Installation
10 Automatic Transfer Switch Owner’s Manual
Connecting Power Source and
Generator Power Supply
Installation and interconnection diagrams are provided in
this manual.
NOTE: 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.
1. Connect utility supply at the utility service discon-
nect circuit breaker terminals N1 and N2. Follow
torque specifications listed on the circuit breaker.
2. See Figure 3-2 . Connect utility neutral and ground
to the upper neutral (A) and ground (B) terminals.
Neutral and ground terminals are bonded to each
other with a jumper wire (C).
Figure 3-2. Wiring Connections
NOTE: Neutral to ground jumper wire (C) is provided for
use if required by local codes.
3. Connect generator to the generator terminals (E1
and E2) on the transfer mechanism.
4. Connect the generator neutral wire to the lower
neutral lug.
IMPORTANT NOTE: A jumper wire (D) bonds the
upper and lower neutral lugs. NEVER remove this
wire.
5. Connect a subpanel supply to lower T1 and T2
Terminals. Connect subpanel neutral and ground
to lower neutral and ground bars.
Conductor sizes must be adequate to handle the maxi-
mum current to which they will be subjected, based on
the 75 °C column of tables, charts, etc. used to size con-
ductors. The installation must comply fully with all appli-
cable codes, standards, and regulations.
Knockouts into the transfer switch can be made in the
field as needed for entry of power cables and conduit.
Conduit entry shall maintain the proper wire bending
spaces required by CSA C22.1. A barrier provides sepa-
ration between the utility and generator supply conduc-
tors inside the enclosure.
NOTE: The upper panel has a provision for a utility lock
or tag after installation is complete. The service entrance
circuit breaker also has a provision for a locking device.
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 decal located on the inside of the door. After tighten-
ing terminal lugs, carefully wipe away any excess corro-
sion inhibitor.
Electrocution. Turn utility and emergency
power supplies to OFF before connecting
power source and load lines. Failure to do so
will result in death or serious injury.

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.
