SECTION 14 − GENERATOR POWER GUIDELINES

The views in this section are intended to be representative of all engine-driven welding generators. Your unit may differ from those shown.

14-1. Selecting Equipment

gen_pwr 2012−03 − ST-800 577

Generator Power Receptacles
− Neutral Bonded To Frame

3-Prong Plug From Case
Grounded Equipment

2-Prong Plug From Double
Insulated Equipment

Be sure equipment has double
insulated symbol and/or word-
ing on it.

Do not use 2-prong plug un-
less equipment is double in-
sulated.

Always ground generator frame to
vehicle frame to prevent electric
shock and static electricity hazards.

Also see AWS Safety & Health Fact
Sheet No. 29, Grounding of Portable
And Vehicle Mounted Welding Gen-
erators.

Equipment Grounding Terminal (On
Front Panel)

Grounding Cable (Not Supplied)

Metal Vehicle Frame

Connect cable from equipment ground
terminal to metal vehicle frame. Use #8
AWG or larger insulated copper wire.

Electrically bond generator frame to ve-
hicle frame by metal-to-metal contact.

Bed liners, shipping skids, and
some running gear insulate the
welding generator from the vehicle

frame. Always connect a ground
wire from the generator equipment
grounding terminal to bare metal on
the vehicle frame as shown.

Use GFCI protection when operat-
ing auxiliary equipment. If unit does
not have GFCI receptacles, use
GFCI-protected extension cord. Do
not use GFCI receptacles to power
life support equipment.
