Installation
8 Integrated Load Center Owner’s Manual
Conductor sizes must be adequate to handle the
maximum current to which they will be subjected, based
on the 167 °F (75 °C) column of tables, charts, etc. used
to size conductors. All installations must comply with
national, state, and local codes. It is the responsibility of
the installer to perform an installation that will pass the
final electrical inspection.
NOTE: If aluminum conductors are used, apply corrosion
inhibitor to conductors. After tightening terminal lugs,
carefully wipe away any excess corrosion inhibitor.
Tighten terminal lugs to the torque values as noted on the
inside of the door.
All power cables should enter the switch next to the
service disconnect circuit breaker terminals. Standard
terminal lugs on the service disconnect are solderless,
screw-type.
Connect power source and load conductors to clearly
marked terminal lugs on the ILC as follows:
• LOAD leads: Connect to individual branch circuit
breaker terminals.
• NORMAL (UTILITY) Source Leads: Connect to service
disconnect circuit breaker.
•
STANDBY (EMERGENCY) Source Leads: Connect to
service disconnect circuit breaker.
Connecting Start Circuit Wires
On-Site Generator Connections
Connect suitable, approved wiring to transfer switch
terminals 178 and 183 (see chart below). Route these
wires through suitable, approved individual conduit and
connect to 183 and 0 (178) terminals in the connection
(lower) panel of the generator set. See Figure 3-2 .
Closure of wire 178 and 183 circuit by switch circuit
action must result in generator engine cranking and
startup.
Recommended wire gauge sizes for this wiring depends
on the length of the wire, as recommended below:

CAUTION
Equipment damage. Verify all conductors are tightened
to the factory specified torque value. Failure to do so
could result in damage to the switch base.
