PART 3 - EXECUTION
3.1 RACEWAY APPLICATION
A. Outdoors:
1. Exposed: Rigid steel or IMC.
2. Concealed: Rigid steel or IMC.
3. Underground, Single Run: RNC.
4. Underground, Grouped: RNC.
5. Connection to Vibrating Equipment (Including Transformers and Hydraulic, Pneumatic,
Electric Solenoid, or Motor-Driven Equipment): LFMC.
6. Boxes and Enclosures: NEMA 250, Type 3R.
B. Indoors:
1. Exposed: EMT.
2. Concealed: EMT.
3. Connection to Vibrating Equipment (Including Transformers and Hydraulic, Pneumatic,
Electric Solenoid, or Motor-Driven Equipment): LFMC.
4. Damp or Wet Locations: Rigid steel conduit.
5. Boxes and Enclosures: NEMA 250, Type 1, except as follows:
a. Damp or Wet Locations: NEMA 250, Type 4, stainless steel.
C. Minimum Raceway Size: 3/4-inch trade size.
D. Raceway Fittings: Compatible with raceways and suitable for use and location.
1. Intermediate Steel Conduit: Use threaded rigid steel conduit fittings, unless otherwise
indicated.
2. PVC Externally Coated, Rigid Steel Conduits: Use only fittings approved for use with
that material. Patch all nicks and scrapes in PVC coating after installing conduits.
E. Install nonferrous conduit or tubing for circuits operating above 60 Hz. Where aluminum
raceways are installed for such circuits and pass through concrete, install in nonmetallic sleeve.
F. Do not install aluminum conduits embedded in or in contact with concrete.
3.2 INSTALLATION
A. Keep raceways at least 6 inches away from parallel runs of flues and steam or hot-water pipes.
Install horizontal raceway runs above water and steam piping.
B. Complete raceway installation before starting conductor installation.
C. Install temporary closures to prevent foreign matter from entering raceways.
D. Protect stub-ups from damage where conduits rise through floor slabs. Arrange so curved
portions of bends are not visible above the finished slab.
BICKFORD OF CARMEL, IN 12/12/2012
RACEWAYS AND BOXES 16130 - 7
E. Make bends and offsets so ID is not reduced. Keep legs of bends in the same plane and keep
straight legs of offsets parallel, unless otherwise indicated.
F. Conceal conduit and EMT within finished walls, ceilings, and floors, unless otherwise
indicated.
1. Install concealed raceways with a minimum of bends in the shortest practical distance,
considering type of building construction and obstructions, unless otherwise indicated.
G. Raceways Embedded in Slabs: Install in middle 1/3 of slab thickness where practical and leave
at least 2 inches of concrete cover.
1. Secure raceways to reinforcing rods to prevent sagging or shifting during concrete
placement.
2. Space raceways laterally to prevent voids in concrete.
3. Run conduit larger than 1-inch trade size parallel or at right angles to main reinforcement.
Where at right angles to reinforcement, place conduit close to slab support.
4. Change from nonmetallic tubing to Schedule 80 nonmetallic conduit, rigid steel conduit,
or IMC before rising above the floor.
H. Install exposed raceways parallel or at right angles to nearby surfaces or structural members and
follow surface contours as much as possible.
1. Run parallel or banked raceways together on common supports.
2. Make parallel bends in parallel or banked runs. Use factory elbows only where elbows
can be installed parallel; otherwise, provide field bends for parallel raceways.
I. Join raceways with fittings designed and approved for that purpose and make joints tight.
1. Use insulating bushings to protect conductors.
J. Tighten set screws of threadless fittings with suitable tools.
K. Terminations:
1. Where raceways are terminated with locknuts and bushings, align raceways to enter
squarely and install locknuts with dished part against box. Use two locknuts, one inside
and one outside box.
2. Where raceways are terminated with threaded hubs, screw raceways or fittings tightly
into hub so end bears against wire protection shoulder. Where chase nipples are used,
align raceways so coupling is square to box; tighten chase nipple so no threads are
exposed.
L. Install pull wires in empty raceways. Use polypropylene or monofilament plastic line with not
less than 200-lb tensile strength. Leave at least 12 inches of slack at each end of pull wire.
M. Telephone and Signal System Raceways, 2-Inch Trade Size and Smaller: In addition to above
requirements, install raceways in maximum lengths of 150 feet and with a maximum of two 90-
degree bends or equivalent. Separate lengths with pull or junction boxes where necessary to
comply with these requirements.

RACEWAYS AND BOXES 16130 - 8
N. Install raceway sealing fittings at suitable, approved, and 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:
1. Where conduits pass from warm to cold locations, such as boundaries of refrigerated
spaces.
2. Where otherwise required by NFPA 70.
O. Stub-up Connections: Extend conduits through concrete floor for connection to freestanding
equipment. Install with an adjustable top or coupling threaded inside for plugs set flush with
finished floor. Extend conductors to equipment with rigid steel conduit; FMC may be used
6 inches above the floor. Install screwdriver-operated, threaded plugs flush with floor for future
equipment connections.
P. Flexible Connections: Use maximum of 72 inches of flexible conduit for recessed and
semirecessed lighting fixtures; for equipment subject to vibration, noise transmission, or
movement; and for all motors. Use LFMC in damp or wet locations. Install separate ground
conductor across flexible connections.
Q. Surface Raceways: Install a separate, green, ground conductor in raceways from junction box
supplying raceways to receptacle or fixture ground terminals.
R. Set floor boxes level and flush with finished floor surface.
S. Set floor boxes level. Trim after installation to fit flush with finished floor surface.
T. Install hinged-cover enclosures and cabinets plumb. Support at each corner.
3.3 PROTECTION
A. Provide final protection and maintain conditions that ensure coatings, finishes, and cabinets are
without damage or deterioration at time of Substantial Completion.
1. Repair damage to galvanized finishes with zinc-rich paint recommended by
manufacturer.
2. Repair damage to PVC or paint finishes with matching touchup coating recommended by
manufacturer.
3.4 CLEANING
