WebDisadvantages of RCD: RCD don’t provide protection against Current Overload. But the main MCB will trip the circuit as RCCD won’t trip in case of a live or neutral faults i.e. short circuit and overload. For this reason, RCBO (MCB with RCD in a single unit) are used for proper protection. WebAn isolator’s major function is to cut out a section of the electrical system that has faults, so that it will be safe to repair. This is also done for inspection and servicing purposes. While a circuit breaker, on the other hand, is like an Automatic Circuit Breaker (ACB). If there’s a fault, it cuts off the entire system.
