2. Exposed: EMT, IMC, or rigid metallic conduit. 3. Concealed: EMT, IMC, or rigid metallic conduit.

4. Slab on grade concrete: IMC, rigid, or PVC. 3.2 INSTALLATION

A. General: Install electrical raceways for all wiring circuits in accordance with manufacturer's written instructions, applicable requirements of NEC, and as follows:

B. Conceal raceways, unless indicated otherwise, within finished walls, ceilings, and floors.

Keep raceways at least 6 inches away from parallel runs of flues and steam or hot water pipes. Install raceways level and square and at proper elevations. Run all conduits in a manner satisfactory to the Architect. On exposed systems, support shall be provided at intervals of 6 feet or closer depending on wiring method. On concealed conduits, support shall be provided at intervals of no more than 8 feet or closer depending on wiring method. No feeder conduit run shall be longer than 80 feet between junction boxes, cabinets or circuit interrupting devices unless there are no direction changes, and only a straight-in-line pull of wire is involved. In such straight-in-line runs between junction boxes, cabinets or circuit interrupting devices, a run not to exceed 120 feet in length may be made.

C. Elevation of Raceway: Install horizontal raceway runs above water and steam piping to

the fullest extent possible.


D. Complete installation of electrical raceways before starting installation of conductors within raceways. All ends of the conduit shall be properly reamed to remove rough edges and whenever a conduit enters a box or other fitting, it shall be securely fastened by the use of a locknut inside and outside of the box or fitting. An approved bushing shall be installed on the ends of all conduit in such a manner as to protect the wire from abrasion. Completed raceways shall be inspected; inspect interiors of raceways, remove burrs, moisture, and dirt and construction debris.

E. Support raceways rigidly by means of straps or hangers best suited for the work.

Conduit shall not be supported from ceiling support system. Multiple runs of conduits shall be racked on trapeze hangers. All support materials shall be rustproof. Perforated tape or wire shall not be used.

SUPPORTS SHALL COMPLY WITH NEW MEXICO ELECTRICAL CODE.

A. Prevent foreign matter from entering raceways by using temporary closure protection. Seal raceways after installation to prevent accumulation of water, dirt and other foreign materials. Conduit in which such accumulation occurs shall be cleaned to the satisfaction of the Architect or replaced.

B. Conduit crossing expansion joints shall be provided with suitable expansion fitting.

C. Protect stub-ups from damage where conduits rise from floor slabs. Arrange so curved

portion of bends is not visible above the finished slab. Conduit crushed or otherwise deformed shall not be installed and shall be removed from the job site without delay.

D. Make bends and offsets so the inside diameter is not effectively reduced. Unless

otherwise indicated, keep the legs of a bend in the same plane and the straight legs of offsets parallel.

E. Use raceway fittings that are of types compatible with the associated raceway and

suitable for the use and location. For intermediate steel conduit, use threaded rigid steel conduit fittings except as otherwise indicated.

F. Run concealed raceways with a minimum of bends in the shortest practical distance

considering the type of building construction and obstructions, except as otherwise indicated.

G. All non-metallic conduit or duct runs shall have a ground bonding conductor, size as

noted or required by NEC. The bond or equipment served shall be bonded to grounding conductor to provide a good ground return path to service panel.

H. Install exposed raceways parallel and perpendicular to nearby surfaces or structural

members and follow the surface contours as much as practical. Paint conduit that will be exposed to the public. Paint shall match surface color.

I. Run exposed, parallel, or banked raceways together. Make bends in parallel or banked

runs from the same center line so that the bends are parallel. Factory elbows may be used in banked runs only where they can be installed parallel. This requires that there be


a change in the plane of the run such as from wall to ceiling and that the raceways be of the same size. In other cases provided field bends for parallel raceways.

J. Join raceways with fittings designed and approved for the purpose and make joints tight.

Where joints cannot be made tight, use bonding jumpers to provide electrical continuity of the raceway system. Make raceway terminations tight. Where terminations are subject to vibration, use bonding busings or wedges to assure electrical continuity. Where subject to vibration or dampness, use insulating bushings to protect conductors.

K. Tighten set screws of threadless fittings with suitable tool.

L. Terminations: Where raceways are terminated with locknuts and bushings, align the

raceway to enter squarely and install the locknuts with dished part against the box. Where terminations cannot be made secure with one locknut, use two locknuts, one inside and one outside the box.

M. Where terminating in threaded hubs, screw the raceway or fitting tight into the hub so the

end bears against the wire protection shoulder. Where chase nipples are used, align the raceway so the coupling is square to the box, and tighten the chase nipple so no threads are exposed.

N. Install pull wires in empty raceways over 4 feet long. Use no. 14 AWG zinc-coated steel

or monofilament plastic line having not less than 200-lb tensile strength. Leave not less than 12 inches of slack at each end of the pull wire. Identify each terminus of pull wire with linen tags marked with complete information as to service and location of the terminus of the line/wire.

O. Install raceway sealing fittings in accordance with the manufacturer's written

instructions. Locate fittings at suitable, approved, accessible locations and fill them with UL-listed sealing compound. For concealed raceways, install each fitting in a flush steel box with a blank cover plate having a finish similar to that of adjacent plates or surfaces. Install raceway sealing fittings at the following points and elsewhere as indicated:

1. Where conduits pass from warm locations to cold locations, such as the

boundaries of refrigerated spaces and air-conditioned spaces. 2. Where required by the NEC.

P. Conduit Stub-up Through Roof: All conduits up through roof shall be properly sealed. Where applicable Contractor shall provide special adapters designed for the specific type of roofing system. See the drawings for special details and instructions for this specific purpose.

Q. Flexible Connections: Use short length (maximum of 6 ft.) of flexible conduit for

recessed and semi recessed lighting fixtures, where EMT and FMC is used, for equipment subject to vibration, noise transmission, or movement; and for all motors. Use liquidtight flexible metal conduit in wet locations. Install separate ground conductor across flexible connections.


R. Conduits above acoustical "lay-in" ceilings shall be anchored to the building structure and not on the ceiling or ceiling support wires. Wire shall not be used to anchor boxes to structure. Junction boxes shall be installed on the structural members and flexible conduit, extended down to light fixtures, length not to exceed 6 ft.

S. Do not install aluminum conduit.

T. PVC externally coated rigid steel conduit: Use only fittings approved for use with that

material. Patch all nicks and scrapes in PVC coating after installing conduit.

U. Lighting fixtures shall not be used for raceways for circuits other than parallel wiring of fixtures.

V. Fire Barriers: Contractor shall be responsible for sealing all conduit penetrations through

fire rated walls and ceilings. The seal shall be acceptable to Architect and maintain the integrity of the wall or ceiling fire rating. 3M brand fire barrier caulk #CP 25 and putty #303 are considered acceptable for this purpose. Refer to Architectural drawings for these locations.
