About this file
This is a specification document for non-metallic raceways prepared by Volusia County for the Branch Jail Air Handler-Fire Suppression System Removal, Replacement and Upgrade project. The specification, Section 260534, outlines requirements for Schedule 40 rigid polyvinyl chloride (PVC) conduit to be used below grade only, with transition to rigid metal conduit prior to exiting below-grade areas and concrete slabs. All above-grade applications are restricted except for grounding systems, and all stub-ups must utilize rigid steel unless otherwise approved. The minimum conduit size is 3/4 inch, with all fittings, couplings, adapters, and reducers required to match the conduit material and manufacturer. The specified manufacturer is Carlon or owner-approved equivalent, with a minimum five-year manufacturing experience requirement.
Installation requirements mandate compliance with Article 352 of the National Electrical Code and include provisions for factory-made or heat-bent elbows and bends without direct flame application. All non-metallic raceways must include a continuous insulated grounding conductor connected to ground at each end in accordance with NEC Article 250. Joints must be solvent-welded using Rectorseal Gold #844 cement meeting ASTM D2584 standards, with purple-colored primer cleaner applied to prepared surfaces. A continuous six-inch-wide yellow plastic underground utility marker tape must be installed above the full length of underground conduits at a minimum depth of one foot below finished grade and one foot above the conduit. Additionally, contractors must utilize 90-degree elbow fittings in lieu of fabricated sweeps for long sections of installed PVC conduit.

SECTION 260534 RACEWAYS - NON-METALLIC
PART 1 - GENERAL
1.1 SCOPE:
A. This section deals with the materials to be used as raceways where shown on the drawings or specified as non-metallic conduit.
1.2 WHERE USED:
A. Non-metallic conduit shall be used below grade only AND ONLY AS permitted by the NEC, and as hereinafter specified, or as approved by the Owner's Authorized Representative. Non-metallic conduit shall, however, convert to rigid metal conduit prior to leaving below finish grade areas and concrete slab in all applications. Non-metallic conduit shall not be used above grade except for grounding systems. All stub ups, including elbows, thru slab, or from below grade, shall be rigid steel unless otherwise noted. Conduit adapters shall be used in transition. Conduit system for grounding conductors only shall be PVC in back of house or concealed locations only without metallic components, as permitted by codes and standards.
PART 2 - PRODUCTS
2.1 SCHEDULE 40 RIGID PVC:
A. Conduit shall be composed of polyvinylchloride and shall be UL rated Type 40 for use with 90 C degree rated conductors. Conduit shall conform to NEMA standards and applicable sections of
NEC.
B. Minimum size shall be 3/4"
2.2 FITTINGS:
A. All couplings, adapters, end bells, reducers, etc., shall be of same material and by the same manufacturer as conduit.
2.3 MANUFACTURER:
A. The conduit manufacturer shall have had a minimum of five years experience in the manufacture of the products. Non-metallic raceways shall be manufactured by Carlon, or Owner approved equal.
PART 3 - EXECUTION
3.1 INSTALLATION:
A. All elbows, bends, etc., shall be either factory bends or made with an approved heat bender. Direct flame shall not be applied to conduit.
B. Installation of rigid non-metallic conduit shall comply with Article 352 of the National Electrical
Code (NFPA 70) and these specifications.
C. Provide suitable expansion fittings as required on all raceways which are installed in walls subject to expansion and on raceways which penetrate expansion joints.

D. Provide a continuous, insulated, grounding conductor in every rigid, non-metallic raceway even if not shown on the drawings. The grounding conductor shall be connected to ground at each end of the raceway in accordance with Article 250 of the National Electrical Code (NFPA 70).
E. Where rigid non-metallic conduit transitions to metallic conduit, the location of the transition shall be underground.
F. All cuts shall be made with an approved saw and ends deburred.
G. No PVC conduit shall be run exposed, or above grade.
H. All joints shall be made as follows Clean the outside of the conduit to the depth of the socket, and the inside of the socket with an approved primer (colored purple) cleaner. Apply solvent cement to the interior of the socket and exterior of conduit, making sure to coat all surfaces to be joined.
Insert conduit into the socket and rotate 1/4 to 1/2 turn and allow to dry.
I. Solvent cement shall be Rectorseal Gold #844 by the Rectorseal Corporation Meeting ASTM
D2584.
J. Provide a continuous 6" wide, yellow plastic, underground utility marker tape above the full length of all underground conduits. Minimum depth 1'-0" below finished grade and 1'-0" above conduit.
K. In long sections of installed P.V.C. conduit, the Contractor shall use 90- degree elbow fittings in lieu of installing fabricated sweeps.
