Are you talking about a post-construction manual checkout procedure (continuity etc?) Or some kind of on-line monitoring/protection in case a fault developes?

Suggestion: Try MCC manufacturers' literature, e.g.

http://www.ab.com

http://www.squared.com

http://www.ge.com

http://www.siemens.de

http://www.alstom.com

http://www.abb.com

http://www.cutlerhammer.com

http://www.seecousa.com/designex600vmcc.htm

etc. for more info.
The troubleshooting of MCC compartments is one of the possible way to fine any problems in the MCC compartments.
