2. Branch Circuits After First Junction Point: 1/2-inch.

B. Dry Locations:

1. Exposed: EMT.

2. Concealed in Walls or Ceilings: EMT.

3.5 RACEWAY INSTALLATION

A. Install raceways in accordance with NECA “Standard of Installation” and manufacturer’s recommendations.

B. Route exposed raceways parallel and perpendicular to walls.

C. Conceal raceways and cables, unless otherwise indicated, within finished walls, ceilings, and floors.

D. Run raceway plumb, level, and in a direct line, with long sweeping bends and offsets.

Make changes in direction of raceway with symmetrical bends or metal fittings.

E. Keep legs of raceway bends in the same plane and keep straight legs of offsets parallel.

F. Maintain 12-inch clearance between conduit and surfaces with temperatures exceeding 1040F.

G. Use conduit hubs or sealing locknuts to fasten conduit to sheet metal boxes and cast boxes in damp and wet locations.

H. Install no more than equivalent of four 90-degree bends between boxes. Use conduit bodies to make sharp changes in direction.

I. Seal wall and roof penetrations weathertight.

J. Grout around conduit tie-ins entering building walls. Where conduit enters buildings, seal openings with duct seal to prevent circulation of air or moisture.

3.6 WIRE AND CABLE METHODS

A. Conductor Size:

1. Meet requirements of NFPA 70 or the sizes shown on the drawings if larger.

Use no wire smaller than No. 12 AWG for power and lighting circuits, and no smaller than No. 16 AWG for control wiring.

2. Use No. 10 AWG conductor for 20 ampere, 120 volt branch circuit home runs longer than 75 feet.

B. Wire and Cable Application: Use wiring and cabling methods specified below to the extent permitted by applicable codes.

1. Service Entrance: Type SE, Service entrance cable.

2. Concealed Interior Feeders and Branch Circuits: Building wire in raceways.

3. Exposed Interior Locations: Building wire in raceways.

4. Exposed, Above Accessible Ceilings, or in Attic: Building wire in raceways.

5. Wet or Damp Interior Locations: Building wire in raceways.

6. Exterior Locations: Building wire in raceways.

7. Remote-Control Signaling and Power-Limited Circuits, Classes 1, 2, and 3:

a. Concealed: Insulated conductors in raceways.

b. Exposed, Above Accessible Ceilings or in Attic: Signal wire supported every 4 feet by bridal ring Insulated conductors in raceways.

3.7 WIRE AND CABLE INSTALLATION

A. Taps and Splices:

1. Permitted only in junction or outlet boxes.

2. Make splices and taps that are compatible with conductor material and that possess equivalent or better mechanical strength and insulation ratings than unspliced conductors.

B. Place an equal number of conductors for each phase of a circuit in same raceway or cable. Pull all conductors into a raceway at the same time.

3.8 IDENTIFICATION MATERIALS AND DEVICES

A. Install at locations for most convenient viewing without interference with operation and maintenance of equipment.

FOR ELECTRICAL

B. Coordinate names, abbreviations, colors, and other designations used for electrical identification with corresponding designations indicated in the Contract Documents or required by codes and standards. Use consistent designations throughout Project.

C. Self-Adhesive Identification Products: Clean surfaces before applying.

D. Nameplates: Identify panels, motor starters, control points, and disconnect switches.

1. Remotely Mounted Controls: Identify the equipment controlled.

2. Panels: Identify panel number, feeder number, and voltage of panel bus.

3. Safety Switches, Relays, and Motor Starters: Identify equipment controlled and circuits from which they are fed.

E. Wire Markers: Install at each end of each wire interconnecting between such items as control panels, sensors, and control devices. Wire markers shall correspond to control wire numbers on schematic diagrams.

F. Tag and label circuits designated to be extended in the future.

G. Install warning labels on panels, disconnects, and other devices as required by NFPA 70.

3.9 INSPECTION

A. Demonstrate that electrical work operates satisfactorily and in accordance with the requirements of the drawings and specifications. Before final inspection, remove the front covers on all panelboards and wire gutters. Replace covers after the final inspection is completed.
