J. Support all conduit in intervals not less than 10'-0" and within 36 inches from any outlet and at each side of bends and elbows. Use galvanized, concealed conduit supports, heavy stamped, one hole malleable conduit clamps secured with nails. On exposed conduit supports, use two hole clamps with screws, or galvanized steel framed channels secured by screws may be used for conduit supports. Perforated iron for supporting conduit is not permitted.
K. Use rigid galvanized steel or I.M.C., threaded, for exposed conduit runs. Install parallel or perpendicular to walls, structural members or intersection of vertical plane and ceilings.
Avoid field made bends and offsets where possible. Do not install crushed or deformed raceways.
L. Provide metal sleeves and install where conduit passes through masonry or concrete walls.
Use No. 20 gauge galvanized steel sleeves, no more than 1/2 inch greater in diameter than the outside diameter of the conduit. Caulk conduit into sleeves with stone wool, Duseal or Oakum and weatherproof below grade. Where conduit passes through fire resistive walls, partitions, and floors, pack void spaces between conduits with U.S.G. Thermafiber or equal, as approved by the State Fire Marshal.
M. Provide a heavy nylon cord pull rope in all empty conduits for future use. Leave in place for future use in all runs and tagged with plastic tag at terminating end indicating the location of the opposite end of the conduit.
N. Use factory-manufactured ells, except where noted otherwise. Field bends are permitted for EMT conduit less than 1" diameter. Conduit radius for signal system is ten times the internal diameter of the conduit.
O. Cap or seal all conduit ends until wires are pulled.
P. Use watertight gland compression type connectors and couplings on fittings for thin wall metallic conduit. Screw type or crimp type are not permitted.
Q. Wire all rotating electrical equipment with flexible, liquid-tight conduit with appropriate slack from disconnect switch to equipment.
R. Install expansion coupling at all expansion joint locations, refer to Architectural. Drawings for locations.
S. Use approved type-bending machines for PVC conduits. Use of blow torch is prohibited.
T. For grouping, use conduit trapezes made up of suitable Unistrut or Kindorf hangers.
U. Seal or cap all conduit for a watertight installation.
V. Use approved conductor pulling machines for all underground conduits. Use of truck is prohibited.
3.7 OUTLET BOXES:
A. Attach outlet boxes on metal studs with TEC screws. Use wood screws for attachment on wood studs. Nails are not acceptable.

Technical Specifications Section 26 00 00-9
B. Cover all boxes with outlet box protector, Appleton SB-CK or approved equal. Keep plaster and dirt from entering box or panels. If plaster does get in, removed it prior to pulling in wires.
C. Close all unused openings with plugs.
3.8 INSTALLATION OF CONDUCTORS:
A. Unless otherwise indicated or specified, do not install conductors of less than No. 12 AWG size. For control conductors protected by 15 ampere or lower overcurrent protection, No. 14 AWG conductors will be installed. Where approved by Code, remote control and signal circuits utilize No. 18 or No. 16 AWG sizes. Increase No. 12 to No. 10 AWG for 120 volt home runs exceeding 75 feet.
B. Color code power wire and cable for feeders and branch circuits.
C. Install all electrical conductors, including signal and communications circuits in an approved raceway.
D. Neatly group conductors in panels, switchgear and terminal cabinets, etc., and form in a manner to fan into terminals with regular spacing. Lace formed groups of conductors with No. 12 waxed twine, or Panduit Co. Nylon Straps Numbers "SST-4-H" or "SST-2". Lace larger conductors with marlin and secure with cleats, or Panduit Co. Nylon Sta-Straps Numbers "SSC-4-H" and tie anchors ETA-1, TA-2 or TM-1-2-3.
E. Install U.L. approved covered wire from all lighting fixture lamp sockets into outlet or junction box.
3.10 WIRING COLOR CODE
A. 120/240 Volt System
Phase A - Black.
Phase A Switch Leg - Black with “S” tag.
Phase B - Red.
Phase B Switch Leg - Red with “S” tag.
Travelers - Yellow.
Neutral - White.
Equipment Ground - Green.
B. Provide identification tags on each conductor entering panel, switch, junction box and pull box to identify conductor.
3.11 UNDERGROUND PULL BOXES:
A. Set underground pull boxes at +3" above highest adjacent grade level.
B. Size per NEC.
C. Provide nameplate on all covers.

3.12 CONDUCTOR JOINTS AND TAPING:
Make joints in conductors smaller than No. 6 AWG with solderless, tapeless, wing nut type pressure cable connector. Join conductors No. 6 AWG and larger together with approved type or pressure connector and tape to provide insulation not less than that of the conductor. Make connections to switch or bus bar with one-piece copper lugs for conductors No. 8 AWG or larger.
3.13 GROUNDING:
Provide grounding for entire electrical installation as required by the serving utility and codes mentioned in these specifications. Including:
D. Conduit.
E. Neutral or identified conductor of interior wiring system.
F. Power and lighting panelboards.
G. Non-current carrying metal parts or fixed equipment.
H. Electrical panels in separate buildings.
