Answer
Trip switches, also known as circuit breakers, are safety devices housed within electrical panels, consumer units, or fuse boxes. They automatically disconnect the power supply when they detect electrical faults, such as short circuits, earth faults, or faulty appliances, thereby preventing potential hazards. Various types of trip switches include:
- GFCI (Ground Fault Circuit Interrupter): Detects minimal current leaks to earth, offering protection against electric shocks.
- MCB (Miniature Circuit Breaker): Protects against line-to-neutral shorts and significant line-to-earth faults.
- RCD (Residual Current Device): Similar to GFCI but operates at a higher current threshold, providing shock protection without guarding against short circuits or overloads.
- RCBO (Residual Current Breaker with Overload): Combines the features of RCD and MCB, offering comprehensive protection.
Regular maintenance and prompt replacement of faulty trip switches are essential to ensure electrical safety.
