ELECTRICAL WORK 0 <br />Section 16050 — Page 4 <br />2 <br />c. If splice caps are used, plastic insulating caps may be used. After <br />applying splice caps, use insulating caps rated for the temperatures <br />to which they may be subjected, and install as recommended by the <br />manufacturer. <br />C. Color Coding. <br />1. Color code all secondary branch circuit and feeder conductors as follows: <br />a. Two Wire Grounded System: One black, one white (neutral). <br />b. Three wire, Single Phase, Grounded System: One black, one red, one <br />white (neutral). <br />2. Use green color for any conductor intended solely for equipment grounding, ` <br />unless it is bare. <br />3.02 CONDUIT SYSTEMS <br />A. General Requirements. <br />1. Install an accessible conduit system for connection of all outlet boxes, <br />junction boxes, panelboards, cabinets, gutters, etc. <br />2. All conduit shall be threaded rigid steel, except; <br />a. Electrical Metallic Tubing may be used: <br />1. For exposed work above switch height indoors, except on boiler <br />structures, in refrigerated rooms, or in service tunnels. <br />b. Rigid PVC conduit may be used: <br />1. For direct earth burial outside of building foundations, only where <br />specifically shown on plans, and if buried not less than 24" below <br />the surface. <br />2. For installation under concrete floor slab, which is placed directly <br />on earth or fill, unless otherwise shown on plans. <br />3. For PVC conduits, maintain continuity of conduit system ground by instal— <br />ling copper grounding wire inside PVC conduit, per Title 24, CAC; ground <br />this wire at each accessible location (manhole, pullbox, cabinet, outlet <br />and junction box, etc) and at each termination. <br />B. Bending. <br />1. Bends greater than 300 for PVC conduit systems shall be factory made els. <br />Field bending, not exceeding 30° is allowed for PVC conduit 2" trade <br />size and smaller. Use electric heat box or hot air blower specifically <br />designed for bending PVC conduit; bending by means of open flame, not <br />acceptable. <br />a <br />2. Whenever possible, make bends for exposed stub—ups completely below the <br />surface. Make stubs vertical and arrange neatly. <br />C. Protective Coating: Install protective coating on rigid steel conduits in <br />direct contact with earth or fill of any type, or use rigid steel conduit <br />with factory applied coating. <br />D. Exposed Conduits: Where exposed, install conduits straight and true with <br />respect to each other and adjacent construction. <br />021387:cw MAR 702 <br />
