    Power Schematic

    They changed this from 2+2 to 3+1 but same qty of circuits. Any idea what the qty means? Thanks.

    perhaps it is not a qty but a reference to schematic details number 3 and 1.

      If I remember correctly 2+2 means 4 circuits and 2 neutrals, 3+1 is 3 circuits with 1 neutral and a separate circuit and neutral.

        What Rob said: change from two 3-wire MWBCs to one 4-wire MWBC and one 2-wire circuit.
