1.22.4.1. 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. Load terminals L and N are energized by this momentary contact to bring
the generator set on line.

1.22.4.2. 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.
1.22.4.3. There is a transient suppression diode assembly consisting of two diodes (CR2 and CR3) at the load
terminals (+ and -) on MEP-501A. These diodes protect the load circuit from potential damage resulting from cross
connecting the + and - output terminals on the alternator (G2). The diodes prevent damage by only allowing the
current to flow in the generator circuit in one direction.
