Circuit Breaker
Resettable circuit breakers transformed electrical safety by ending fuse replacements

What was the main advantage of circuit breakers over fuses that marked a turning point in electrical safety?
Circuit breakers are cheaper and simpler than fuses.
Circuit breakers work by melting a wire to interrupt current flow.
Circuit breakers can be reset and reused, unlike fuses which must be replaced after one use.

Residual Current Detection
Small imbalances in electrical current can instantly save lives by cutting power

Why can't residual-current devices protect a person who touches both the live and neutral wires simultaneously?
Because the device only monitors voltage, not current.
Because the device only works when the circuit is overloaded.
Because the current remains balanced, so the device cannot detect leakage.
