UL778中的Dielectric voltage-ithstand：
35.1.1 A pump shall with stand for 1 minute without breakdown the application of a 60-hertz, essentially sinusoidal potential:
a)Between live parts and grounded dead metal and
b)Between the terminals of a capacitor used for radio interference elimination or arc suppression.The test potential shall be as follows:
1 ^7 s8 X: J- h$ E, n* \1)One thousand volts for a nonsubmersible pump rated no more than 250 volts, and no more than 1/2 horsepower(373 watt output).
2)One thousand volts plus twice the rated voltage for a nonsubmersible pump rated more than 250 volts, or more than 1/2 horsepower.
