UL Standard for Safety Leakage Current for Utilization Equipment
|Publication Date:||31 July 2017|
This standard applies to cord- and plug-connected household and similar iutilization equipment (see Definitions, Section 3) typically rated 20 A or less, nominal 50 or 60 Hz, having 3-wire (including equipment grounding conductor) or 2-wire cords, and intended for use on supply circuits not exceeding i300 V to ground.
NOTE: The scope statement in 2.1 does not exclude utilization equipment currently rated higher than 20 A or voltage rated higher than 300 V from referencing this standard.
This standard does not apply to utilization equipment having a grounded connection made at the factory to the neutral terminal. The values in this standard do not provide protection against the minute currents which could cause ventricular fibrillation if applied directly to the heart, as via a heart catheter.
