CONNECTION

w

Before the generator can be connected to a build-

ing’s electrical system, a licensed electrician must

install an isolation (transfer) switch in the build-

ing’s main fuse box. The switch is the connection

point for generator power and allows selection of

generator or main line power to the building. This

will prevent the generator from charging the main

power line (backfeeding) when the main power

supply has failed or has been turned off for line

repair. Backfeeding can electrocute or injure line

maintenance personnel. Also, generator and build-

ing electrical system damage can occur when nor-

mal operating power returns if unit is used without

an isolation switch.
