is required if generator will sup- ply standby power during emergencies or power out- ages.

1Utility Electrical Service

2Transfer 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 12-4).
