CMulti-wire Branch Circuit

Wiring

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.
