B. Regarding contract involvement with equipment utilizing Askarel or similar
substances that contain PCB (polychlorinatedbiphenyl) formulations:
1. The inspection request shall be filed with the Owner and the Engineer,
listing the equipment involved, its location, and other pertinent data such
as size/capacity and manufacturer. A decision concerning the course of
action to be taken with regard to this equipment will then be made by the
Owner and will become a matter of record.
27. WIRE, CABLE AND CONNECTORS
A. All building feeder and branch circuit wiring not specifically shown or
necessarily covered by code, shall be type THHN/THWN 600 volt insulation -
75 deg. C copper conductors, complying, with NEC Standards.
B. Any wire size not specifically noted on the plans shall be at least equal in
capacity to the rating of the overcurrent device serving the item to be connected
and, in addition, shall be sized in accordance with the requirements of Articles
210.19 (a) and 215.2 (b) of the N.E.C. Note that where wire sizes specifically
shown on the drawings have ampacity in excess of the protection device rating,
those sizes shall be the minimum provided.
C. Conductors shall not be drawn into a conduit segment until that segment of the
conduit system is complete, with all terminations properly bushed and with the
conduit free of moisture, foreign material, etc.
D. All connectors and lugs shall be of the solderless type and large enough to
enclose all strands of the conductors with sufficient mechanical strength to
withstand vibration and normal strains.
E. Joints or splices in branch circuit wiring and feeders must be located as per
NEC. All joints and splices shall be made electrically and mechanically sound
in accordance with best practice.
F. All parallel runs of conductors shall be cut to equal length and installed
accordingly.
G. Note that common neutrals are prohibited. An individual neutral must be
provided for each circuit.
H. Low voltage system wiring shall be sized in strict accordance with the individual
equipment and/or system manufacturer's specifications and/or recommendations
and shall be plenum rated when not run in conduit. In addition, the wire type
utilized shall be as recommended by the equipment manufacturer. Note that
where code requirements dictate, or where specified, this wiring shall be run in
conduit.
28. CIRCUIT AND CONDUCTOR IDENTIFICATION
A. All branch circuit wiring for this work shall be color coded to match existing.If
branch circuit wiring for the existing facility is not color coded, consult the
Owner regarding desired color coding for this project. Each phase shall be a
different color and the phase color shall be the same thruout the project including
branch circuiting.
