3.1 WIRING METHODS
A. Wiring Method: Install cables in raceways and cable trays except within consoles,
cabinets, desks, and counters. Conceal raceway and cables except in unfinished
spaces.
1. Comply with requirements for raceways and boxes specified in Section 260110
“Conduit Raceways."
B. Wiring within Enclosures: Bundle, lace, and train cables to terminal points with no
excess and without exceeding manufacturer's limitations on bending radii. Provide and
use lacing bars and distribution spools.
3.2 INSTALLATION OF RACEWAYS
A. Comply with requirements in Section 260110 “Conduit Raceways" for installation of
conduits and wire ways.
B. Install manufactured conduit sweeps and long-radius elbows whenever possible.
3.3 INSTALLATION OF CABLES
A. Comply with NECA 1.
B. General Requirements:
1. Terminate conductors; no cable shall contain unterminated elements. Make
terminations only at outlets and terminals.
2. Splices, Taps, and Terminations: Arrange on numbered terminal strips in
junction, pull, and outlet boxes; terminal cabinets; and equipment enclosures.
Cables may not be spliced.
3.
Secure and support cables at intervals not exceeding 30 inches (760 mm) and not more
than 6 inches (150 mm) from cabinets, boxes, fittings, outlets, racks, frames
, and

damaged during installation and replace it with new cable.
6. Cold-Weather Installation: Bring cable to room temperature before dereeling.
Heat lamps shall not be used.
C. Separation of Wires: Separate speaker-microphone, line-level, speaker-level, and
power wiring runs. Install in separate raceways or, where exposed or in same
enclosure, separate conductors at least 12 inches (300 mm) apart for speaker
microphones and adjacent parallel power and telephone wiring. Separate other
