Power Wiring Interconnections
All wiring must be the proper size, properly supported
and protected by conduit. All wiring should be done per
applicable federal, state and local codes, standards and
regulations. Obey wire type and torque specifications printed
on the terminal blocks and neutral/ground connector.
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.
Complete the following connections between the transfer
switch, main distribution panel, utility power and generator.
Use installer-supplied 300VAC or greater wire that complies
with Table 310.16 in the National Electric Code. Apply the
necessary correction factors and wire size calculations.
NOTICE Improper installation can cause damage to the
circuit boards and shorten their life. Installing circuit
boards in live circuits will damage the board and is not
covered by warranty. ALWAYS disconnect ALL sources of
power prior to servicing.
•
Remove all power prior to installing this equipment.
Failure to do so could cause internal damage to the board
when making electrical connections.

Turn off utility power to the standby generator and
transfer switch.
1. Set generator's circuit breaker to OFF (open) position.
2. Set generator's system switch to OFF position and
remove 15 Amp fuse from system control panel.
3. Turn off utility power to the standby generator and
transfer switch.
WARNING Battery posts, terminals and related
accessories contain lead and lead compounds, chemicals
known to the State of California to cause cancer and
reproductive harm. Wash hands after handling.
4. Connect utility service to transfer switch's utility
disconnect circuit breaker terminals marked
"UTILITY CONNECTION".
5. Connect utility service neutral to transfer switch
neutral terminal.
6. Connect main distribution panel feeder
conductors to transfer switch terminals marked
"LOAD CONNECTION".
7. Connect main distribution panel neutral conductor to
transfer switch neutral terminal.
8. Connect main distribution panel ground conductor to
transfer switch "GND" terminal.
Assure grounding electrode conductor is connected and
bonded per applicable federal, state and local codes,
standards and regulations.

9. Connect copper feeder conductors from transfer switch
breaker "GENERATOR CONNECTION" terminals to
generator circuit breaker LINE1 and LINE2 terminals.
Each conductor must pass through hole of current
transformer before making connection.
10. Plug current transformer leads into "CT1" and "CT2"
