TP-6335 9/04 Electrical System 13

Section 6 Electrical System

Hazardous voltage.

Can cause severe injury or death.

Operate the generator set only when

all guards and electrical enclosures

areinplace.

Moving rotor.

WARNING

Electrical backfeed to the utility. Hazardous backfeed

voltage can cause severe injury or death. Connect the

generator set to the building/campground electrical system

only through an approved device and after the

building/campground main switch is opened. Backfeed

connections can cause severe injury or death to utility

personnel working on power lines and/or personnel near the

work area. Some states and localities prohibit unauthorized

connection to the utility electrical system. Install a transfer

switch to prevent interconnection of the generator set power

and other sources of power.

6.1 Electrical Connections

Have qualified electricians make electrical connections.

Connections to the load leads, battery, and remote

switch panel complete the installation. To prevent

unintentional starting, make final connections to the

battery only after making all other connections.

The following paragraphs provide details on each

connection. Refer also to the wiring diagram in the

operation manual.

Securely support or harness all wiring to the generator

set to prevent abrasion. Provide additional support for

the wiring to prevent exposure to the exhaust system

and drippage of fuel, oil, or grease. Allow at least a

51 mm (2 in.) clearance between the electrical wiring

and hot exhaust parts. Do not locate the wiring directly

below or near the fuel system parts or the oil-fill tube.

The following paragraphs cover some other points to

consider when making AC load connections.

Note: At the time of installation, make the wiring

connections accessible for inspection and

service.

6.2 AC Load Lead Connections

Routing. Each generator set has four color-coded load

leads. The black leads (L1 and L2) are hot, the white

lead (L0) is neutral, and the green lead is the hazard

ground. See Section 8 for the AC load lead connections.

Route the load leads directly from the junction box to the

vehicle AC circuit or transfer switch connection. Route

the load leads of all installations through flexible conduit

from the generator end bracket to the junction box.

Keep the load lead junction box accessible for service

and inspection.

Note: Keep the load lead circuit away from the

generator fuel and exhaust system components.

Note: Use field-supplied wiring capable of withstanding

temperatures of 75_C (167_F).

Connect the neutral of the AC circuit in the vehicle to

lead L0 (white or gray). If the vehicle uses equipment

ground-type plugs and receptacles (3-pronged),

connect the green wire to the U-shaped pin. On vehicles

that also have provisions for using an outside AC power

source, completely isolate the neutral as well as the hot

(black) leads from the generator set when switching

power to the outside source. See Figure 6-1.
