Voltmaster Engine-Driven Generators
Emergency circuit isolation
To address the possibility of overloading the generator, the building
may be wired so emergency circuits are grouped together, rewired
to a separate junction box, and connected to the generator through
a manual transfer switch.
The emergency circuit should be configured so it does not exceed
the ampere rating of the generator. The transfer switch must have
an ampere rating equal to that of the emergency circuit.
Total circuit isolation
If the emergency circuits are not or cannot be wired together in a
separate junction box, you will have to select the circuits and
appliances to be powered by the generator. Caution must then be
used to prevent overloading the generator.
The transfer switch must have an ampere rating equal to that of the
normal incoming utility service.
