Appendix A
3. Protect against impact and mount the switch vertically to
a rigid support structure. Make sure the switch is level and
plumb.
The transfer switch is an open transition switch. Open
transition switches prevent electrical feedback between the
generator and the utility by only allowing load circuits to be
connected to one power supply at a time.
4. Each wire in the pre-wired transfer switch is color-coded to
easily match circuits in the main panel to their new breakers
in the transfer switch.
5. When three-conductor wiring is used, two 120 volt circuits
will often share the same neutral wire. To avoid overloading
the neutral, either move BOTH of the circuits that share the
neutral or don't move either of them.

6. When moving two circuits with a shared neutral, they should
be connected to adjacent positions (one above the other) in
the transfer switch. That will assure that the two hot wires
are on separate phases and will maintain their relationship to
neutral.
7. Choose a circuit to be backed up and remove the power lead
from the breaker.
8. Using UL Listed wire nuts, reconnect the power lead to a
matching breaker in the transfer switch.
