Although not the code ‘boilerplate’ many use, except possibly by A&E firms, one reference in their “Division 16” verbiage (and other CSI sections) is the InterNational Electrical Testing Association standard MTS-2001, Maintenance Testing Specifications for Electrical Power Distribution Equipment and Systems, §4.1 The user shall provide the testing organization with the following: 2. The most current set of electrical drawings and instruction manuals applicable to the scope of work relative to the equipment under test.
A large complication of this mandate is that the drawings may have been provided for original construction, but they become dangerously out of date with {often routine} facility changes. Keeping them current represents significant effort and expense and sometimes only grudgingly revised at the insistence of a captive maintenance crew.
Simply, it is extremely spooky having to work on facility medium-voltage systems using outdated drawings.
