sub-panel the switch must equal or exceed the
sub-panel rating.
Safety Features
All switch models are solenoid-operated from utility or generator inputs and
contain electrical interlock switches to eliminate the possibility of
dangerous back feed to utility during an outage. Switches are listed to
UL Standard 1008.
