CONDUIT RACEWAYS 260110 – 3
A. Install raceway and accessories in accordance with manufacturer's written instructions,
applicable requirements of NEC, NEMA Standards, and NECA's "Standards of Installation", and
in compliance with recognized industry practices to ensure that products fulfill requirements.
3.2 LOCATIONS:
A. Use RMC for exposed runs where conduit is subject to moisture, weather, or mechanical injury.
Use in hazardous locations in
B. Install RMC on all outdoor locations below 12 ft. and indoor locations subject to motorized and
heavy duty carts.
C. Intermediate Metal Conduit and Fittings: Use for exposed runs where conduit is subject to
moisture, weather, or mechanical injury. Use in hazardous locations in accordance with all NEC
requirements.
D. Electric Metal Tubing and Fittings: Use for above-grade feeders, branch circuits, and signal and
control circuit, unless specifically noted otherwise on drawings. Install in suspended slabs
subject to local code requirements and fire rating considerations.
E. Flexible Metal Conduit and Fittings: Use as whips for lighting fixtures, fixed equipment where
not exposed to weather of moisture, other devices where required by NEC, and as requested by
the Engineer. Maximum length not to exceed 6', unless specifically approved by the Electrical
Engineer.

fixed equipment where subject to moisture or weather, and other equipment subject to
movement or vibration. Maximum length not to exceed 6', unless specified otherwise.
3.3 METHODS:
A. Maintain a minimum of 12" clearance between steam or hot water lines or other hot surfaces.
Where such clearance is impractical, insulate conduit with approved materials.
B. Install conduits parallel with or at right angles to lines of the structure. Route conduits
symmetrically where possible.
C. Field bends and offsets shall be made without flattening, kinking, rippling or destroying the
smooth internal bore or surface of the conduit and to not less than NEC minimum radius.
Conduit that shows signs of rippling or kinking shall not be installed. Conduits installed with
wrinkles or kinks or otherwise in an unworkmanlike manner shall be replaced at no additional
cost to owner.
D. Precaution shall be exercised to prevent accumulation of water, dirt or concrete in the conduits
during the execution of the project. Conduits in which water or foreign matter has been
permitted to accumulate shall be thoroughly cleaned or the conduits runs replaced where such
accumulation cannot be removed by methods approved the engineer.
E. Any conduit which pierces airtight spaces or plenums shall be sealed to prevent air leakage with
mastic acceptable to the Architect.
