Residential electrical branch circuit breakers incorporate electronic and electrical technology in Arc Fault Circuit Interrupters that can turn off power to prevent fires if arcing occurs. This ...

When you plug something in at home, you expect the receptacle (aka outlet) to have power. If it doesn’t, you probably know to check and reset the circuit breaker. But what if the breaker didn’t trip?

Imagine you're relaxing in your living room — the lights are on, the TV is streaming your current favorite show, the air conditioner is blowing cool air, and your phones and tablets are plugged in — ...

You may have experienced a short circuit on a 15A to 100A branch circuit that also tripped the main breaker in that same panelboard, resulting in widespread downtime. This short circuit may have ...

Reviewing a typical protective device trip curve (click here to see Fig. 2), it can be divided into three regions. First is the “instantaneous region,” which is the region intended to interrupt ...

When it is about maintaining safety and operational continuity, commercial buildings often prioritise visible systems: fire alarms, emergency lighting, surveillance cameras, and evacuation routes.

To date, all Voltage Source Converters (VSC) used in HVDC networks are incapable of clearing faults on the DC side of the converter. “For most of the situations where such converters have been used so ...
