DISTRIBUTION SYSTEM MAINTENANCE

Inspection and maintenance of all distribution system components should be scheduled and conducted as outlined in NAVFAC P-322, Inspection for Maintenance of Public Works and Public Utilities, Volume I, and Inspection Guides-Electrical, Volume II. Maintenance and testing of transformers are covered in NAVFAC MO-200, Facilities Engineering Electrical Exterior Facilities. Any inspection and maintenance of, or close to, electrical wiring, equipment, or apparatus, are dangerous. It is vital that all personnel who make such inspections or perform such maintenance know and observe all the prescribed safety precautions. Electrical accidents, like other types of accidents, do not just happen but are the direct result of carelessness or failure to observe safety precautions.

ADVANCED BASE PLANNING

You, as a First Class Construction Electrician within the NCF, may be called upon to assist in the planning and construction of an advanced base. In this section we will discuss the layout of a facility within a component of the Advanced Base Functional Component (ABFC) System and how it fits in with the overall structure of an advanced base. For a more detailed breakdown of Facilities Planning Guide, NAVFAC P-437, and the Advanced Base Functional Component (ABFC) System, refer to NCF First Class Petty Officer, NAVEDTRA 10601. Your primary task as a First Class Construction Electrician will be to install and maintain the electrical system needed by your command to complete its assigned mission.

In Facilities Planning Guide, NAVFAC-437, Volume I, Part 2, you will find facility drawings, indexed by facility number and a DoD category code. Each drawing is a detailed construction drawing that describes and quantifies the facility required to complete it. These predesigned facilities give the planner alternatives for satisfying contingency requirements when a call out of a complete component is not desired. Remember that a "component" is defined as a grouping of personnel and material that has a specific function or mission at an advanced base, whether located overseas or in CONUS, and a component is supported by facilities, which, in turn, are

 

 

 

 

 

 

 

supported by assemblies. Figure 5-20 shows the electrical plan for a 60-bed mobile hospital, component M8E. Within this component, there are several facilities. Figure 5-21 shows all the facilities you will need to construct component M8E (Hospital 60 Bed Mobile). When you are assigned the task of constructing an advanced base using the ABFC system, your ability to read prints and use logic is basically the only requirement other than the components, facilities, and assemblies you will need. The prints give you a basic idea of how this particular advanced base component is to be layed out. Figure 5-22 shows facilities 811 10AU, 811 10AV, 811 10AW, and 811 10P, but, according to figure 5-21, the only facility drawing that you will need for this particular component is 811 10AU. Figure 5-23 shows one assembly (32601), which, along with six others, makes up facility 811 10AU.

NCF First Class Petty Officer, NAVEDTRA 10601, describes how assemblies can be broken down even further by NSN numbers; as shown in figure 5-24.
