Is there an industry standard for determining the frequency and type of testing on CBs?

 

There is no industry standard determining the test frequency and type of tests to be performed. These vary by type of CB, manufacturer, and the type of application the circuit breaker is utilized in. It is best to consult the circuit breaker manual to determine proper maintenance and testing schedule. It is common to have 1, 3 or 5, and 10 year maintenance intervals for different types of tests to be performed.
