    Doesn't that require cross listing as THWN-2 for wet locations?
    THHN on its own is not listed for wet at all.

    Is this a constant on, dual conversion UPS?
    What is the voltage percentage of the 13th harmonic?
    Would that be one of the main current harmonics from a twelve pulse rectifier load somewhere?
