1726LEAD-IN CABLE

protrusions. Seat loop conductor at bottom of saw slot without damaging loop wire. Before sealing loop conductors, test that impedance from the loop wire to ground is at least 100 megaohms. For each location with inductive loops, submit a completed Inductive Detection Loop & Grounding Test Results form and place copy in controller cabinet. Ensure all loops are included on form. The form is located on the Department’s website. Embed loop conductors in saw slot with loop seala nt. Seal saw slot and dispose of excess sealant in an environmentally safe manner. Between where loop conductor pairs leave saw cut in pavement and junction boxes, twist loop conductor pairs a minimum of 5 turns per foot. Permanently label each twisted pair in the junction box with nylon cable tie using indelible ink. Indicate loop number and loop polarity on the tie. 1725 -4 MEASUREMENT AND PAYMENT Inductive Loop Sawcut will be measured and paid as the actual linear feet of inductive loop sawcut furnished, installed and accepted. No measurement will be made of trenching between edge of pavement and junction box, loop slot sealant, loop wire, conduit and conduit fittings a s these will be incidental to furnishing and installing inductive detection loops. Payment will be made under: Pay Item Pay Unit Inductive Loop Sawcut Linear Foot

LEAD -IN CABLE -1 DESCRIPTION Furnish and install lead -in cable with all necessary hardware to be used in conju nction with, but not limited to, inductive detection loops, pedestrian pushbutton assemblies, APS assemblies or railroad circuitry . -2 MATERIAL Refer to Division 10. Item Section Lashing Wire and Hardware 1098 -7 Lead -In Cable 1098 -10 Wrapping Tape 1098 -7 Furnish m aterial , equipment and hardware under this section that is pre-approved on the ITS and Signals QPL available on the Department’s website. -3 CONSTRUCTION METHODS For underground runs, install lead- in cable in 2 inch non-metallic conduit. For aerial installation, wrap lead -in cable to messenger cable with at least 4 turns of wrapping tape spaced at intervals less than 15 inches or lash lead -in cable to messenger cable with one 360° spiral of lashing wire per 12 inches . Where railroad preemption is required, install lead in cable from signal controller cabinet to railroad company furnished and installed lockable junction box. Splicing of lead -in cable will be allowed only for runs in excess of 750 f eet. Splice lead -in cable in junction boxes or condulets on poles. Test each complete loop system from the controlle r cabinet by using a megger to verify that
