Residential Transfer Switch Installation Guide
THE AUTOMATIC TRANSFER SWITCH/LOAD CENTER IS NOW INSTALLED!
If a generator is being installed at this time, proceed
to step 19. If a generator will not be installed at this
time, perform steps 14 through 17 to complete the
pre-wiring project.
14. 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 terminal lugs (or
ground screw), re-install all washers and nuts and
secure them in place.
15. 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 must be locked to
ensure safety and to discourage tampering.
16. For pre-existing buildings, switch the service main
circuit breaker back on to provide utility power to the
building.
17. 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 ground-
ing strap will also be installed with the generator. Save
this guide for reference at time of generator installa-
tion.
DANGER
Be sure the service main circuit breaker is switched
OFF at time of generator installation.
This completes the pre-wiring portion of the 100 Amp
Automatic Transfer Switch/Load Center Installation.
Proceed with step 18 for generator installation.

18. Place the generator and mounting pad in the location
prepared in steps one through five.

19. Attach one end of the grounding strap (No. 12 AWG
stranded copper wire) to grounding rod, and the other
end to the grounding lug (located at rear corner of
unit). Make sure the grounding rod and strap are not
exposed above ground level (NEC code applies to
grounding method).
The generator mode switch should be placed in the OFF
position. Generator main line circuit breaker should be
switched to the OFF or OPEN position.
20. Access wiring connections for installation of five foot
harness at the generator. To gain access to wiring con-
nections 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 generator to
remove.
