Main and branch electrical circuit breaker testing

Would you be so kind as to forward this question to our membership.
1) Does anyone have an annual or any routine program for Main andBranch electrical breaker testing.
2) If yes how often and down to what breaker size do you test.
3) Does anyone have a program that includes anything more then visualor thermal imaging inspections.
Reason for asking, I recently read where a hospital was cited underImmediate Threat to Life and automatic Preliminary Denial ofAccreditation; for not testing it's main breakers. This is not somethingwe have done in the past and will be implementing starting this year.
