TRANSFER SWITCH
The generator neutral is bonded to ground when shipped from the factory. The bonding
plate will need to be removed when the unit is used as a standby power supply. Installation
should be in compliance with the National Electrical Code (NEC), state and local regulations.
When the unit 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.
