Exposed conduit shall be fastened to structures acceptable to the City’s Representative by clamps, straps, or hangers spaced at intervals not more than 10 feet when fastened to steel structures and not more than 7-1/2 feet when fastened to concrete. Do not support or fasten conduit by welding directly to equipment or to the building structure. Do not use C clamps as a permanent method of supporting vertical conduit risers. In conduit runs with expansion joints, install clamps within 3 feet, but not closer than 6 inches, to couplings, boxes, and fittings. Install exposed raceways parallel to or perpendicular to walls and structural members, and parallel to intersections of vertical plans and ceilings. Provide all conduit straps and clamps with base fittings or back plates that provide an air space of 1/4 inch minimum between the conduit run and supporting surfaces. Do not use perforated iron or wood plugs and nailing as methods of attachment. Make fastenings to steel members with granular flux filled welded studs.

C. Locate cable tray supports on centers not greater than 8 feet to ensure a rigid installation. Interconnect sections for a rigid mechanical assembly. Provide cable tray supporting components comprised of clamps, clips, concrete inserts, hanger rods, insulators, racks, frames, trapezes, beams, structural steel clamps, U-bolts, slotted angles and fittings, machine screws, wall anchors, and similar items. Ensure that components of dissimilar metals are compatible with the equipment that they support, such as raceway, cable tray, and cable equipment.

D. In damp or wet locations, do not mount electrical equipment (including boxes, starters, panels, and conduit) so that it touches the walls. Provide 1/2 inch or more of air space between wall and equipment. If strips or channels are used for standoffs, mount them vertically, so they will not collect moisture.

providing Work of this Section shall be incidental to Electrical Work.
