FM 5-422 PDF

Chapter 1. OVERVIEW. ELECTRICAL POWER. Electrical power is an essential element of military operations. Without it, many crucial systems cease to operate. Field Manual (FM) supports engineer, Army, and joint missions throughout full spectrum operations. This FM provides a doctrinal basis for planning. FM The training and experience of prime power NCOs give them an in- depth working knowledge of electrical and electromechanical systems. Each 52E .

Prime power support may extend forward into the corps area at the direction of the theater engineer.

The prime power team is responsible for making the connections to the service equipment. Maintain 25 km of overhead or ground-laid secondary distribution line.

The units’ power-generation capability mf them to The prime power unit also designs temporary, ground-laid distribution systems. It is also useful in identifying potential electrical hazards that could result in damage to connected equipment, electrocution, or electrical fire. Workload estimates for these tasks, which are provided below, are for planning and estimating purposes only and are highly dependent on controlling variables.

Prime power may be supplemented with portable commercial generation equipment when it is available. This mission statement encompasses military operations across the entire continuum of military operations to include disaster relief, humanitarian assistance, and other operations short of war. dm

FM Table of Contents

Engineer prime power units can produce 5-422 quantities of reliable power with their organic kW generators. Army Regulation AR precludes the purchase of nonmilitary-standard generators without the express approval of the program manager-mobile electric power PM-MEP.


Table shows the various possible configurations and the manpower requirements 5-42 continuous operation. During war, the primary objective of prime power operations is to support force sustainment in the communications zone COMMZproviding power generation and power-related technical support to rear-area units, facilities, and activities.

It may also be installed in parallel with a commercial power source.

The prime power unit provides power-related technical assistance to CORs. From the military perspective, electrical power encompasses the entire spectrum of power generation, distribution, and transmission systems that support military operations.

During operations short of war, the primary objective of prime power operations is to provide prime power generation and power-related technical support to forward presence operations, contingency response, ffm disaster relief. Prime power teams are not normally used to perform interior electrical work such as interior wiring.


FM Chptr 1 Overview

Engineer prime power units support sustainment engineering efforts by 5-42 reliable power generation and power-related technical expertise. Chapter 4 contains information on the three modes of power generation. Prime power units have a limited capability to maintain overhead distribution systems. In some cases, nonstandard generators may already be installed as backup.

Prime power personnel can help develop specifications for electrical performance contracts and purchase contracts for electrical material.

The load survey also determines the level of reliability required and identifies any special power requirements or problems. NTG power plants comprise the Army’s family of portable generators larger than kW.


This includes making in-line splices but does not include making connections to distribution transformers, load centers, or service equipment. The completed design includes circuit diagram and site layout drawings or sketches, a complete bill of materials BOMestimated work requirements, and construction time. The gm requirements for construction, maintenance, and repair of nonstandard distribution networks depend on a wide diversity of variables.

Each prime power team is equipped with four kW generators, giving the team a 3-MW peak power-production capability. This function is performed by the vertical construction platoon of the combat-heavy, engineer-battalion line companies and by engineer utilities detachments.

Construct or repair 1, meters of ground-laid primary distribution line per day.

Supported units may use contracting channels to rent or lease these generators. Nonstandard generators 5-42 nonmilitary, commercial-type generators. Prime power units 5–422 these off-the-shelf designs where applicable. Engineer prime power units provide nontactical power generation and power-related technical expertise in support of operations across the continuum of military operations.

A thorough load survey must be completed before work can begin on the installation of a power plant or the design of a distribution system.
