12 SGM-SF code examples: IRC® CHAPTER 38 BRANCH CIRCUIT WIRING METHODS 3802.3 Exposed cable. In exposed work, except as provider in Sections E3802.2 and E3802.4, cable assemblies shall be installed as specified in Sections E3802.3.1 and E3802.3.2. E3802.3.1 Surface installation. Cables shall closely follow the surface of the building or running boards. E3802.3.2 Protection from physical damage. Where subject to physical damage, cables shall be protected by rigid metal conduit, intermediate metal conduit, electrical metallic tubing, Schedule 80 PVC rigid nonmetallic conduit, or other approved means. Where passing through a floor, the cable shall be enclosed in rigid metal conduit, intermediate metal conduit, electrical metallic tubing, Schedule 80 PVC rigid nonmetallic conduit or other approved means extending not less than 6 inches (152 mm) above the floor. E3802.3.3 Locations exposed to direct sunlight . Insulated conductors and cables used where exposed to direct rays of the sun shall be listed or listed and marked, as being “sunlight resistance”, or shall be covered with insulating material, such as tape or sleeving, that is listed or listed or listed and marked as being “sunlight resistant.” E3802.3.4 In unfinished basements and crawl spaces. Where type NM or SE cable is run at angles with joists in unfinished basements or crawlspaces, cable assemblies containing two or more conductors of sizes 8 AWG and larger shall not require additional protection where attached directly to the bottom of the joists. Smaller cables shall be run either through bored holes in joists or on running boards. Type NM or SE cable installed on a wall of an unfinished basement shall be permitted to be installed in a listed conduit or tubing or shall be protected in accordance with Table 3802.1. Conduit or tubing shall be provided with a suitable insulating bushing or adapter at the point the where cable enters the raceway. The sheath of the type NM or SE cable shall extend through the conduit or tubing and into the outlet or device box not less than ¼ inch (6.4 mm). The cable shall be secured within 12 inches (305 mm) of the point where the cable enters the conduit or tubing. Metal conduit, tubing, and metal outlet boxes shall be connected to an equipment grounding conductor complying with Section E3908.13. code examples: IRC® CHAPTER 39 POWER AND LIGHT DISTRIBUTION E3905.1 Box, conduit body or fitting—where required. A box or conduit body shall be installed at each conductor splice point, outlet, switch point, junction point and pull point except as otherwise permitted in Sections E3905.1.1 through E3905.1.6. Fittings and connectors shall be used only with the specific wiring methods for which they are designed and listed. E3905.11 Damp or wet locations. In damp or wet locations, boxes, conduit bodies and fittings shall be placed or equipped so as to prevent moisture from entering or accumulating within the box, conduit body or fitting. Boxes, conduit bodies and fittings installed in wet locations shall be listed for use in wet locations. Where drainage openings are installed in the field in boxes or conduit bodies list for use in damp or wet locations, such openings shall be approved and not larger than ¼ inch (6.4 mm). For listed drain fittings, larger openings are permitted where installed in the field in accordance with the manufacturer’s instructions. E3906.1 Conductors entering boxes, conduit bodies or fittings. Conductors entering boxes, conduit bodies or fittings shall be protected from abrasion. E3908.4 Effective ground-fault current path. Electric equipment and wiring and electrically conductive material likely to become energized shall be installed in a manner that creates a low impedance circuit facilitating the operation of the overcurrent device or ground detector for high-impedance grounded systems. Such circuit shall be capable of safely carrying the maximum ground fault current likely to be imposed on it from any point on the wiring system where ground fault might occur to the electrical supply source. E3909 FLEXIBLE CORDS E3909.1 Where permitted. Flexible cords shall be used only for the connection of appliances where the fastening means and mechanical connections of such appliances are designed to permit ready removal for maintenance, repair or frequent interchange and the appliance is listed for flexible cord connection. Flexible cords shall not be installed as a substitute for the fixed wiring of a structure; shall not be run through holes in walls, structural ceilings, suspended ceilings, dropped ceilings or floors; shall not be concealed behind walls, floors, ceilings or located above suspended or dropped ceilings.
