In t
he event of an engine add-on request, a change is made from mains to generator supply. The following oc-
curs:
• The MCB is opened
• The GCB is closed
After the engine shed-off request has been issued, a change is made from generator to mains supply. The follow-
ing occurs:
• The GCB is opened

always issues the breaker open command under fault conditions.
