    That's exactly what I've got. The connections would be two 10 gauge and one 8 gauge wires per twist nut.
    Compact yes. But does not look neat and clean.

    The labels for L1, L2 are for the AC line side.
    The T1, T2, T3 are for the target machine motor.

    The RPC will pass L1, L2 to T1, T2. The T3 comes from your idler.

    Perhaps the hand wheel has exotic chrome plating.

    I made a hand wheel out of solid 304. A pile of work.

    At least you have three options, make , buy used, or bend.
