Cast-Iron Pipe Sleeves: Cast or fabricated "wall pipe," equivalent to ductile-iron pressure pipe, with plain ends and integral waterstop, unless otherwise indicated. C. Sleeves for Rectangular Openings: Galvanized sheet steel with minimum 0.052- or 0.138-inch thickness as indicated and of length to suit application. D. Coordinate sleeve selection and application with selection and application of firestopping specified in Division 7 Section "Through-Penetration Firestop Systems." E. Provide a 2” minimum sleeve for each low voltage system. 2.3 SLEEVE SEALS A. Description: Modular sealing device, designed for field assembly, to fill annular space between sleeve and raceway or cable. BICKFORD OF CARMEL, IN 12/12/2012 BASIC ELECTRICAL MATERIALS AND METHODS 16050 - 3 1. Manufacturers: a. Advance Products & Systems, Inc. b. Calpico, Inc. c. Metraflex Co. d. Pipeline Seal and Insulator, Inc. 2. Sealing Elements: EPDM interlocking links shaped to fit surface of cable or conduit. Include type and number required for material and size of raceway or cable. 3. Pressure Plates: Plastic. Include two for each sealing element. 4. Connecting Bolts and Nuts: Carbon steel with corrosion-resistant coating of length required to secure pressure plates to sealing elements. Include one for each sealing element. PART 3 - EXECUTION 3.1 COMMON REQUIREMENTS FOR ELECTRICAL INSTALLATION A. Comply with NECA 1. B. Measure indicated mounting heights to bottom of unit for suspended items and to center of unit for wall-mounting items. C. Headroom Maintenance: If mounting heights or other location criteria are not indicated, arrange and install components and equipment to provide maximum possible headroom consistent with these requirements. D. Equipment: Install to facilitate service, maintenance, and repair or replacement of components of both electrical equipment and other nearby installations. Connect in such a way as to facilitate future disconnecting with minimum interference with other items in the vicinity. E. Right of Way: Give to raceways and piping systems installed at a required slope. 3.2 SLEEVE INSTALLATION FOR ELECTRICAL PENETRATIONS A. Electrical penetrations occur when raceways, cables, wireways, cable trays, or busways penetrate concrete slabs, concrete or masonry walls, or fire-rated floor and wall assemblies. B. Coordinate sleeve selection and application with selection and application of firestopping specified in Division 7 Section "Through-Penetration Firestop Systems." C. Concrete Slabs and Walls: Install sleeves for penetrations unless core-drilled holes or formed openings are used. Install sleeves during erection of slabs and walls. D. Use pipe sleeves unless penetration arrangement requires rectangular sleeved opening. E. Rectangular Sleeve Minimum Metal Thickness: BICKFORD OF CARMEL, IN 12/12/2012 BASIC ELECTRICAL MATERIALS AND METHODS 16050 - 4 1. For sleeve cross-section rectangle perimeter less than 50 inches and no side greater than 16 inches, thickness shall be 0.052 inch. 2. For sleeve cross-section rectangle perimeter equal to, or greater than, 50 inches and 1 or more sides equal to, or greater than, 16 inches, thickness shall be 0.138 inch. F. Fire-Rated Assemblies: Install sleeves for penetrations of fire-rated floor and wall assemblies unless openings compatible with firestop system used are fabricated during construction of floor or wall. G. Cut sleeves to length for mounting flush with both surfaces of walls. H. Extend sleeves installed in floors 2 inches above finished floor level. I. Size pipe sleeves to provide 1/4-inch annular clear space between sleeve and raceway or cable unless sleeve seal is to be installed. J. Seal space outside of sleeves with grout for penetrations of concrete and masonry and with approved joint compound for gypsum board assemblies. K. Interior Penetrations of Non-Fire-Rated Walls and Floors: Seal annular space between sleeve and raceway or cable, using joint sealant appropriate for size, depth, and location of joint. Refer to Section "Joint Sealants" for materials and installation. L. Fire-Rated-Assembly Penetrations: Maintain indicated fire rating of walls, partitions, ceilings, and floors at raceway and cable penetrations.

Roof-Penetration Sleeves: Seal penetration of individual raceways and cables with flexible boot-type flashing units applied in coordination with roofing work. N. Aboveground, Exterior-Wall Penetrations: Seal penetrations using sleeves and mechanical sleeve seals. Select sleeve size to allow for 1-inch annular clear space between pipe and sleeve for installing mechanical sleeve seals. O. Underground, Exterior-Wall Penetrations: Install cast-iron "wall pipes" for sleeves. Size sleeves to allow for 1-inch annular clear space between raceway or cable and sleeve for installing mechanical sleeve seals. 3.3 SLEEVE-SEAL INSTALLATION A.
