3. Conduits shall not obstruct head room, walkways or doorways.<br />
4. Conduits shall be secured to cabinets, junction boxes, pull boxes and outlet<br />
boxes by bonding type locknuts. Rigid and IMC conduit installations shall have a<br />
locknut on outside of enclosure and locknut and bushing on inside of enclosure.<br />
EMT installations may have a single locknut on inside of enclosure, wrench tight.<br />
Conduit connections shall not be made to junction box covers.<br />
5. Provide a pull wire in empty conduits, consisting of one No. 12 steel or copper<br />
wire or heavy duty nylon cord for small conduits and nylon rope for large<br />
conduits.<br />
6. Arrange conduit supports to prevent distortion of alignment by wire pulling<br />
operations. Conduit shall be fastened using straps or clamps, lay-in adjustable<br />
hangers, clevis hangers or bolted split galvanized hangers secured to structure<br />
with machine screws, expansion sleeves or lead anchors. Spring steel type<br />
supports or fasteners shall be permitted for concealed 1/2-inch EMT only. Chain,<br />
wire or perforated straps shall not be used to support or fasten conduit.<br />
7. Conduit support spacing shall be provided as required by the NEC, but in no<br />
case shall the maximum spacing of supports exceed six feet for conduits smaller<br />
than 1-inch trade size and 10 feet for conduits 1-inch trade size and larger.<br />
8. Group conduits in parallel runs where practical using conduit racks constructed of<br />
steel channel with conduit straps/damps or trapeze hangers with U-bolts or other<br />
approved fasteners.<br />
9. Fasteners shall be sized and designed for intended use. Fasteners, in solid<br />
masonry or concrete, shall be steel or malleable iron concrete inserts, 1/4-inch<br />
minimum diameter steel expansion anchors embedded not less than 1 1/8-inches<br />
or 1/4-inch minimum diameter power set fasteners with depth of penetration at<br />
least three inches. Hollow masonry anchors shall be toggle bolts, hollow wall<br />
fasteners, or concrete block anchors. Sheetmetal screws shall be used on metal<br />
studs and wood screws used on wood construction. Attachment by wood plugs<br />
or wood blocking is not permitted.<br />
3.2 CONDUIT INSTALLATION<br />
A. General Requirements: All raceways shall be installed in accordance with the NECA<br />
Standard of Installation:<br />
1. Cut conduit square using a saw or pipe cutter; de-burr cut ends.<br />
2. Bring conduit to shoulder of fittings and couplings and fasten securely.<br />
3. Use conduit hubs or sealing locknuts for fastening conduit to cast boxes and for<br />
fastening conduit to sheetmetal boxes in damp or wet locations.<br />
4. Install no more than equivalent of four 90-degree bends between boxes for<br />
power circuits and two 90-degree bends for low voltage and communications<br />
circuits.<br />
5. Avoid moisture traps where possible. Where unavoidable, provide junction box<br />
with drain fitting at conduit low point. Outdoor conduits shall be graded a<br />
minimum of six inches per one-hundred feet with no traps.<br />
6. Coordinate all conduits with other trades. Consult with Mechanical Contractor<br />
before installing conduits for electrical feeders so that conflicts between locations<br />
of conduit runs, piping, and ductwork will be adjusted prior to installation. In<br />
general, large pipe mains and air ducts shall be given priority in available space.<br />
Conduit runs shall be installed so as to maintain, wherever practical, a minimum<br />
separation of three inches from water and waste piping and six inches from<br />
steam piping.<br />
7. Provide sealing fittings, to prevent passage of water vapor, where conduits pass<br />
from warm to cold locations.<br />
8. Drilling, cutting, and patching required for conduit installation shall be as<br />
described in Section 16012.<br />
