C. Conduit shall be installed as a complete system, continuous from outlet to outlet, cabinet, box for fitting and be so mechanically and electrically connected that adequate electrical continuity from one conduit to another is secured.

D. Conduit shall not run through any structural member of the building, except as specifically directed by the Contracting Officer. This shall not prohibit conduit run through open web trusses or through factory made openings in structural members. Conduit run through ribbed slabs shall run at 45 degree angles to joists or parallel and in the joists.

E. On exposed runs of conduit where junctions, bends, or offsets are required, provide condulets whether such condulets are indicated on the drawings or not. Bends will not be permitted around corners or beams, or equipment.

Condulet covers shall be accessible. Condulet fittings shall not be used on conduit larger than 1-1/4" trade size. Use junction boxes on larger conduit.

F. Separate conduit shall be used for each home run indicated on the drawings.

Do not combine conduit runs. Run exactly as shown on the plan.

Support or fasten all conduit runs at intervals not to exceed 5'-0" on center. Single runs of conduit may be supported with 12 gauge galvanized tie wire. For multiple runs, use conduit trapezes made of suitable Unistrut or Kindorf channel with threaded rod (not less than 1/4" outside diameter) and suitable conduit straps. For multiple exposed conduit runs, use unistrut or Kindorf channel suitable conduit straps. Channels embedded in concrete shall not be deeper that 7/8". Nails, perforated strap and plumber's tape are not acceptable means of support.

H. Conduit shall not run closer than 6" to any hot water pipe, steam pipe, heater flue or vent.

I. Projections through roof shall be made watertight by proper flashing and/or pitch pockets satisfactory to the Roofing Contractor and/or Contracting Officer. Verify the method prior to rough-in and comply as required.

Contractor shall supply all required roof jacks.

J. The use of pliers for tightening of conduit connections or making up runs of conduit is prohibited. All conduit joints and connections shall be wrench tight.

Plug each end with conduit pennies and bushings and leave plugged until ready to pull wire. Wood or fiber plugs or concrete nails are not acceptable.

L. The ends of all conduit shall be cut square and carefully reamed out to full size with a tapered burring reamer and shouldered in the fitting.

M. No running threads will be permitted, special union fittings shall be used in lieu therof. The open ends of all conduit shall be kept closed with approved conduit seals during the construction of the building. Rigid conduit couplings shall be of the threaded type.

N. Except as otherwise indicated on the drawings, bends in conduits 1" and larger shall be made with standard conduit ells. Wire or cable bends in junction boxes or pull boxes shall be made on long radius of not less than five times the diameter of the cable. Nesting of conduits shall be made when more than one conduit is used in parallel without the use of standard ells.

C. The Contractor shall verify the actual nameplate ampere rating of all equipment and shall select fuses based on the following criteria:

D. For motors: Fuses shall be rated not over 125% of the motor full load running current. If possible, select fuses rated between 105% and 115% of the motor full load running current.

E. For packaged A/C units: The fuse size must not exceed the "Maximum Fuse Size" listed on the unit nameplate.

3.7 GROUNDING

Use grounding bushings with EMT and double lock nuts with rigid steel conduit of IMC for all circuits over 250V to ground (277/480V systems).

Provide grounding bushings on all conduits connected to concentric knockouts for all system voltages.

D. The conduit system (Rigid Metallic Conduit, IMC and EMT) shall be permitted to serve as the equipment grounding conductor for all branch circuits rated 50A or less, except where otherwise indicated.

E. For branch circuits rated over 50A and for all feeders, provide a green uninsulated equipment grounding conductor sized in accordance with Table 250-95 of the National Electrical Code, but in no case smaller than No 6 AWG. Such conductor shall be installed in the raceway along with the circuit conductors whether or not shown on the drawings.

F. For all circuits and feeders run with non-metallic conduit, provide a green insulated equipment grounding conductor.
