CODES AND STANDARDS.

The minimum requirements of National Fire Protection Association ( NFPA)
70, National Electrical Code (NEC), and American National Standards Institute (ANSI)
C2, National Electrical Safety Code (NESC), must be met.
1-4.2
Safety is a fundamental system design requirement that is not met simply by
compliance with applicable codes. Safety has to be designed into a system. This
manual establishes design criteria that exceed NEC minimum standards in some areas.
This manual also follows the design criteria established by OSHA for electrical safety.
1-4.3
Electrical safety requirements applicable to the installation and operation of
electrical systems are provided in Air Force Manual (AFM) 32-1185, Electrical Worker
Safety. Additional guidance is provided in Engineer Memorandum (EM) 385-1-1, Safety
and Health Requirements Manual .
1-4.4
The applicable standards and other docum ents, both government and non-
government, that apply to a specific case are referenced in the text and are listed in
Appendix A.
1-4.5
Codes and standards are referenced throughout this manual. The publication
date of the code or standard is not routinely included with the document identification
throughout the text of the manual. In general, the latest issuance of a code or standard

Whenever a standard or code allows an alternative arrangement subject to
the approval of the Authority Having Jurisdiction (AHJ), this authority is delegated to the
individual service (Army, Navy, or Air Force). Also, t his manual applies and
incorporates a large number of detailed electrical standards. Implementation of these
criteria can be difficult for smaller projects , but for larger projects, many of the sections
might be applicable. The AHJ for each command has the authority to interpret the
applicability of the requirements in this manual as necessary.
1-4.6.1 For the Air Force, the AHJ is delegated to the Major Command (MAJCOM),
with the recommendation that it be redelegated to the local Base Civil Engineer (BCE)
as the responsibility of the local inspector. In case of conflict or lack of resolution at the
local level, issues can be elevated through the MAJCOM to be resolved.
1-4.6.2 For the Army, the AHJ is the Headquarters, U.S. Army Corps of Engineers
(HQUSACE), Engineering and Construction Division (CECW-E).
1-4.6.3
