732.19 wire in breakaway anchors shall be commercially pure lead of thickness 0.030 to 0.042 inches (0.75 to 1.0 mm). 732.19 Cable and Wire. Furnish cable and wire meeting the requirements of Table 732.19-1 and rated at 600 volts with conductors of copper unless otherwise specified. Ensure that the cable or wire jacket is indelibly marked at intervals of not more than 6 feet (2 m) with nomenclature stating the size, the type, the organization specifying the type, and the manufacturer’s name or trademark. Furnish materials according to the Department’s Qualified Products List (QPL). 732.20 Power Service. Furnish risers for power service that are 1 to 1 1/2-inch (25 to 38 mm) diameter conduit and fittings according to 725.04 Furnish weatherheads that are threaded and made of aluminum or galvanized ferrous metal. Include a disconnect switch with enclosure. 732.21 Disconnect Switch with Enclosure. Ensure that the switch enclosure is a UL listed watertight lockable stainless steel NEMA Type 4 supplied with the conduit hubs listed on the enclosure UL label. Furnish an enclosure that contains as a minimum a single-throw, 2 pole, solid neutral, fused safety disconnect switch (or circuit breaker) UL listed as suitable for a service disconnect with a minimum capacity of 30-amperes at 240 VAC. Ensure that the unit can be padlocked in both the “ON” and “OFF” positions. Furnish materials according to the Department’s Qualified Products List (QPL). 732.22 Backplates. Furnish backplates constructed of wrought sheet aluminum, according to ASTM B 209 (B 209M), 6061-T6, .050 inch (1.3 mm) minimum thickness. Backplate base metal shall be anodized to maximize paint adhesion according to Mil-A-8625, Type II or Type I. Furnish backplates painted on both sides with at least two coats of flat black alkyd enamel paint or polyester powder coat (no epoxy) closely matching FED-STD-595b-37038. Furnish a backplate that extends 5 inches (125 mm) beyond the outside of the signal assembly on all sides. The overall outside shape of the installed backplate shall be rectangular. The backplate shall allow no gaps between the backplate and the signal head or between signal sections. A 2- inch (50 mm) wide continuous outside border of yellow or fluorescent yellow reflective sheeting shall be applied to the front face of the backplate. Reflective sheeting shall be Type H or J listed on the Department’s Qualified Products List. All assembly and mounting hardware shall be stainless steel conforming to 730.10. If used, machine nuts shall be thread-deforming or nylon locknuts. Rivets shall not be used for mounting the backplate to the signal head. A minimum of four mounting points shall be used on each signal section for attaching the backplate. Furnish all mounting hardware. 814
