Use procedures that prevent damaging and soiling the Work during installation.

B. Color Coding: Where conductors carry unlike voltage characteristics other than those hereinbefore noted and are installed in or pass through a common enclosure, properly color code such conductors. Tag or label conductors installed in or which pass through a common enclosure with corresponding markings indicated on the Drawings or mark so that feeder or cable may be readily identified. Use nonferrous tags or pressure sensitive labels securely fastened to cables, feeders and power circuits.

C. Cables: Conceal cables in finished walls, ceilings, and floors, unless otherwise indicated.

Install exposed cables parallel and perpendicular to surfaces of exposed structural members, and follow surface contours where possible.

D. Pulling Methods: Use manufacturer-approved pulling compound or lubricant where necessary; compound used must not deteriorate conductor or insulation. Do not exceed manufacturer's recommended maximum pulling tensions and sidewall pressure values. Use pulling means, including fish tape, cable, rope, and basket-weave wire/cable grips, that will not damage cables or raceway.
