PART 3 - EXECUTION

3.1INSTALLATION

  1. Install labels where indicated and at locations for best convenience of viewing without interference with operation and maintenance of equipment.
  2. Lettering, Colors, and Graphics: Coordinate names, abbreviations, colors, and other designations used for electrical identification with corresponding designations used in the Contract Documents or required by codes and standards. Use consistent designations throughout the Project.
  3. Sequence of Work: Where identification is to be applied to surfaces that require finish, install identification after completion of finish work.
  4. Self-Adhesive Identification Products: Clean surfaces of dust, loose material, and oily films before applying.
  5. Install Warning Labels on Enclosures containing voltages over 120 Volts: Use pressure-sensitive, self-adhesive label indicating highest voltage present. Letters to be black, preprinted on orange field. Install warning label on exterior of enclosure where plainly visible even when the enclosure door(s) are open or removed.
  6. Install Identification and Voltage Warning labels on electrical busway, including cable tab boxes, expansion sections, and bus plugs. Locate voltage warning labels every 50 feet on busway. Lettering of label to be a minimum of 3 inches tall and visible from plant floor.
  7. Install a warning label on the disconnecting device of a panel if the panel is interconnected to other equipment and remains energized from a source other than its disconnecting device. The sign shall be legible and shall read “Warning – Parts of the Control Panel are NOT de-energized by this Switch”.
  8. Install Circuit Identification Labels on Boxes: Label externally as follows:
  9. Exposed Boxes: Pressure-sensitive, self-adhesive plastic label on cover.
  10. Concealed Boxes: Plasticized card-stock tags.
  11. Labeling Legend: Permanent, waterproof listing of panel and circuit number or equivalent.
  12. Install identification as follows:
  13. Apply equipment identification labels on each major unit of equipment, including central or master unit of each system. This includes communication, signal, and alarm systems, unless units are specified with their own self-explanatory identification. Except as otherwise indicated, provide a single line of text with 1/2-inch-high lettering on 1-1/2-inch-high label; where 2 lines of text are required, use label 2 inches high. Use black lettering on white field. Apply labels for each unit of the following categories of equipment.
  14. Panelboards, electrical cabinets, and enclosures.
  15. Electrical switchgear and switchboards.
  16. Electrical substations.
  17. Motor starters.
  18. Contactors.
  19. Transformers.
  20. Apply designation labels for disconnect switches, breakers, push buttons, pilot lights, motor control centers, and similar items for power distribution and control components above, except panelboards and alarm/signal components where labeling is specified elsewhere. For panelboards, provide framed, typed circuit schedules with explicit description and identification of items controlled by each individual breaker.
