Did the circuit breaker trip when it went up from the distribution box
When a breaker detects an abnormal surge, it “trips,” cutting off electricity to prevent potential damage. You can reset the breaker once the issue is resolved. It's working exactly as designed. It's shutting off power because something on that circuit isn't safe. The tripping is a warning signal, not a malfunction. But what's causing it? And more importantly, does it need an expensive fix, or is. The main circuit breaker is designed to protect the electrical system in a building or home from overload and potential fire hazards.

Function of Relay Protection Current Circuit
A current relay is a protective device used to monitor the current flow in electrical systems, like transformers and motors. It serves to guard against issues such as voltage drops, short circuits, and other irregularities in the power supply network. Product Specialist (West Region) for Digital Substation Products at ABB Inc. Previous experience in designing low voltage and medium voltage switchgear, relay panels and custom control panels as an Electrical Engineer at ESSMetron, Denver CO. It functions as a watchdog by constantly surveying multiple system components including voltage, current, frequency, and phase angle. A protective relay is basically an electrical device that detects a fault in a power system and initiates the operation of the circuit breaker to isolate the defective section or component from the rest of the system.
