Wrap tapes at least two turns around conductor. Mark panel identification number with felt tip pen on plastic tag and attach to entering conductors with nylon wire ties. Use numbered adhesive tapes, tags or insulation color to permit identification of individual wire or cable for communication, alarm, and control conductors. Subcontractor shall submit a description of the proposed labeling method for the University's approval prior to installation of wire or cable.

J. Conductor Lubricant: Wireze, Minerallac No. 100, or equal, for installation of conductors in conduits, except that no lubricant will be permitted on conductors of isolated ground circuits.

3.2 SPLICES AND TERMINATIONS

A. Solid Conductor No. 10AWG and Smaller: Terminate on screw terminals or pressure connectors furnished as part of devices unless otherwise specified.

B. Stranded Conductor No. 10AWG and Smaller: The following installation methods shall be followed for termination of the stranded conductors:

1. All wire strands shall remain intact after the insulation is removed for the purpose of connecting the stranded wire to an approved lug or device.

2. When landing wires at a terminal strip approved for stranded wire, all strands shall be enclosed within the terminal. (No strands shall protrude from the terminal connector).

3. When using lugs for termination, all strands of the wire shall be contained in the barrel of the lug before crimping.

4. Stranded Wire shall be terminated only on devices and terminals approved for stranded wire. Number of wire shall not exceed one per termination. If the terminal is rated for more than one conductor, the number of wires shall not exceed two.

5. In the case of screw type termination points, the wire would be required to have an insulated locking fork or ring type lug approved for the wire size, crimped to the stripped conductor with an approved crimping tool for that particular lug.

6. Only ring type insulated lugs shall be used for the instrument current transformer circuits.

C. Stranded Conductor No. 8AWG and Larger: Use mechanically die-compressed connectors except where connectors of special form, such as on molded case circuit breakers, are furnished as an integral part of equipment. Compression die shall deform both connector and conductor to provide a homogeneous mass in compressed volume. Connectors and installation tools shall be products of same manufacturer. Use Thomas and Betts (T&B) and Burndy electrical connectors.

D. Splices at junction boxes shall be made with an approved, insulated, live spring type connector such as those manufactured by Scotchlock, 3M or Ideal.

E. Use Erico Products Cadweld connectors for underground splices, taps, “T” and “X” connections of bare grounding conductors, for connections to building steel members, where such connections will be inaccessible, and where such connections are specified on the construction documents.
