Power Wiring Interconnections

NOTICE Improper installation could 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 generator to OFF position.
• Turn off utility power to the standby generator and
transfer switch.
All wiring must be the proper gauge, 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, neutral/ground connectors, and
installation instructions.
WARNING Shock Hazard. Installing low and high
voltage wire in same conduit could result in death,
serious injury and/or property damage.
• Do not run low and high voltage wire in the same conduit
unless the insulation rating on ALL wiring is rated for
600V. See NEC for more information.
Use installer supplied 300VAC or greater copper wire of a
gauge that complies with the latest version of the National
Electric Code to complete the following connections between
utility power, transfer switch, generator, main distribution
panel, and optional remote modules. Apply the necessary
correction factors and wire size calculations.
1. Set generator's circuit breaker to OFF (open) position.
2. Set generator's system switch to OFF position.
3. Remove 15 Amp fuse from generator control panel.
4. Turn off utility power to the standby generator and
transfer switch.
