i. Load transfer.
(1) Each power unit discussed in this lesson is equipped with a
POWER TRANSFER switch. This switch is used to transfer the generator
load from Generator Set Number 1 to Generator Set Number 2 or vice
(See Figure 14.) In some cases, the generator sets may be
referred to as the operating generator set and the standby generator
In either situation, before the load can be transferred from
one to the other, both generator sets must be operating properly.
