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 pages.
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.
High Voltage Wiring
1.Ensure utility power is turned OFF. Connect utility feeder conductors to transfer switch terminals marked
“UTILITY CONNNECTION”.
2.Connect utility Neutral conductor to the transfer switch “NEUTRAL” terminal.
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.
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 transfer switch terminals marked “GENERATOR CONNECTION” 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.
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.Using #18 AWG twisted pair conductors, no greater than 200 ft in length, 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.
