Installing Branch Circuit Conductors

1.

Install properly sized branch circuit conductors into
the transfer switch through the knockouts provided.
Additional knockouts can be made in the field as
needed.

2.

Connect the ungrounded branch circuit conductors
(hot conductors) to a properly sized circuit breaker
approved for use with the transfer switch.

3.

Terminate the neutral conductor and equipment
grounding conductor of the branch circuit at the
neutral/equipment ground terminal bars. 

4.

Size all conductors, raceways, conduits, and
junction boxes, if required, to the applicable NEC
code articles and follow the NEC installation
requirements for the wiring method(s) selected.

NOTE: 

Multi-wire branch circuits must be installed in

accordance with NEC Article 210.4. 

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
disconnect circuit breaker terminals N1 and N2.

2.

Connect utility neutral and ground to the Load
Center Neutral and Ground terminals. Neutral and
Ground terminals on the Load Center are bonded
to each other with a jumper wire.

3.

Connect loads to the Integrated Load Center with
customer-supplied circuit breakers.

4.

See 

Figure 2-1

 and 

Figure 2-3

. Connect generator

to the generator terminals (E1 and E2) on the
transfer mechanism. 

Figure 2-3. Wiring Connections

5.

Connect the generator neutral wire to the top
neutral lug or side lugs on the panelboard.

6.

Connect neutral conductors to the lugs and
terminals along the neutral/ground bars in the
panelboard section of the transfer switch.

7.

Connect a maximum 200A subpanel supply to
lower T1 and T2 connections of 8-position Load
Center Terminals. Connect subpanel Neutral and
Ground to subpanel Neutral and Ground bars.

8.

Connect grounding electrode conductors to the
neutral / ground terminal bars in the panelboard
portion of the switch.
