Wanco Two-Bearing Belt-Drive 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 ampere rating must be equal to the ampere
rating of the normal incoming utility service.
Recommended practices
1. Installation of the outdoor connection box and manual transfer
switch must be performed by a licensed electrician or electrical
contractor. A typical installation with an outdoor connection box,
cord set, and manual transfer switch is illustrated in Figure 3-7.
2. To prevent possible overloading of the generator due to immediate
demand for a large amount of power, turn off all lights and
appliances that were on before the utility power failure.
3. Use a connection box and cord set to connect your electric circuits
to the 240-volt receptacle on your generator.
4. Start the generator, then move the manual transfer switch to the
generator position. Turn on vital items, such as lights, being careful
not to exceed the output capacity of the generator.
5. When the utility power is restored, move the manual transfer switch
to the off position, shut down the generator, then move the switch
to the normal position. Your electric circuits are now being powered
by your utility.
6. Disconnect the cord set from the connection box and generator.
When the engine cools down, service the engine and place the
engine and generator back into storage.
