e.
Fused Cable Connectors. Provide connector consisting of a line-
side receptacle and a load side plug, each in a molded rubber form
and including crimp-on fittings for the cable ends to accommodate
a 250-volt cartridge-type fuse. Provide fuse with rating
indicated. Provide connectors in kit form properly sized for the
specific cable diameter involved. Completed connection shall be
watertight.

lighting vault. Cable tags shall be stainless steel, bronze, lead strap,
or copper strip, approximately 1.6 mm (1/16 inch) 1/16 inch thick or hard
plastic 3.2 mm (1/8 inch) 1/8 inch thick suitable for immersion in salt
water and impervious to petroleum products and shall be of sufficient
length for imprinting the legend on one line using raised letters. Cable
tags shall be permanently marked or stamped with letters not less than 6.4
mm (1/4 inch) 1/4 inch in height as indicated. Two-color laminated plastic
is acceptable. Plastic tags shall be dark colored with markings of light

used for connections and splices appropriate for the type of cable. Other
types of cable connectors and splices shall be of copper alloys for copper
conductors, aluminum alloys for aluminum-composition conductors and a type
designed to minimize galvanic corrosion for copper to aluminum-composition
conductors. For FAA Type L-824 lighting cable, connectors shall be FAA AC
150/5345-26, Type L-823.
