    One analysis might be to quantify the energy-passing capability of
    the two alternatives. Electric energy [watts] equals voltage times
    amps [ignoring power factor]. A 30 amp 120v circuit is nominally
    capable of passing 3,600 watts. A 50 amp 240v circuit is 12,000
    watts. Combining two 30 amp circuits [on different legs] gets one to
    7,200 watts; well below the capability of the single 50 amp
    circuit. Using the adapter and putting a load of greater than 7,200
    watts on it might result in popping the ckt breaker on one or both of
    the 30 amp feeder legs. Arild, am I wrong?
    Regards,
    Mike
