NOTE: Balance must be maintained when moving  circuit
locations 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 you
are unsure of proper procedure or if your installation
differs from that described in this guide, consult a
licensed professional at this time.

13a. 

Remove the main electrical distribution panel cover.
Remove appropriate size knockout from the bottom
or side of the main panel. (A 2-foot flexible conduit is
pre-wired from the transfer switch with built-in load
center.) Remove threaded lock nut from conduit
coupling.  Feed all wires through knockout into main
panel. Slip lock nut over wires and tighten securely
onto conduit coupling. 

NOTE: Circuits to be moved must be protected by same
size breaker. For example, a 15 amp 120V circuit in
emergency load center will replace a 15 amp 120V
circuit in main panel.

13b.

In your main panel, remove the black (hot) wire from
a circuit breaker that protects a circuit you want to
have powered in the event of a power failure. Wire
nut the black wire to the matching circuit lead wire
from the emergency circuit breaker from load center
in the transfer switch. (All circuit wires are color
coded and labeled for easy identification).  Repeat
this process with remaining circuits to be powered
by the generator. White wires (neutral) in your main
distribution panel should remain connected to
neutral bar. It is not necessary to move them.  The
emergency load center in the transfer switch supplies
the following circuits: (5) 15A/120V, (3) 20A/120V,
(1) 20A/240V and (1) 30A/240V.

14. 

Install the 70 Amp double pole circuit breaker that
you have purchased into main electrical distribution
panel. This circuit breaker 

must be compatible with

your 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 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 double pole circuit
breaker.
