4. GENERAL REQUIREMENTS
4.1 Electrical equipment mounting. The installation of electrical equipment shall be in accordance with figures 2A1 through 2A22. Electrical equipment shall be secured in a manner that it does not come into direct contact with the outer shell plating or ballistic surfaces of the ship. A minimum clearance of 2 inches shall be maintained for inspection and painting. The mounting of electrical equipment on bulkheads subject to condensation, such as the outer surface of refrigerated space boundary bulkheads, shall be avoided. If no other location is feasible, the equipment shall be mounted at least 2 inches clear of such surfaces. Also, cable shall not be mounted in direct contact with such bulkheads, but shall use one of the wet location methods. When such surfaces are insulated, appropriate insulation methods shall be used for both equipment and cable. Where necessary to attach electrical equipment to decks or bulkheads within gun and missile blast areas, such equipment shall be mounted to provide a 2-inch minimum clearance between the structure and equipment, and, moreover, such equipment shall be located clear of areas of maximum expected deflection or whip of bulkhead and deck plating in order to prevent breakage or pulling loose of mounting feet. Composite electrical enclosures shall be mounted in accordance with NAVSEA Standard Drawing 803-6983506.
4.1.1 Installation welding requirements. Unless otherwise specified on the individual figure, the welding of studs, step hangers, tapped pads, mounting pads, extension hangers, and top bracing supports for switchboards shall be in accordance with S9074-AR-GIB-010/278. Pads, studs, and so forth shall be tapped or threaded before being welded to the ship’s structure.
4.1.2 Installation fasteners. Bolts, nuts, machine screws, and flat and lock washers shall be of commercial grade (5 or better) and material specified. One to five (1-5) threads shall project past locking nuts. Threads shall be American-National firm, coarse series Class 2, unless otherwise specified in a ship contract or ship specification. Thread fastenings shall be as specified in FED-STD-H28. Locking devices shall be used for bolts mounting electrical equipment. Through bolts and self-locking nuts shall be used to mount equipment in gun mounts and in battery compartments. When required by local QA, torque seal shall be installed on all bus connections in power panels, load centers, switchboards, and power converters upon verification of torque using a calibrated torque wrench. Switchboards and load centers shall have torque seal on bus to bus connections as well as cable connections (vendor or contractor) to bus work upon verification of torque using a calibrated torque wrench.
4.1.3 Holes drilled in beams. Location of holes drilled in beams for passing cables or securing of supports or equipment shall be on or above the neutral axis.
4.1.4 Malleable iron castings. Malleable iron castings are not approved for any install except as may be noted on the individual figure.

4.2 Switchboard mounting. Switchboard mounting and bracing shall be in accordance with figures 2B1 through 2B6. The base of each unit shall be adequately secured to the foundation and shall be in a level plane (with reference to ship’s baseline) when secure. In order to ensure there is no warping of the switchboard framework or misalignment of component parts of the switchboard, the base of each section shall not be out-of-plane by more than ⅛ inch after installation, with all securing bolts tightened. Switchboards shall be located so that the base of the units can be bolted directly to the deck stiffeners or foundation and not bolted to a thin deck plate. Foundation bolts of the switchboard units shall be fastened to metal whose thickness in the immediate vicinity of the bolts is at least equivalent to the bolt diameter. The addition of pads may be necessary to obtain the required thickness or to compensate for the lack of flanges on the deck stiffeners. The requirements regarding rigidity of the switchboard structure, the requirements for securing the units to the foundation, and for the foundation in the ship for mounting the switchboard are intended to ensure that the switchboard units after installation in the ship will not display unsatisfactory resonant vibrations. If the horizontal vibration of deck-mounted switchboard sections or switchboards exceeds 0.040-inch double amplitude, measured on the framework near the top of the structure, top bracing shall be provided. Rigidity of the braces and their attachments shall be adequate to prevent vibration of the top of the section. Shear bolts may be employed in the braces if provision is made to prevent the brace from striking the section or bulkhead after shearing of the bolt. Horizontal braces are preferred. The angle of inclination of braces shall not exceed 45 degrees from the horizontal. The braces shall possess inherent flexibility in the vertical direction. Top bracing and installation features shall conform to the methods shown in this section. Bolts, nuts, and washers used to fasten the braces to the switchboard frame shall be held captive by suitable means. Unless other means of bracing are provided, sway bracing shall be provided front-to-back on all switchboards and side-to-side on one-section and two-section switchboards.
4.3 Storage batteries and servicing facilities. Storage batteries and service facilities shall be in accordance with figures 2C1 through 2C10, and all batteries shall be valve regulate lead acid (VRLA), unless otherwise approved by NAVSEA 05Z3. The required number of trays or cells shall be connected in series to produce the required voltage. The necessary ampere-hour capacity shall be obtained by the use of the proper size of battery. Batteries may be connected in parallel in order to obtain greater capacities than those available from the largest sized battery. In general, batteries and their applications shall be as shown in table I. Alternative VRLA batteries shall be proposed if technical and economic factors justify their use. All contractor-furnished and Government-furnished batteries shall be maintained by the contractor in accordance with the manufacturer’s instructions during construction of the ship. The contractor shall charge all batteries in accordance with manufacturer’s instructions not more than 30 days before Acceptance Trials (AT). Battery records shall be kept which indicate the battery function, the Navy type designation, the specification type, the initial charging date, and the dates of subsequent charges, and date and type of any other maintenance actions.

NOTES: 1. Location of mounting holes to be templated from unit being installed. 2. Small holes can be drilled into GRP panels with a sharp, twist-type drill bit. Prick punch to center drill bit.
Larger holes can be drilled with a hole cutter. When drilling holes for “blind fasteners”, a drill stop should be utilized to prevent drilling through the entire panel. When using a hole cutter, first drill through one face sheet, and from the opposite side of the panel, use the pilot hole from the first cut to drill the second face sheet. This method will help avoid panel delamination and high pressure plastic laminate (HPPL) chipping.
3. When cutting and drilling GRP panels, care must be taken to provide adequate ventilation and dust collection. Eye and ear protection and the use of a dust mask is recommended. Caution: if any signs of allergic reaction appear when working with GRP panels, work should stop immediately.
4. Some chipping and cracking of the HPPL may occur when cutting or drilling GRP panels. This degradation of the panel, while unavoidable, must be kept to a minimum so as not to degrade the holding capacity of fasteners or take away from the finished appearance of the panel. In many cases, keeping the drill bits and blades sharp, and using masking tape over the area to be cut or drilled, will keep degradation of the panel at a minimum. If chips and cracks propagate out beyond where the mounting hardware ends, the damage will be noticeable and will require cosmetic repair. In some cases, through-type fasteners may dimple the panel. This condition is acceptable as long as there is no cracking of the panel face.
5. GRP panels are easily scratched, punctured, and scorched by hot work. Care should be taken when working on or close to these panels.
6. For weight limitation of equipment installed on GRP panels, see figure 2A24.

Fastener selection (size) for installation of electrical equipment/foundations to GRP bulkheads/panels Procedure for selecting fastener size and type:
1. Establish correct E, H, L, and Wp per pair of bolts: E = Horizontal distance (inches) from BHD to equipment CG (taken from vendors drawings) H = Vertical distance (inches) between the pair of bolts Wp = Weight (pounds) of equipment acting through each pair of bolts (Wt ÷ number of bolt pairs) L = Horizontal distance between the extreme pair of fasteners
2. Locate correct “E” and “H” values on the “E” and “H” scales shown in table 2A25-I. 3. Make a straight line connecting these points. 4. Where the line made in step 3 crosses the “K” scale shown in table 2A25-I, make a horizontal line all the way
to the right side of the chart. 5. The vertical lines located under each detail represent different ranges of weight that the vertical pair of
fasteners can support. If the horizontal line made in step 4 crosses these vertical lines at values greater then the Wp found in step 1, the fastener detail can be used. In the event that the Wp required exceeds the Wp available on the chart, a pedestal foundation should be considered.
6. If more than one detail will work, the final choice will depend on such factors as available inventory, size of existing mounting holes on equipment, type of space where the equipment is located, and the required finish on the opposite face of the bulkhead.
7. “L” is a function of the number of pairs as shown: No. of pairs “L” 2 0.5H 3 0.75H 4 1.0H
Example Equipment: Feeder distribution box weight Wt = 20 lbs., Height = 14", Width = 13", Depth = 8" Mounting data: Four holes – 17⁄32" dia, 10" (vertical), 9" (horizontal) 1. E = 4 (vendor data), H = 10, Wp = Wt ÷ number of bolt pairs = 20 ÷ 2 = 10 lbs. 2. A straight line connection of E = 4 and H = 10 results in a “K” value of 0.4. 3. A horizontal line drawn from a 0.4 “K” value to the right end of the chart shows that Method 2A-24-1 meets
the requirement.

LEGEND: P - Plugs R - Receptacles
(See figures 2E13 and 2E17)
NOTES: 1. Typical shore power installations for submarines are shown on figures 2E13 and 2E14. 2. Reference should be made to MIL-STD-3007 for typical shore power installations for shore activities. 3. In-line connector installations in accordance with figure 2E17 are used to connect cable assemblies to shore
power plugs. For ease of handling, approximately 10' of THOF-500 cable (15' of THOF-500 cable for submarines) is used for each plug assembly and approximately 150' of THOF-500 for each cable assembly. In-line connectors shall not be used in lieu of a splice of short run cables. Further, in-line connectors may be omitted in favor of a continuous length of cable.
4. Typical shore power installations for surface ships are shown on figures 2E1 through 2E13. 5. Portable shore-to-ship power cables are the responsibility of the shore activity. Portable ship-to-ship or ship-
to-shore cables onboard ship (tenders, repair ships, etc.) are the responsibility of the ship. Splicing of shore power cables is not recommended. If they cannot be avoided, splices and cable jacket repair should be in accordance with the hot splice vulcanized neoprene method described in the Civil Engineering (Naval Construction and Battalion Center, Port Hueneme, CA 93043) Technical Note TN No. N-1503.
6. Provide ungrounded electrical power at the ship’s shore power connection. Power shall be ungrounded from a dedicated transformer secondary serving only the ship and no industrial grounded type loads. The transformer amphere rating is not to be demanded or have a diversity factor applied.
7. Voltage shall not exceed the steady state voltage, ±5 percent, as measured at the ship’s main switchboard, i.e., for a 450-volt nominal ship system the allowable range is 427.5 to 472.5 volts.
8. Current rating requirement shall be achieved via multiple 400-amp shore power cabling circuits. 9. Install safety devices at dockside capable of automatically maintaining services during power surges and
equipped with circuit breakers to de-energize the electrical power during overloads. A 400-amp circuit breaker (100 KAIC rating) shall be provided for each portable shore power cable circuit serving ship. Ensure circuit breaker KAIC rating equals or exceeds (450 volt) transformer and cabling system capability.
10. Portable shore power cabling and connectors serving ship shall have a total current carrying capacity equal to or exceeding the specified shore power current requirements.
11. Type and condition of portable cabling and connectors shall be in accordance with (MIL-STD-2003-2) figure 2E1.
12. Spliced portable cabling is not to be used. 13. All portable cable circuits are to be of equal lengths (within 10 percent). 14. Cabling shall not be allowed to droop into river/sea. 15. Route excess lengths of portable cabling along length of pier and not in coils. 16. Post safety barriers at ship and shore connections. 17. Connect the portable shore power cabling and connectors to the ship. 18. Comply with the ship's polarity requirements. 19. Shore power cables shall be wrapped with protective covering at locations where chafing may occur. 20. PE-stamped power system one-line diagram shall be reviewed/accepted by government electrical engineer
prior to award of contract or connection of ships power to commercial facilities. The drawing is to show both permanent and portable conductors (size/type), switchgear bus ratings, other disconnects, pier connections, circuit breaker ratings, or other features from utility (source) to ships terminals.

NOTES:
1. Portable shore power cable jumper assemblies are a NATO requirement. They are furnished onboard ships to connect to shore cable assemblies in foreign ports or in places where the proper plugs are not available. Normally, the supply activity provides both the cable assembly and the appropriate plugs.
2. Stowage facilities shall be furnished for these assemblies. 3. Install a crotch boot and tubing in accordance with figure 2E17. 4. The NATO required adapter cables should not include in-line connectors. 5. Jumper cables for in-service vessels may be Type THOF-400. However, there shall be no mixing of jumper
cable sizes for each installation. For submarine applications, THOF-400 cable shall not be substituted for THOF-500 cable.

Step 4 – Cable scraping and cleaning: Thoroughly scrape and roughen the outside insulation at the conductors and cable jacket with a scraper. Coarse file or emery cloth for a length to be potted to ensure adhesion with the potting compound. Abrade the rear face of the insert (bus lug side) and the inside surface of the plug in the same manner. Clean abraded area with a lint-free cloth wetted with acetone or methyl ethyl ketone, and allow to dry. Note: Avoid touching or handling of roughened area to eliminate any contamination of surface.
Step 5 – Potting: Slide plug housing over cable and assemble as follows (see illustration 7):
a. Position insert on the bus lugs so index keys fit in their respective slots. b. Apply a light coat of non-insulated lubricant (not silicone grease) to the threads of the 21 pins and install
through the insert so lugs and insert are “locked” together. Lockwashers and flat washers are used with each pin. Flat washers are installed next to the insert. NOTE: Do not over-tighten pins (30 inch-pounds maximum) as they are copper.
c. Install 21 sleeves, chamfer facing out, by snapping them onto the ball-tipped pins (see note 4). d. Install sleeve retainer plates (4 screws each). e. Attach insert to plug housing with eight screws, the index pin, and hole pattern. Assure proper position.
Assure that the eight screws are tight prior to potting. FIGURE 2E15. Termination and potting ship-or-shore power plug MIL-C-24368/1 - Continued.

MIL-STD-2003-2A(SH) APPENDIX E
129
Notes and installation instructions: 1. Clean cable jacket and conductor insulation. First slide tubing over individual conductors and shrink in place
(prior to removal of insulation for crimping). Next slide crotch boot over cable conductors and cable jacket. Press firmly into crotch of conductors and shrink on place (Method 1A-6-1).
2. Shrink on the materials shall be as follows: 2E171-1 Crotch boot Part 1A62-II of Section 1, Group A 2E171-2 Tubing (27" long) M23053/15-104-0 of SAE-AMS-DTL-23053/15 2E171-3 Boot 1/
2E171-4 Kit 2/
1/ Boot, Part 2E171-3 shall be either a heavy duty tubing or a molded boot as shown below. Either part shall have adhesive on the internal wall which meets the adhesive requirements described in Section 1, Group A. Material for the tubing shall meet the performance requirements of SAE-AMS-DTL-23053/15 Class 1. Material for the molded boot shall meet the performance requirements of SAE-AS81765/1.
Expanded Recovered
2/ A kit shall contain: 1 crotch boot (2E171-1), 3 tubing (2E171-2), 3 boots (2E171-3), 1 abrasion device, and pertinent installation instructions.
3. Shrink part by applying heat, using a hot air blower or other heat source. Minimum recovery temperature is 350 °F. As heat is applied, move heat source back and forth over part to be shrunk. For crotch boot and tubing, shrink from center to ends to avoid trapping air. When part has recovered enough to assume the configuration of the item covered and excess adhesive appears at the ends, discontinue heating. Additional heat will not make the part shrink more tightly.
4. Crimp using T&B die no. 94H or equivalent. 5. Shore facilities may utilize available commercial single- or three-phase in-line connectors to facilitate the
shore power connection to ship. Type of connectors used shall be determined by the responsible shore facility. For non-MIL-Spec in-line connectors, installation methods shall be in accordance with manufacturer’s instructions.

MIL-STD-2003-2A(SH) APPENDIX E
131
NOTES: 1. Where receptacles are potted by a manufacturer to a short length of cable, splice shall be in accordance with
MIL-STD-2003-1. For greater accessibility, splice may be located below deck. Ship’s cable may be terminated and potted directly onto the receptacle as shown on figure 2E16 by the installing activity.
2. For suitable cable support, see MIL-STD-2003-4. 3. Access to terminal, boxes, and receptacles shall be provided. 4. Protective enclosure is required to provide protection and personnel safety and shall be of a tightness required
per compartment location. Proper gasketing and drainage for condensation shall be provided for watertight enclosures.
5. Six no. 20 AWG wire leads, 36" long are provided with each switch marked with circuit identification and wire size (1-20, 2-20, etc.). A heat shrinkable tubing (in accordance with SAE-AMS-DTL-23053/4, Class 2) shall be installed over the wire leads between the switch and connection box.
6. Opening of cover or unlatching of plug activates the shunt trip of circuit breaker, opening the breaker to “trip” position. Cover must be closed or plug latched before circuit breaker can be closed.
7. See MIL-DTL-16036 for wiring of the indicator lights. The alternate connection of the indicator lights as shown in MIL-DTL-16036 can be made when crimping the conductors at the cable splice. Flush mounting of indicator lights is preferred for greater protection (see detail “A”, figure 2E9).
8. A handle locking bracket shall be installed when receptacles are furnished without brackets. 9. Deck or bulkhead cable penetrations shall be in accordance with MIL-STD-2003-3.
