Power Outlet Analyzes Electrical Current Usage

Electrical interruptions, or “nuisance trips,” occur when a detector installed behind the wall trips an outlet's electrical circuit when it senses something that could be an arc-fault — a potentially dangerous spark in the electric line. The problem with today's arc-fault detectors is that they often err on the side of being overly sensitive, shutting off an outlet's power in response to electrical signals that are actually harmless.
