3.5 - �VIRING INSTALLATION <br /> A. Inslall splices and taps that arc com�atiblc with conductor matcrial and that <br /> possess equivalent or better mechanical strength and insulation ralings lhan <br /> unspliced conduclors. <br /> B. Inslall wiring at outlets with at Icast 12 inchcs (300 mm) of slack conductor at <br /> cach outlet. <br /> C. Conncct outlet and component connections to wiring systems .,.id to ground. <br /> T�ighten clectrical connectors and tenninals, according to manufacWrer's <br /> published torque-tightening values. If manufacturer's torquc valucs are not <br /> indicated, use d�ose snecified in UL 486A. <br /> 3.6- GLECTRICAL SUPPORTING DGVICE APPL[CATION <br /> A. Damp Locations and Outdoors: Hot-dip galvanized materials or nonmetallic, <br /> U-channcl system componcnts. <br /> B. Dry Locations: Stcel materials. <br /> C. Support Ctamps for PVC Raceways: Click-type clamp system. <br /> D. Selection of Suppc rts: Comply with manufacturcr's written instructions. <br /> E. Strength of Supports: Adequate to carry present and future loads, times a <br /> safety factor of at lcast four, minimum of?00-Ib (90-kg) dcsign load. <br /> 3.7 - SUP]'ORT INSTALLATION <br /> A. Install support devices to securely anci permanently fasten and support <br /> elcetrical components. <br /> B. Install individual and muitiple race�vay hangers and riscr clamps to support <br /> raceways. Provide U-bolts, clamrs, attachments, and otl��r hardware <br /> necessary for hanger assemblics and for securing hanger rods and conduits. <br /> C. Support parallel runs of horizontal raceways togelhcr on trapeze- or brackct- <br /> type hangers. <br /> D. Size supporls for multiple raceway instaL'ations so capacity can be increased <br /> �y a 25 percent minimum in the Cuture. <br /> E. Support individual norizontal raceways with scparate, malleable-iron pipc <br /> hangcrs or clamps. <br /> P. Install 55-inch- (C-mm-) diameter �r largcr thrcaded steel hanger rods, unless <br /> othcnvise indicatcd. <br /> G. Arrange supports in verlical runs so the weight of raceways and enclosed <br /> conductors is carried entirely by raceway supports, with no weight load on <br /> raccway temiinals. <br /> FL Simultancously install vertical conduclor supports with conductors. <br /> 1.Separately support cast boxes that are threaded to raceways and uscd for fixturc <br /> support. Support shect-metal boxcs directly Gom the building structure or by <br /> bar hangers. If bar hangcrs are used, attach bar to raceways on opposite sides <br /> of the box and supporl the raceway with an approved fastener not more than <br /> 24 inchcs (GIO min) from the hox. <br /> a�S. <br />
