Try Military Handbooks MIL-HDBK-1008 and MIL-HDBK-1022 for guidance, at least as to military practice. These have probably been superseded by UFC (Unified Facilities Criteria) but will be helpful in any case. Look at

and browse the library.

Local building code used in your area should be checked. This is generally more of a fire code issue than an electrical code matter.
