INSULATED CONDUCTORS <br />Section 16070 <br />15-1207 <br />Branch circuit wiring for receptacle outlets, lighting, control and signal circuits. <br />2. In dry locations as open runs of cable. <br />B. Type MC cable shall have a maximum of five (5) conductors, four (4) current carrying <br />conductors and one (1) equipment ground conductor. Ground conductor shall be internal <br />insulated ground copper conductor. <br />C. Install MC cable in accordance with manufacturer's instructions and in accordance with the <br />C.E.0 Article 334. Follow manufacturer's instructions when connecting the cable to fittings and <br />boxes. Secure connectors to the cable, but not over -tightened. Firmly attached connector to <br />the metal boxes. <br />D. Support and secure cables at intervals not exceeding six (6') feet and within 12 inches of box <br />or fitting using separate metal strap or spring metal clip for each cable. Do not bundle cables <br />together. Do not support cables from raceways or mechanical piping. Do not rest cables on <br />ceiling tiles or allow contact with mechanical piping systems. <br />E. Provide 1/4 inch threaded or solid rod grid, 4 feet on centers, above ceiling spaces for cable <br />support. Use spring metal clip for cable attachment to rod. <br />F. Cable connection to light fixtures: Acceptable to attach cable to fixture support wire using <br />spring metal clip. <br />G. Use steel with insulated throat cable connectors. OZ/Gedney AMC Series or equal. Die cast of <br />pressure cast fittings not permitted. <br />H. Use cable having color coded conductors as noted. Color coded conductor sleeves are not <br />permitted. <br />Provide separate sleeves and/or fire barriers for cable fire wall penetration, unless cable is UL <br />listed for the application. <br />J. MC cable is not permitted for homerun use. Extend cable from junction/wireway box having <br />branch circuits for the immediate area. Use conduit for routing branch circuit conductors from <br />junction or wireway box to the panelboard - locate this box in the approximate geometric center <br />of the outlets served by that homerun. <br />3.3 WIRE IDENTIFICATION: <br />A. Provide wire markers on each conductor in panelboard, gutters, pullboxes, outlet and junction <br />boxes, and at load connection. Identify with branch circuit or feeder number for power and <br />lighting circuits, and with control wire number as indicated on equipment manufacturer's Shop <br />Drawings for control wiring. <br />3.4 TESTING: <br />A. Notify Architect when installed cable is ready to be tested. <br />B. Apply megger tests. Supply labor, materials and test equipment required to perform continuity <br />checks and megger tests. Submit test data for approval. <br />5 <br />
