The shaft of the standard shall be drilled for <br />no larger that a 1/4 inch hole near the baseplate to provide passage for the bonding <br />conductor. <br />2.11 SERVICE PEDESTALS <br />A. Type III CF service equipment enclosures shall be fabricated from aluminum and shall <br />conform to the fabrication requirements in Section 87-1.03L “Utility Service” of the State <br />Standard Specifications except as follows: <br />1. All exterior seams for enclosure and doors shall be continuously welded by the gas <br />tungsten arc (TIG) process. <br />2. Sealing of the anodic coating shall be in a five (5) percent aqueous solution of nickel <br />acetate (PH 5.0 to 6.5) for 15 minutes at 210 F. <br />B. The anchor bolts for Type III CF service equipment cabinets shall be 5/8 inch diameter, <br />minimum. <br />C. One (1) each Type III CF service equipment cabinets shall have one 200-amp meter <br />socket. See the construction plans for wiring schematic. <br />D. Cabinets shall be prime coated and finished in accordance with Section 91-2 “Painting for <br />Metal”. A graffiti coating acceptable to the City shall then be applied. <br />E. Circuit breakers used as service disconnect equipment shall have a minimum interrupting <br />capacity of 42,000 amperes, RMS, for 120/240-volt services and 30,000 amperes, RMS, <br />for 480-volt services. <br />F. Minimum amperage for sub-circuit breakers shall be as shown on plans. <br />G. Circuit breakers shall be mounted on non-energized clips.
