TRANSFER SWITCH

The generator neutral is bonded to ground when shipped from the factory. The bonding
plate will need to be removed when the generator is used as a standby power supply.
Installation should be in compliance with the National Electrical Code (NEC), state and local
When the generator is used as a standby power supply, it must be equipped with a transfer switch which isolates it
from the utility's distribution 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.
FAILURE TO ISOLATE THE GENERATOR FROM THE NORMAL POWER UTILITY CAN
CAUSE POTENTIALLY LETHAL VOLTAGE TO BACKFEED INTO THE UTILITY LINES.
THIS MAY RESULT IN INJURY OR ELECTROCUTION OF UTILITY WORKERS NEARBY.
MAKE SURE THE GENERATOR IS ISOLATED BY A TRANSFER SWITCH FROM ANY
LOCAL UTILITY LINES. THIS ALSO APPLIES IF THE GENERATOR IS BEING USED
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 following all directions supplied by the manufacturer of the switch.
If attaching the generator to a power supply normally serviced by a utility company, notify the utility company and
check state and local regulations. Familiarize yourself with all instructions and warning labels supplied with the switch.
