2 PART 2 - PRODUCTS 2.1 NAMEPLATES A. Nameplates shall be laminated phenolic plastic, chamfer edges, black front and back with white core, with lettering etched through the outer covering. White engraved letters on black background. B. Nameplates for emergency power (where applicable) shall be laminated phenolic plastic. Red front and back, with white core, with lettering etched through outer covering, white engraved letters on red background. C. Letter Size: 1. Use 1/4 inch high letters for identifying individual equipment and loads. 2. Use 1/2 inch high letters for identifying grouped equipment and loads. 3. Use 1 inch high letters for identifying Service Disconnecting means. D. Nameplates shall adequately describe the function of the particular equipment involved. Where nameplates are detailed on the drawings, inscription and size of letters shall be as shown and shop drawing submitted for approval. Nameplates for panelboards and switchboards shall include the panel designation, voltage and phase of the supply. For example, Panel A, 120/208V, 3-phase, 4-wire. In addition, provide phenolic label in panel to describe where the panel is fed from. For example, Fed from MDP-1:3:5. The name of the machine on the nameplates for a particular machine shall be the same as the one used on all motor starters, disconnect and P.B. station nameplates for that machine. E. The following items shall be equipped with nameplates: All motors, motor starters, motor-control centers, push button stations, control panels, time switches, disconnect switches, transformers, panelboards, circuit breakers (i.e. all 2 pole, 3 pole C.B. s), contactors or relays in separate enclosures, power receptacles where the nominal voltage between any pair of contacts is greater than 150V, wall switches controlling outlets that are not located within sight of the controlling switch, high voltage boxes and cabinets, large electrical systems junction and pull boxes (larger than 4 11/16 ), terminal cabinets, terminal boards, and equipment racks. Nameplates shall also describe the associated panel and circuit number (if applicable). F. Field install Arc Flash and Shock Warning labels on each piece of new electrical distribution equipment such as panelboards, safety switches, motor control centers, and automatic transfer switches. The labels will indicate the flash hazard boundry, the flash hazard at 18 inches, the PPE level requirements, and the approach restrictions. IDENTIFICATION FOR ELECTRICAL SYSTEMS

3 G. All Electrical System panels, transfer switches, etc. shall be labeled as per branch, i.e., Panel ABC-Life Safety Branch (similar for critical or equipment branch). H. Provide adhesion labels on inside door of each fused switch indicating NEMA fuse classification and the size fuse installed. 2.2 WIRE MARKERS A. Description: Cloth, tape, split sleeve, or tubing type wire markers. B. Locations: Each conductor at panelboard gutters, pull boxes, outlet and junction boxes, and each load connection. C. Legend: 1. Power and Lighting Circuits: Branch circuit or feeder number indicated on drawings including neutral conductor. 2. Control Circuits: Control wire number indicated on schematic and interconnection diagrams on shop drawings. IDENTIFICATION FOR ELECTRICAL SYSTEMS

4 2.3 CONDUIT/JUNCTION BOX COLOR CODE A. All conduit system junction boxes (except those subject to view in public areas) shall be color coded as listed below: Color Code for Junction Boxes Krylon Paint # System Emergency 277/480 volt Cherry Red 2101 System Emergency 120/208 volt Light Red 2110 Fire Alarm Popsicle Orange 2410 Normal Power 277/480 volt Leather Brown 2501 Normal Power 120/208 volt Glossy Black 1601 Fiber Optics Plum Purple 1929 Sound System Daisy Yellow 1813 Clock Baby Blue 1902 Intercom True Blue 1910 Computer/Data Gold 1701 TV Glossy White 1501 BAS Light Beige 2502 FIDS / BIDS Beige 2504 Security/CCTV Moss Green 2004 Telephone Light Green 2011 Grounding Fluorescent Green #3106 B. Conduits (not subject to public view) longer than 20 feet shall be painted with above color paint band 20 ft. on center. Paint band shall be 4 in length. Where conduit are parallel and on conduit racking, the paint bands shall be evenly aligned. Paint shall be neatly applied and uniformed. Paint boxes and raceways prior to installation or tape conduits and surrounding surfaces to avoid overspray. Paint overspray shall be removed. IDENTIFICATION FOR ELECTRICAL SYSTEMS

5 C. Junction boxes and conduit located in public areas (i.e. areas that can be seen by the public) shall be painted to match surface attached to. Provide written request to A/E for interpretation of those public areas which may be in question. 2.4 CONDUIT/JUNCTION BOX MARKER A. All new and existing junction boxes/cover plates for power, lighting and systems (except those installed in public areas) shall adequately describe it s associated panel and circuit reference number(s) within, (i.e. ELRW-2, 4, 6) or systems within (i.e. fire alarm, intercom, etc.). Identification shall be by means of black permanent marker. (Paint 1/2 cover plate with appropriate color as noted in 2.3 above, and mark other 1/2 with associated panel/circuit or system description as described). B. Identify conduit not installed in public areas with circuit numbers as described above. Spacing: 20 ft. on center, adjacent to color identification bands. 2.5 DEVICE COVER PLATE IDENTIFICATION A.
