NETA acceptance and maintenance testing
NETA specifications describe how electrical power equipment is field tested: the acceptance tests before a system is energized and the maintenance tests on interval afterwards. They are what turns an installed switchgear lineup into a lineup somebody is willing to close in on.
Adoption varies by jurisdiction. Confirm the edition your authority having jurisdiction enforces before you run a walk against it.
