Multiwire branch circuits can be identified by removing the cover on the load
center and inspecting the wiring. Conventional 120 Vac circuits are identified by
a 2-wire-plus-ground (black, white and copper) "romex" for each circuit.
Multiwire branch circuits use a 3-wire-plus-ground arrangement (black, red,
white and copper) for each circuit run.
See Figure 5-4 for an illustration showing the wire used in multibranch
wiring.
