Balance must be maintained when moving circuit loca-
tions from main electrical distribution panel to emergency
load center. Circuit breaker positions alternate buss bars
vertically. Circuits sharing a neutral wire should either be
moved together to adjacent positions in emergency load
center or not moved. If unsure of the proper procedure or
if the installation differs from that described in this guide,
consult a licensed professional at this time.
12a. Remove the main electrical distribution panel cover.
Remove appropriate size knockout from the bottom
or side of the main panel. (A two foot flexible conduit
is pre-wired from the transfer switch with built-in load
center). Remove threaded lock nut from conduit cou-
pling. Feed all wires through knockout into main panel.
Slip lock nut over wires and tighten securely onto con-
duit coupling.
Connection of Emergency Circuits
12a
Circuits to be moved must be protected by same size
breaker. For example, a 15 amp 120 volt circuit in emer-
gency load center will replace a 15 amp 120 volt circuit
in main electrical distribution panel.
12b. In the main panel, remove the black (hot) wire from
the circuit breaker that protects a circuit to be powered
in the event of a power failure. Wire nut the black wire
to the matching circuit lead wire from the emergency
circuit breaker in the load center in the transfer switch.
(All circuit wires are color coded and labeled for easy
identification). UL listed wire locknuts are included in
installation kit. Trace each black (hot) wire connected
and wire nut the white (neutral) wire from the same
Romex cable (circuit) to the matching circuit number
on the white (neutral) wire from the emergency load
center. Repeat for each circuit. Repeat this process
with the remaining circuits to be powered by the gen-
erator.
Both grounded and ungrounded conductors must be moved
to the emergency panel and connected to the new wiring
from the emergency panel using supplied wire nuts.

13. Install the 70 amp double pole circuit breaker; 10, 12,
14, 16, 17 and 20kW units or the 40 amp double pole
breaker; 8kW units (purchased or supplied separately),
into main electrical distribution panel. This circuit
breaker must be compatible with the main electrical
distribution panel. It may be necessary to reposition
remaining circuit breakers or remove circuit breakers
that have been disconnected to accommodate the
insertion of the 70 amp or 40 amp double pole circuit
breaker. Connect white wire to the main distribution
panel neutral bar. Connect solid green wire to main
electrical panel ground bar. Connect the black and red
wires to the 70 amp or 40 amp double pole circuit
breaker. Reinstall the main distribution panel cover.
