Appendix C, “Multi-wire Branch Circuit Wiring” supplies
information about Multi-wire Branch Circuit Wiring Precautions
when using stand-alone 120 Vac inverters or generators.
WARNING
A possible fire hazard can exist if 120 Vac only sources (such as inverters and
generators) are wired incorrectly into 120/240 Vac panels containing multi-wire
branch circuits. This section describes how to check for multi-wire branch
circuits in the load center and presents some possible solutions to this wiring
method.
