SECTION 11 − GENERATOR POWER GUIDELINES

.

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

11-1. Selecting Equipment

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
insulated.

!

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)

2

Grounding Cable (Not Supplied)

3

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
welder/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.
