Residential Transfer Switch Installation Guide
THE AUTOMATIC TRANSFER SWITCH/LOAD CENTER IS NOW INSTALLED!
15 amp breakers utilize 12 gauge wire to allow for easy replace-
ment with 20 amp breakers if required by the installation with-
out the need to replace/upgrade the wire gauge.
If a generator is being installed at this time, proceed to step 15. If a
generator will not be installed at this time, perform steps 11 through
14 to complete the pre-wiring project.
11. Open the outdoor connection box and unplug the 4-pin and 2-pin
connector. Remove the black, white, red, and green wires that
lead from the five foot pre-wired conduit. Make sure the mating
wires from the 30 foot conduit are on the connection box termi-
nal lugs (or ground screw), re-install all washers and nuts and
secure them in place.
12. Remove the lock nut holding the five foot pre-wired conduit
coupling to the outdoor connection box. Slip the lock nut over
the wires and plug, then remove the conduit from the connection
box. Use a knockout plug to close off the opening where the
conduit was removed.
The external connection box may be locked to
ensure safety and to discourage tampering.
13. For pre-existing buildings, switch the service main circuit breaker
back on to provide utility power to the building.
14. Save the five foot pre-wired conduit for re-installation at time
of generator installation. At that time, re-install the conduit by
reversing steps 14 and 15. The grounding strap will also be
installed with the generator. Save this guide for reference at time
of generator installation.
Be sure the service main circuit breaker is
switched OFF at time of generator installation.
This completes the pre-wiring portion of the Automatic Transfer
Switch/Load Center Installation. Proceed with step 15 for generator
installation.

NOTE.
15. Place the generator and mounting pad in the location pre-
pared utilizing the Standby Generator Installation and Owner's
Manuals. Ensure that the distance from the structure (minimum
18" inches) allows for slack inj the five foot pre-wired liquid tight
conduit and that it meets code.
16. Ground unit in accordance with local codes.
The generator mode switch should be placed in the OFF posi-
tion. Generator main line circuit breaker should be switched to
the OFF or OPEN position.
17. Access wiring connections for installation of five foot harness
at the generator. To gain access to wiring connections and the
circuit breaker you must remove the cover plate (black) over
the control module. Remove the two screws retaining the cover
plate. Lift the cover plate up and towards the front of the genera-
tor to remove.
Remove the small silver cap from back of enclosure. Remove
threaded lock nut from conduit coupling (with 90° elbow) and
wires. Feed wires into the hole. Place threaded lock nut over
wires and onto conduit coupling. Tighten securely with screw-
driver and hammer to ensure lock nut is tight. Connect power
leads (red & black) to the circuit breaker lugs. Connect the
neutral wire (white) to terminal bar labeled "Neutral". Connect the
ground wire (green) to terminal bar labeled "GROUND". Connect
sensing wires to terminal strips as follows: Yellow - N1, Yellow -
N2, Blue - T1 / White - 23, Red - 194.
