Installing Breakers

See Figure 2-2. Insert tab on each breaker (A) into the
hook on the bus (B). Push breaker into bus until it snaps
into place.
Figure 2-2. Install Breakers
NOTE: The following 1 in circuit breaker manufacturers
are permitted to be installed: Siemens, Murray, Eaton
BR, and Square D Homeline.

Installing Branch Circuit Conductors

1. Install correctly sized branch circuit conductors into
transfer switch. Knockouts can be made in the field
as needed.
2. Connect ungrounded branch circuit conductors
(hot conductors) to a correctly sized circuit breaker
approved for use with the transfer switch.
3. Terminate neutral
grounding conductor of the branch circuit at neu-
tral/equipment ground terminal bars.
4. Size all conductors, raceways, conduits, and junc-
tion boxes, if required, to the applicable NEC code
articles and follow NEC installation requirements
for wiring method(s) selected.
NOTE: Multi-wire branch circuits must be installed in
accordance with NEC Article 210.4.

Generator Power Supply
DANGER
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.
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 final electrical
inspection.
1. Connect utility supply at utility service disconnect
circuit breaker terminals N1 and N2. Utility supply
lugs are equipped with the 2017/2020 NEC
required finger safe barriers. These barriers must
remain in place after installation.
2. Connect utility neutral conductor to grounded ter-
minal bar. Neutral/grounding conductor terminal
bars are bonded together and to the transfer switch
enclosure through the use of a green main bonding
jumper screw.
3. Connect loads to integrated load center with cus-
tomer-supplied circuit breakers.
4. See Figure 2-1 and
to generator terminals (E1 and E2) on the transfer
mechanism.
