Have only qualified persons

perform these connections

according to all applicable

codes and safety practices.

Properly install and ground

this equipment according to

its Owner’s Manual and na-

tional, state, and local codes.

Customer-supplied equipment
is required if generator will sup-

ply standby power during

emergencies or power out-

ages.

1 Utility Electrical Service
2 Transfer Switch (Double-Throw)
Switch transfers the electrical load

from electric utility service to the

generator. Transfer load back to

electric utility when service is re-

stored.
Install correct switch (customer-

supplied). Switch rating must be

same as or greater than the branch

overcurrent protection.
3 Fused Disconnect Switch
Install correct switch (customer-

supplied) if required by electrical

code.
4 Welding Generator Output
Generator output voltage and wir-

ing must be consistent with regular

(utility) system voltage and wiring.
Connect generator with temporary

or permanent wiring suitable for the

installation.
Turn off or unplug all equipment

connected to generator before

starting or stopping engine. When

starting or stopping, the engine has

low speed which causes low volt-

age and frequency.
5 Essential Loads
Generator output may not meet the

electrical requirements of the prem-

ises. If generator does not produce

enough output to meet all require-

ments, connect only essential

loads (pumps, freezers, heaters,

etc. − See Section 11-4).
