PLUMBING EQUIPMENT <br />Section 15450 <br />15-1207 <br />PART 2 - PRODUCTS <br />2.01 ELECTRIC HEAT TRACE <br />A. Acceptable Manufacturers: <br />1. RAYCHEM <br />2. Or equal <br />B. Construction: <br />The self-regulating heating cable shall consist of two (2) 16 AWG (1.2 mm2) <br />nickel -coated copper bus wires embedded in a radiation-crosslinked conductive <br />polymer core. It shall be covered by a radiation-crosslinked, polyolefin, dielectric <br />jacket surrounded by a polymer -coated aluminum wrap, and enclosed in a tinned <br />copper braid of 14 AWG (2.5 mm2) equivalent wire size. The braid shall be <br />covered with a (nominal) 40 mil (1 mm) polyolefin outer jacket, color coded for <br />easy identification. <br />C. Mechanical: <br />The cable shall have a minimum cut -through resistance of 100 Ib (445 N) per the <br />IEEE 515.1 (4.3.3) and CSA 130-03 (6.28) Resistance to Cutting Tests. The <br />cable shall have a minimum impact resistance of 10 ft -lbs per the IEEE 515.1 <br />(4.2.9) and CSA 130-03 (6.2.10.2) Impact Tests. The cable shall have a <br />minimum abrasion resistance of 2500 cycles per the IEEE 515.1 (4.3.4) Abrasion <br />Test. The cable shall withstand a crush resistance of 225 lbs per the IEEE 515.1 <br />(4.2.8) Deformation Test, and withstand a crush resistance of 345 lbs (1500 N) <br />per the CSA 130-03 (6.2.7) Crush Resistance Test. <br />D. Connection Kits: <br />All heating cable connection kits shall be UL Listed, CSA Certified and FM <br />Approved for use as part of the system to maintain hot water temperature. <br />Component enclosures shall be rated NEMA 4X to prevent water ingress and <br />corrosion. Installation shall not require the installing contractor to cut into the <br />heating cable core to expose the bus wires. Connection systems requiring the <br />installing contractor strip the bus wires, or which use crimps or terminal blocks, <br />shall not be acceptable. All connection kits except for the power connection shall <br />be installed under the thermal insulation. The end seal shall use silicone gel. <br />E. Controller: <br />Installed system shall include at least one agency -approved electronic controller. <br />The controller shall not be of line sensing over -limit design. The controller shall <br />be capable of setting different pipe temperatures based on ambient and voltage <br />with 24 hour, 7 day/week programmable options. The controller shall have the <br />energy savings feature of lowering pipe temperature during low use periods and <br />the ability to raise the temperature of the pipes for a programmed interval. The <br />controller shall have BMS interface capabilities to set pipe temperatures and <br />4 <br />
