Leakage Current AN-113. WHAT IS LEAKAGE CURRENT? Leakage current is the current that flows through the protective ground conductor to ground. In the absence of a grounding connection, it is the current that could flow from any conductive part or the surface of non-conductive parts to ground if a conductive path was available (such as a human ...
LCDI (Leakage Current Detector Interrupter) LCDI’s are permitted for single-phase cord- and plug-connected room air conditioners in accordance with Section 440.65 of the NEC. LCDI power supply cord assemblies use a special cord employing a shield around the individual conductors, and are designed to interrupt the circuit when leakage current occurs between a conductor and the shield.

Leakage current clamp meters are similar to those used for measuring load current, but are more sensitive and therefore more accurate at measuring currents below 5 mA. To determine the Earth leakage on the whole installation, place the clamp around the live conductors for the installation a shown in Figure 2 for single phase, or Figure 3 for three phase installations.
