PART 3 EXECUTION

3.1 INSTALLATION

A. General:

IHS Georgeville Wastewater System Upgrades SECTION 26 05 33 - PAGE 8 7/13/18

1. Install electrical raceways and fittings as shown in accordance with the manufacturer’s written instructions, the applicable requirements of the NEC, and in accordance with recognized industry practices to ensure that products serve the intended function.

Complete electrical raceway installation before starting the installation of wire and cable.

B. Conduit Size:

1. Minimum conduit size for power wiring shall be ¾”, except that 3/8” flexible metallic conduit may be used for fixture whips. Maximum conduit size for EMT shall be 2”.

Minimum conduit size for control wiring shall be ¾”. Minimum conduit size for voice/data wiring shall be 1”.

C. Rigid Steel and Intermediate Metal Conduit:

1. Use rigid steel or intermediate metal conduit to run all electrical raceway systems where exposed to weather; in damp or wet locations; where subject to physical damage; and where cast in concrete walls or floors slabs which have waterproof membranes and where cast in masonry walls. Use rigid steel or IMC conduit for all exposed feeders. IMC conduit shall not be used in sizes larger than 4”. Use threaded type couplings and fittings. Split type couplings and fittings are not acceptable. The interior of all buildings shall be considered a damp or wet area.

D. Liquidtight Flexible Metal:

1. Use liquidtight flexible metal conduit and fittings for all motor connections, and for other electrical equipment connections where subject to movement and vibration and when subject to one or more of the following conditions: (1) exterior locations, moist or humid atmosphere where condensation can be expected to accumulate; (2) corrosive atmosphere, subject to water spray; subject to dripping oil, grease or water. Install internal ground wire in flexible conduit with grounding bushings. Maximum length shall be 6’0” and minimum length shall be 3’0”.

E. Rigid Nonmetallic:

1. Use PVC conduit directly buried in earth, concrete encased, cast in concrete slabs, and where subject to corrosive environment. PVC may be used for all raceways on the interior of the building, which do not contain 480 volt conductors or motor feeders. Use Schedule 40 where direct buried and Schedule 80 where exposed, with size adjusted to have same fill area as if Schedule 40 were used.

3.2 INTERIOR CONDUIT SYSTEM:

A. Ground all metallic conduit in accordance with the requirements of the latest edition of the

NEC.

B. Install all conduit as a complete system without conductors, continuous from outlet to outlet and from fitting to fitting. Make up threaded joints of conduit carefully in such a manner as to ensure a tight joint. Field-cut threads shall be cold-galvanized after cutting. The entire conduit system shall be secured at all joints and boxes in such a manner that each system shall be electrically continuous throughout. Fasten the entire conduit system securely into position. A run of conduit between outlet and outlet, between fitting and fitting, or between outlet and fitting shall not contain more than the equivalent of four quarter bends, including those bends located immediately at the outlet or fitting. Install approved expansion fittings in all conduit runs as specified in paragraph 3.2.P.

C. Ream all ends of conduit properly to remove rough edges. Whenever a rigid steel or IMC conduit enters a switchboard, panelboard, enclosure, or box it shall be securely fastened by the use of a locknut inside and outside and an approved insulating bushing shall be installed.

Insulated grounding bushings shall be installed on all conduits without ground conductors and where required by NEC Article 250. Lay out and install all conduit systems as to avoid all other services or systems, the proximity of which may prove injurious to the conduit or the wires or conductors which the conduit confines.

IHS Georgeville Wastewater System Upgrades SECTION 26 05 33 - PAGE 9 7/13/18

D. Conceal conduit systems in finished areas. Concealed metallic conduits shall be run in a direct manner, basically parallel to, and at right angles with the lines of the building, and with as long a bend as possible. Conduit may be exposed in mechanical rooms and where otherwise shown or indicated. On exposed systems, run the conduit parallel or perpendicular to the structural features of the building and rigidly support with malleable iron conduit clamps at intervals as required by NEC, or on conduit racks, neatly racked and bent in a smooth radius at corners insofar as practicable. All bends shall be field-made using an approved bending machine designed for the purpose, or using standard ells having a radius not less than that required by the National Electrical Code, and with approved fittings or connectors.

All bends shall be free from dents or flattening.

E. All conduit shall be run without traps. Where traps are unavoidable, a junction or pull box shall be placed at the low point. Metallic conduit systems, which are exposed to the weather or water, shall be made watertight. As soon as conduit has been permanently installed in place, conduit shall be capped or plugged with standard accessories. All metallic conduit shall be swabbed after plaster and drywall is finished and dry.

F. Support exposed raceway or grouped concealed raceways on galvanized channel using compatible galvanized fittings (bolt, beam clamps, and similar items) and galvanized threaded rod pendants to secure raceway to channel and channel to structure. Support single conduit runs using a properly sized galvanized conduit hanger with galvanized closure bolt/nut and threaded rod. Support flexible conduit on maximum 4-1/2’ centers and within one foot (1’) of boxes. All raceway support system materials shall be galvanized and manufactured by Kindorf, Unistrut, Superstrut, Caddy, or Spring Steel Fasteners, Inc.

Provide chrome or nickel-plated escutcheon plates on all conduit passing through walls and ceilings in finished areas.

G. Make all joints and connections to ensure mechanical strength and electrical continuity. PVC conduit shall be joined, or have fittings attached, by using a fusing (solvent) compound recommended by and applied as instructed by, the conduit manufacturer.

H. Run conduit to avoid proximity to heat producing equipment, piping and flues, keeping a minimum of 8” clear. Whenever possible, install horizontal raceway runs above water piping.

Unless shown otherwise, do not install conduit horizontally in concrete slabs without written approval. All roof penetrations shall be made in adequate time to allow the roofer to make proper flashings.

I. Carefully review architectural, structural, mechanical, plumbing, and electrical Drawings and place boxes and conduit to avoid conflicts with structural members or other general construction.

J. Conduit larger than ¾” shall not be embedded in structural slabs without prior written permission from the Engineer. Conduits embedded in structural slabs shall be installed in the middle of the slab below the top and above the bottom reinforcing steel. Maintain a minimum concrete coverage of one (1”) except where penetration is made.

K. Furnish sleeves for timely placing in construction for all conduit passing through concrete walls, partitions, beams, floors, and roofs while same are under construction.

L. All conduit passing through the housing on connected equipment, shall pass through a cleanly cut hole protected with an approved grommet.

M. Metallic conduit installed below grade shall have its entire length painted with two coats of protective finish unless encased in concrete. Each coat shall consist of 5mils of PPG “Coat Cat Epoxy Coating” applied in accordance with the manufacturer’s recommendations. The entire length of metallic conduit, including fittings, shall be protected to a point 6” above finished grade (or concrete slab).

N. Coordinate locations of raceways in fire rated partitions so as not to affect the fire rating of the partition. Notify the Engineer in writing where additional construction is required to maintain the partition fire rating.

IHS Georgeville Wastewater System Upgrades SECTION 26 05 33 - PAGE 10 7/13/18

O. Install expansion fittings in all conduit as follows:

1. All conduits crossing building expansion joints; unless some other form of thermal expansion compensation is approved in writing by the Engineer,

2. All conduit straight runs in excess of 200’, and 400’ centers in all longer conduit runs.
