False Trip
A False Trip is when an electrical circuit breaker or safety switch shuts off power unnecessarily, without any real electrical problem present. It's like a false alarm in a security system. This is a common issue that electrical technicians need to diagnose and fix, as it can cause unexpected power interruptions in homes or businesses. Understanding false trips is important because they can indicate underlying issues with wiring, equipment age, or environmental factors like moisture, even if there isn't an immediate danger.
