Section 49 – Signals, Lighting and Electrical Systems

Contract. In addition, the Agency may request samples for testing upon delivery of the cable to

the work site, and, at Agency expense, test the samples for compliance with the Contract.

Cables shall only be installed under dry conditions. Each end of the cable shall be properly

sealed against moisture intrusion and shall be protected against damage.

Cable shall be installed in conduit between termination points. Termination points are

identified as controller cabinets, interconnect terminal cabinets, or master controller building. A

minimum of five feet (5’) of slack cable shall be left coiled at each termination point and in each

pull box. The ends of all cables shall be taped and made waterproof by dipping in an approved

sealer prior to being installed in conduit and prior to being left overnight. Unless otherwise

specified or directed by the Agency, splicing of interconnect cable shall not be allowed.

After field testing of the cable by the Contractor, termination of cable will be made by

Agency forces unless otherwise specified.

49-2.08.B Interconnect Cable Testing After Installation

Signal interconnect cable shall be tested in accordance with these Specifications.

The interconnect cable shall be installed and ready for cable testing twenty (20) Working

Days prior to anticipated use of said cable.

Each insulated conductor in each length of completed cable, with all other insulated

conductors grounded, shall have an insulation resistance of not less than the following:

The tests shall be made using a 500-volt megohm meter applied for one (1) minute. The

test may be terminated as soon as the measurement demonstrates that the specified value has

been met or exceeded for a period of one (1) minute.

The direct current (D.C.) resistance of each pair shall be measured by connecting each pair

together at one end of the cable and measuring loop resistance at the other end. The maximum

resistance shall be 0.01012 OHMS per linear foot ±10 percent for a single #20 AWG conductor.

If the cable being tested fails any one or more of the above tests, the Contractor shall

replace the defective cable. No extension of time or compensation will be allowed for

replacement of cable. All tests and corrections of failures shall be documented and shall be

available for future reference.

All electrical tests shall be made after the cable has been installed in the conduit. The

conduit shall also be filled with water.

Wiring shall conform to Section 86-2.09, “Wiring”, of the State Specifications, except that the

first sentence of the last paragraph of Section 86-2.09D, “Splicing”, and the first paragraph of

Section 86-2.095, “Fused Splice Connectors”, shall not apply, and these Specifications.

Conductors shall not be pulled into and through conduits until after pull boxes are set to

grade, drain rock sumps installed, and the conduits bonded and cleaned out with the

appropriate size swab or blown out with compressed air.
