NOTE: Neutral Bonding - For installations which require
the neutral to be bonded to the ground, this is to be done
on the customer connections terminals inside the
generator. Connect a suitably sized wire from the neutral
bar to the ground bar. This is normally required when the
generator is the source in a separately derived system. It
is not required when the generator is a backup source in
a utility supplied electrical system with a 2-pole transfer
switch. See Figure
