1.21.4. Output Supply. (Figure 1-8)
1.21.4.1. The generator set is brought on line by placing the ON-OFF load circuit breaker (CB1) in the ON position.
The circuit breaker is a single pole, shunt trip switch with momentary contacts that return it to the neutral, or center
position when the toggle switch is released. An EMI filter (MEP-531A) or load terminals L and N (Mechron 120 VAC
set) are energized by this momentary contact to bring the generator set on line. The GFCI convenience receptacle (J3)
is also energized by ON-OFF load circuit breaker (CB1). The GFCI convenience receptacle (J3) features a ground
fault interrupter which protects the generator set components from inductive current in the ground circuit originating
from the load connected to the GFCI receptacle (J3).
1.21.4.2. Placing the ON-OFF load circuit breaker (CB1) momentarily in the OFF position opens the line to the load
terminals and takes the generator set off line. The ON-OFF load circuit breaker features a diode (CR2) which protects
the generator set components by allowing current to flow in only one direction.
