Enclosure: It shall have lifting eyes and a front door provided with a key locking handle.
All switches, fuses, terminal blocks, etc., shall have permanent nameplates or labels for
identification. All wiring shall be identified with wiring markers with alphanumeric
characters. The identification of each wire shall be the same as that shown on the
electrical schematic. Each wire shall be so identified at each end. Each end of every
wire shall be provided with a heat shrinkable or equivalent sleeve-type wire markerlabeled
in accordance with the electrical schematic. Use of adhesive and clip-on type
markers is prohibited.
Panel wiring shall be as follows:
1. Each conductor terminated under a screw head shall have a crimp on spade
terminal applied to its end prior to its termination.
2. Each conductor has its own number and no number is used more than once.
3. The number of each wire is placed at both ends of the wire next to its end
according to wire tagging instructions as specified in 26 05 19, “Low Voltage
Electrical Power Conductors and Cables”.
4. The wire numbers, as actually installed, match the numbers on the shop
drawings, O&M manuals, wiring diagrams and interconnection diagrams for this
instrument panel.
5. Conductors run open shall be bundled and bound at regular intervals not to
exceed 6" with nylon ties, or approved equal. Wires within a bundle are to be
run parallel to one another and not twisted. Bundles shall have a uniform
appearance, circular cross section, and shall be securely fastened to the panel
framework. Conductors carrying different voltages that are from the same source
may occupy the same wireway provided all are insulated for the maximum
voltage of any conductor in the wireway. Wiring carrying voltages that originate
at different source shall not run in the same wireway.
6. A separate 120VAC Terminal Block and circuit breaker shall be provided for the
cabinet.
Provide a print pocket pouch with the control schematic drawings on the inside of the
Panel door. The control schematic drawings shall be the final version of the drawings
and shall include any field revisions made during start-up.
All relays and pushbuttons shall be NEMA rated, heavy duty type. IEC or dual
IEC/NEMA rated equipment shall not be acceptable.
Terminal strips shall be 600V, NEMA rated manufactured by Allen-Bradley, Phoenix
