How frequently should circuit breakers be tested for proper operation?

Testing circuit breakers annually is recommended because it allows for a regular check of their functionality and reliability without being overly burdensome. Circuit breakers play a crucial role in protecting electrical systems from overloads and faults, and testing them at least once a year helps ensure they will operate correctly when needed.

Annual testing provides an opportunity to identify any signs of wear, deterioration, or internal faults that may not be visible during routine inspections. This proactive approach increases safety and can prevent potential electrical failures or hazards.

Some establishments may have more stringent testing requirements based on local regulations or specific industry standards, but annual testing is commonly recognized as an effective frequency for most situations.
