D. Provide conduit raceways for all electrical systems as required or as indicated.
PART 2 - PRODUCTS
2.01 CONDUIT REQUIREMENTS
A. Minimum Size: 3/4 inch unless otherwise specified.
B. Rigid steel conduit shall conform to ANSI #C80.1, fittings shall conform to ANSI/NEMA FBI threaded
type.
C. Rigid nonmetallic conduit, PVC SCH40 shall comply with NEMA TC -2 fittings and bodies shall
conform to NEMA TC-3.
D. Secondary service raceways ;
1. Underground from transformer pad to within 5'-0" of building wall shall be PVC SCH40.
2. Underground from 5'-0" away through building wall and or foundations, including all elbows shall
be rigid galvanized steel conduit.
E. Rigid Steel Conduit connectors and couplings;
1. Standard threaded couplings, locknuts, bushings and elbows.
2. Bushings shall have an insulating molded insert and shall be the bonding type.
3. Sealing fitting shall be the threaded cast iron type.
F. Terminations of all metallic raceways shall have insu lated throat.
PART 3 - EXECUTION
3.01 INSTALLATION
A. All conduit and tubing shall run parallel and perpendicular to wall and roof framing members. Conduit
and tubing installed below slabs shall run in straight lines from source to destination.
B. All conduit below floor slab s on grade shall be run in sub -floor below floor, not in floor pour a minimum
of 16” below top of slab . Maximum size raceways in poured concrete structural slabs on the mezzanine
shall be 1" maximum, only with approval of the Construction Representative. All conduits larger than 1"
shall run below the floor structure.
C. Coordinate raceways routing to avoid other trades work.
D. Provide seals when passing from cold to warm environments. Use silicone sealant around boxes and
exterior of raceway and sealing compo und or foam-in-place sealant within raceway. Dux seal will not
be acceptable as sealing material.

E. Conduit joints shall be cut square, threaded, reamed smooth, and drawn up tight. Bends or offsets shall
be made with standard conduit ells; field bends shal l be made with an approved bender.
F. Conduit terminals at cabinets and boxes shall be rigidly secured with locknuts and bushings as required
by the Electrical Code and local authorities. On all conduit 1 -1/4 inch trade size and larger, bushings
shall be insulated with double locknut.
G. Expansion fittings shall be furnished and installed wherever building expansion joints occur. Expansion
joints shall be provided for non-metallic conduit to compensate for thermal expansion and contraction as
recommended by the manufacturer.
H. Underground telephone conduit shall have elongated sweep fittings at base of pole and at building wall.
I. All conduits that are to remain empty shall be provided with a 200 pound test braided nylon line.
J. Install conduit with no more than three 90-degree bends between pull boxes, provide all pull boxes as
required.
K. Install and clean each conduit system completely before installing or pulling conductors.
L. No conduits or cables shall be visible from sales floor above compass o ceilings. Cables and conduits
can only rise up at first partition wall back from compass o ceiling edges or further back.
M. Wiring methods in classified areas:
1. All wiring methods used in Class I, Division 1 and 2 locations must be in full accordance with the
requirements of NEC Articles 501 and 514.
2. Conduit Seals:
a. Conduit seals are required on all conduits that either terminate, route directly through or route
underground beneath a Class I, Division 1 or 2 area.
b. Conduit seals are required within 18 inches of the equ ipment enclosures being served and
within 10 feet of the boundary passing from a classified area into an unclassified area.
c. For underground conduits requiring conduit seals, the conduit is required to be threaded rigid
metal conduit for at least the last 2 feet of the underground run to the conduit emergence from
grade.
N. No conduits shall be routed underground beneath walk -in freezers or coolers.
