PANEL BOARD ENCLOSURE

The standard switch enclosure is a National
Electrical Manufacturer's Association (NEMA) 1 type.
NEMA 1 type enclosures primarily provide protection
against contact with the enclosed equipment and
against a limited amount of falling dirt.
1.6

SAFE USE OF PANEL BOARD

Before installing, operating or servicing this equip-
ment, read the SAFETY RULES (inside front cover)
carefully. Comply strictly with all SAFETY RULES to
prevent accidents and/or damage to the equipment.
Generac recommends making a copy of the SAFETY
RULES and post them near the transfer switch. Also,
be sure to read all instructions and information
found on tags, labels and decals affixed to the equip-
ment.
Three publications that outline the safe use of trans-
fer switches are the following:
• NFPA 70; National Electrical Code
• UL 1008, STANDARD FOR SAFETY-AUTOMATIC
TRANSFER SWITCHES
• UL 67, STANDARD FOR SAFETY-PANEL BOARDS
2.1

INTRODUCTION TO INSTALLATION

This equipment has been wired and tested at the fac-
tory. Installing the switch includes the following pro-
cedures:
• Unpacking the ILC.
• Mounting the enclosure.
• Connecting power source and load leads.
• Connecting any auxiliary contact (if needed)
• Installing/connecting any options and accessories.
• Testing functions.
2.2

UNPACKING

Carefully unpack the transfer switch. Inspect closely
for any damage that might have occurred during
shipment. The purchaser must file with the carrier
any claims for loss or damage incurred while in tran-
sit.
Check that all packing material is completely
removed from the switch prior to installation.

Section 2 — Installation
Generac ILC Type Transfer Switch
Attach any lifting device to the lifting eyes on top of
the enclosure. DO NOT LIFT THE SWITCH AT ANY
OTHER POINT.
The ILC transfer switch weighs about 300
!
pounds. DO NOT attempt to lift without the
proper equipment.
2.3

MOUNTING

Mounting dimensions for the transfer switch enclo-
sure are in this manual. This enclosure is configured
for wall-mounting. This enclosure is a NEMA/UL 1-
type design, suitable for indoor installation only.
Handle transfer switches carefully when
!
installing. Do not drop the switch. Protect the
switch against impact at all times, and against
construction grit and metal chips. Never install
a transfer switch that has been damaged.
Install the transfer switch as close as possible to the
electrical loads that are to be connected to it. Mount
the switch vertically to a rigid supporting structure.
To prevent switch distortion, level all mounting
points. If necessary, use washers behind mounting
holes to level the unit.
2.4 CONNECTING POWER SOURCE
AND LOAD LINES
DANGER
Make sure to turn OFF both the NORMAL (UTIL-
ITY) and STANDBY (GENERATOR) power sup-
plies before connecting to the power source
and load lines to the transfer switch. Supply
voltages are extremely high and dangerous.
Contact with such high voltage power supply
lines causes extremely hazardous, possibly
lethal, electrical shock.
Wiring diagrams and electrical schematics are pro-
vided in this manual. Power source connections are
made at the service disconnect circuit breakers locat-
ed near the bottom of the enclosure. The individual
load connections will be made at the panel board,
inside the switch enclosure.
2.4.1 2 & 3-POLE MECHANISM
This switch (Figure 2.1) is used with a three phase
system when NEUTRAL is not to be switched. The
two pole switch is similar in construction with the
N3, E3 and T3 pole removed.
