1.36 Remote/Transfer Switch
When the generator is used as a standby power
supply, it must be equipped with a device which
isolates it from the utility’s distribution system.
Failure to isolate the generator from the utility’s
electrical distribution system could cause out-
put from the generator to backfeed into the
utility lines and cause injury or death to utility
workers!
The same is true if using the generator as a back-
up to some other type of power supply system.
A transfer switch is designed to transfer electrical loads
from the normal power source (utility) to the emergency
power source (generator) when normal voltage falls
below a prescribed level.
The transfer switch automatically returns the load back to
the normal source when power is restored back to
operating levels.
When using the generator as a standby or substitute
power supply, make sure the voltage and phase
rotation of the line connections match those of the
utility lines, or of any other power source normally
used. Failure to match phase rotation and volt-
age may cause equipment connected to the gen-
erator to operate incorrectly! This could create
unsafe operating conditions.
Lethal voltage is always present in the transfer
switch once it has been properly installed!
WARNING
Installation of a transfer switch or other type of remote
starting device is the responsibility of the generator user.
Installation of such devices must be performed by a
qualified electrician following all directions supplied by
the manufacturer of the switch. If attaching generator to
a power supply normally serviced by a utility company,
notify the utility company and check local and state
regulations. Familiarize yourself with all instructions and
warning labels supplied with the switch.
