![]() ![]() The JBLM Service Connection Manual is provided here along with the Service Connection Application that must be filled out for each project that connects or effects the electrical distribution system.ĥ. As each project begins, the project manager shall refer to the Service Connection Manual and submit a Service Connection Application to begin the process of coordination. Per the privatization contract, CLP is responsible for design, construction, and connection to the JBLM electrical distribution system. Royanna Jackson 25, Per DA Memo dated April 24, 2018, all utility system infrastructure improvements and additions associated with privatized utility systems are to be accomplished through use of the cognizant Utilities Privatization System Owner, unless an exception has been granted.Ĥ. David Laboy (253) 966-1758, Utilities Branch Chief, Ms. For contract questions, concerns, or interpretations Government points of contact include the Contracting Officer Representative (COR), Mr. Excluded areas include Yakima Training Center and JBLM areas not geographically located near JBLM-Main.Ģ. The electrical utility privatization contract, SP0600-18-C-8327, was awarded through the Defense Logistics Agency (DLA) and is being administered by Directorate of Public Works, Engineering Services Division, Utilities Branch. The primary distribution system includes JBLM-Main, McChord Field, North, and all associated areas. The system point of demarcations are the primary power lines while the secondary lines will remain with the DPW shops. READ FIRST - All JBLM utility distribution system work must be coordinated through the ESD Utilities Branch upon the start of project scoping.ġ. As of 1 July 2019, City Light and Power (CLP) is now responsible for JBLM's Electrical Distribution system and hereby known as the electrical system owners.

These ampacities were calculated as detailed in the basic ampacity paper, AIEE Paper 57-660, The Calculation of the Temperature Rise and Load Capability of Cable Systems, by J. ![]() In Figure B.2(1) through Figure B.2(4), where adjacent duct banks are used, a separation of 1.5 m (5 ft) between the centerlines of the closest ducts in each bank or 1.2 m (4 ft) between the extremities of the concrete envelopes is sufficient to prevent derating of the conductors due to mutual heating. Underground electrical duct bank configurations, as detailed in Figure B.2(2), Figure B.2(3), and Figure B.2(4), are utilized for conductors rated 0 through 5000 volts. Table B.2(11) provides the adjustment factors for more than three current-carrying conductors in a raceway or cable with load diversity. Typical ampacities for conductors rated 0 through 2000 volts are shown in Table B.2(1) through Table B.2(10). ![]()
