在UL 8750里面有写"

8.7.1 A cord-connected unit rated for a nominal 250-V or less supply shall be tested in accordance with this section. Leakage current shall not be more than:
a) 0.5 MIU for a two-wire cord- and plug-connected unit,
b) 0.5 MIU for a three-wire (including grounding conductor) cord-and plug-connected portable unit, and
c) 0.75 MIU for a three-wire (including grounding conductor) cord- and plug-connected stationary or fixed unit.
