PURPOSE.

This UFC provides policy and guidance for design criteria and standards for electrical power and distribution systems.

The information provided here must be utilized by electrical engineers in the development of the plans, specifications, calculations, and Design/Build Request for Proposals (RFP) and must serve as the minimum electrical design requirements. It is applicable to the traditional electrical services customary for Design-Bid-Build construction contracts and for Design-Build construction contracts. Project conditions may dictate the need for a design that exceeds these minimum requirements.

UFC 3-501-01 provides the governing criteria for electrical systems, explains the delineation between the different electrical-related UFCs, and refers to UFC 3-550-01 for exterior electrical system requirements. Refer to UFC 3-501-01 for design analysis, calculation, and drawing requirements.

Onsite generation is not addressed by this UFC.

APPLICABILITY.

The design criteria and standards contained within are the minimum requirements acceptable for military installations for efficiency, economy, durability, maintainability, and reliability of electrical power supply and distribution systems. The criteria and standards herein are not intended to be retroactively mandatory.

Comply with the requirements of NFPA 70 and IEEE C2. Generally, IEEE C2 is the basis for UFC 3-550-01 and NFPA 70 is the basis for UFC 3-520-01. However, there are exceptions to which standard applies to each UFC, including:

• Systems covered by other UFCs, such as airfield lighting and shore power systems.

• Exterior circuits such as lighting and service entrance (overhead and underground), which are covered by NFPA 70.

Comply with UFC 3-560-01 for electrical safety requirements applicable to the installation and operation of electrical systems.

Comply with UFC 4-010-01 and UFC 4-020-01 for security requirements related to exterior electrical distribution systems.
