Wiring Interconnections
All wiring must be the proper size, properly supported and
protected by conduit.
Complete the following connections between the transfer
switch, main distribution panel, utility power and generator,
as shown on the next page.
High Voltage Wiring
1. Ensure utility power is turned OFF. Connect utility
Service conductors to line side of transfer switch
service disconnect circuit breaker.
2. Connect utility service Neutral conductor to the transfer
switch “NEUTRAL” terminal, if applicable.
3. Connect main breaker panel feeder conductors to
transfer switch terminals marked “LOAD
CONNECTION”.
4. Connect main breaker panel Neutral conductor to
transfer switch “NEUTRAL” terminal, if applicable.
5. Connect main breaker panel Ground conductor to the
transfer switch “GND” terminal.
NOTE: Assure grounding electrode conductor is connected
and bonded per applicable federal, state and local codes,
standards and regulations.
6. Connect generator feeder conductors from the
generator control panel to line side of transfer switch
“GENERATOR” breaker. Each conductor should pass
through hole of current transformer before making
connection.
7. Plug in current transformer leads into “CT1” and “CT2”
on control module.
8. Connect Neutral conductor from the generator control
panel to the transfer switch “NEUTRAL” terminal, if
applicable.
9. Connect generator Ground conductor from the control
panel to the transfer switch “GND” terminal.
NOTE: Assure generator equipment grounding conductor is
connected per applicable federal, state and local codes,
standards and regulations.
10. Connect generator “UTILITY 240 VAC” terminals to
transfer switch “UTILITY 240 VAC” terminals. Use
minimum #14 AWG conductors.
11. Tighten all wire connections/fasteners to proper torque.
See inside transfer switch enclosure for proper torque
values.
Low Voltage Wiring
1. Connect Tx Rx and Tx Rx Ground from the generator
control panel to the GND and T/R on the transfer switch
control board.
2. Tighten all wire connections/fasteners to proper torque.
See inside transfer switch enclosure for proper torque
values.
WARNING
Low voltage wire cannot be installed in same
conduit as power voltage wiring.
• Failure to follow above warning could cause personal injury,
damage and/or malfunction of equipment.
