4.2 Load Shed Kit
The optional load shed kit disconnects selected loads
before transfer to the emergency source, reducing the
load on the generator set. See Section 2 for descriptions
of the load shed operation during normal operation, test
and exercise.
Transfer switches that are factory-equipped with the
load shed accessory have a letter S at the end of the
model designation. See the model code chart in the
Introduction.
