Each of the 60Hz single phase equipment circuit breakers energizes one of the dedicated 60Hz single phase receptacles on
the front of the control/distribution center, refer to the Genset Frequency Configuration—60Hz Mode in the Maintenance
and Lubrication section of this manual for 60Hz configuration set-up instructions. Each circuit breaker will independently
trip if an over current condition arises in its dedicated circuit.
Each of the 60Hz single phase equipment circuit breakers incorporates a Ground Fault Circuit Interrupter (GFCI). A GFCI is
a device whose function is to interrupt the electric circuit to a load when a fault current to ground exceeds a predetermined
value, that is less than that required to operate the over current protective device of the supply circuit.
GFCIs are designed to shut off electric power when the current going into the electric equipment does not equal the amount
of current returning to the GFCI. A GFCI interrupts the unbalanced current flow in a fraction of a second, to prevent
electrocution. GFCIs only protect against unbalanced current flow type faults, some current must be returned through
another path for the GFCI to trip. GFCIs do not protect against line to line or line to neutral contact hazards such as result
