Abstract
A system and method for an LCDI power cord and associated circuits is provided. The system and method include energizing shielded neutral wires and shielded line wires and monitoring the energized shields for surges, e.g., arcing, detected by a Leakage Current Detection Circuit (LCDC) and/or voltage drops, e.g., shield breaks, detected by a Shield Integrity Circuit (SIC).
