Difference between circuit breaker and isolater?

Question

Accepted Answer

Circuit breakers protect circuits from overloads and short circuits, while isolators physically disconnect circuits for maintenance or repair.

Circuit breakers automatically trip when there is an overload or short circuit to protect the circuit.
Isolators are manually operated switches that physically disconnect a circuit for maintenance or repair.
Circuit breakers are designed to interrupt current flow during a fault condition, while isolators are used to isolate a circuit for safe maintenance work.
Circuit breakers are typically found in electrical panels, while isolators are often located near equipment for easy access during maintenance.
Both circuit breakers and isolators play important roles in ensuring electrical safety and preventing accidents.
