This standard applies to cord- and plug-connected household and similar appliances (see Definitions@ Section 3) 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 150 V to ground. This standard does not apply to: a) Appliances having a grounding connection made at the factory to the neutral terminal. b) Electronic measuring instruments not intended for household use. 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. Purpose To minimize the risks associated with the physical reaction of the user@ or burns to the user@ from exposure to leakage currents from appliances under foreseeable use conditions@ this standard provides: a) Leakage current limits; b) Methods@ specifications for measuring equipment@ and test conditions for measurement of leakage currents.
