PART 1 - GENERAL
1.01 WORK INCLUDED
A. Requirements for identification of electrical equipment, circuit identification, system color coding and warning signs.
1.02 RELATED WORK
A. Section 26 05 00: Common Work Results for Electrical
1.03 SUBMITTALS
A. Submittal of product furnished under this section is not required.
PART 2 - PRODUCTS
2.01 IDENTIFICATION OF EQUIPMENT
A. Identify electrical equipment with permanently attached phenolic plates with 1/4" white or black engraved lettering on the face of each, attached with two sheet metal screws. Provide nameplate colors as specified in other parts of this section.
B. Include the following information on panelboard identification plates:
1. Panel Name
2. Name of panel serving it
3. Voltage and Phase
4. Branch of electrical system
2.02 CIRCUIT IDENTIFICATION
A. Identify feeder j-boxes and pull boxes with designation of panelboard/switchboard source as "FROM" and load served as "TO" with permanent labels.
B. Identify pull and junction boxes with the designation of panelboard and the circuit number of each circuit contained therein, with permanent marker. Clearly mark information on or in the box, not on the cover, so that the information is easily identifiable.
C. Identify circuits in conduits entering outlet boxes with the designation of panelboard and the circuit number of each circuit contained therein, with permanent marker.
2.03 COLOR CODE IDENTIFICATION
A. Color code phenolic plates utilized to identify electrical equipment according to which branch of the electrical system the equipment is connected to as follows:
1. Normal - Black with white letters.
2. Life Safety Branch - Yellow with black letters.
3. Critical Branch - Orange with black letters.
4. Equipment Branch - Green with white letters.
5. Generator distribution between generator and transfer switches System - Purple with white letters.
6. Fire Alarm - Red with white letters.
B. If existing equipment identification nameplates are a different color, request a ruling from the design professional to determine what color scheme to follow. For nameplates and 'C' below.
C. Fully paint outlet boxes, pullboxes, junction boxes and enclosures for emergency circuits so they are readily identified as a component of an emergency circuit. Use the following color coding scheme:
1. Life Safety Branch - Yellow
2. Critical Branch - Orange
3. Equipment Branch - Green
4. Fire Alarm System - Red
5. Generator distribution between generator and transfer switches - Purple
D. The color code as outlined below shall be used. In addition, on each panelboard, pull box, control cabinet, or other electrical enclosure that contains circuits from more than one system, provide an engraved phenolic plate and indentify the circuit conductors with the following color code:208Y/120, Phase A, black, Phase B, red, Phase C, blue, grounded conductor, white, equipment grounding conductor, green, isolated equipment grounding conductor, green/yellow stripe. 480Y/277, Phase A, brown, Phase B, orange, Phase C, yellow, grounded conductor, gray, equipment grounding conductor, green, isolated equipment grounding conductor, green/red stripe.
2.04 WARNING SIGNS
A. Provide warning signs called for by NFPA 70, by OSHA and by the list included below.
B. Use Seton Name Plate Company products, 10" x 7" size, pressure-sensitive (PSPL) for indoor use, 30 ga. baked enamel for outdoor use (30 BE) with style numbers shown below.
