Overloading an electrical circuit can lead to severe problems. It is highly probable that you will encounter a circuit overload at least once in your lifetime.
The reassuring news is that most homes are equipped to handle circuit overloads. When overloaded, the circuit will typically trip the MCB (miniature circuit breaker).
The MCB serves as a preventive measure against overloads.
However, it is important to note that not all circuit overloads occur as intended. Whether your home has a modern circuit breaker like an MCB, RCCB, Fuse, etc., or not, you should always make an effort to prevent circuit overloads.
