NTTM NT Test Methods 19.2 CABINETS Cabinets will be provided by the Principal. Install as specified. Refer to standard drawing CS 1554. Cabinets to open away from and aligned square to the road. 19.2.1 Terminal Blocks Provide two terminal blocks for the termination of loop detector feeder cables similar to Clipsal 543. Mount the terminal blocks on the front edge of the cabinet lower shelf. Supply two copies of drawing showing labelled loop layout and terminal blocks. 19.2.2 Switchboard for Solar Power Site Provide and connect a 10 amp on-off switch with the up position as off and clear marks for on and off. Provide a four terminal strip similar to Clipsal 543. Mount and connect voltage regulator as specified. Refer to standard drawing CS 1554. Clearly label terminal strip '+' and '-'. Wire solar panel to terminal strip via switch and regulator. Mount the switch regulator and terminal strip on a non-hygroscopic, non-inflammable base 6 mm Bramite or similar. Separate the switch and strip a minimum of 100 mm. 19.3 CABLING Provide detector loop cable of 30/025 V105 type or similar. Twist loop feeder cable one turn every 20 cm between each loop and junction in the detector pit. Provide loop detector feeder cable of Telcon B3102 CS/NJ/PVC type or similar. Provide Piezo detector feeder cable of 75 ohm co-axial cable type RG59. Provide solar power feed cable of 30/025 V105 type or similar, red and black. Join cables by soldering. Insulate and seal against ingress of water by using mastic filled heatshrink Sigmaform SST 12-04 or similar. Ensure heatshrink covers at least 25 mm of insulation beyond the join. 19.4 CONDUIT Provide and lay 50 mm HD PVC conduit and one P20 white PVC conduit as specified. Allow 25 mm clearance between adjacent conduits. Provide sand cover minimum 100 mm above conduit. Provide electrical marker tape 150 mm below natural surface in conduit trenches.
