SECTION 260553 - ELECTRICAL IDENTIFICATION: continued
fastening except where adhesive mounting is necessary because of surface it is mounted
to.
a. Thickness: 1/16 inch, for units up to 20 square inches or 8-inch length; 1/8 inch for
larger units.
b. Fasteners: Self-tapping stainless steel screws. Utilize contact-type permanent
adhesive where screws cannot or should not penetrate surface mounted to.
2. Lettering and Graphics:
a. Coordinate names, abbreviations, and other designations used in electric
identification work with corresponding designations shown, specified, or scheduled.
Provide numbers, lettering, and wording as indicated, or if not otherwise indicated,
as recommended by manufacturer or as required for proper identification and
operation/maintenance of electrical systems and equipment. Comply with ANSI
A13.1 pertaining to minimum sizes for letters and numbers. Comply with OSHA
requirements. Comply with color requirements of ANSI Z53.1.
K. Panelboard branch circuit color coding shall be posted at each panelboard per NEC 200.6(D).
L. Self-adhesive white strips with printed circuit numbers for all light switch wall plates and
120Vac, 60-hertz receptacle wall plates.
PART 3 - EXECUTION
3.01 APPLICATION AND INSTALLATION:
A. General Installation Requirements:
1. Install electrical identification products as indicated, in accordance with manufacturer's
written instructions and requirements of NEC.
2. Coordination: Where identification is to be applied to surfaces which require finish
painting, install identification after completion of painting.
3. Regulations: Comply with governing regulations and requests of governing authorities
for identification of electrical work.
B. Conduit and Cable Tray Identification Markers:
1. General: Where electrical conduit is exposed, apply identification markers on electrical
conduit at 20-foot intervals (visible from the floor) and within 3 feet of all panelboards,
switchboards, switchgear, automatic transfer switches, substations, switches, devices, and
circuit breakers (readily visible when standing in front of equipment). Identification on
cable tray shall be on outside of both sidewalls at 20-foot intervals.
C. Underground Cable, Conduit, and Duct Bank Identification Marker:
1. General: During back-filling/top-soiling of each exterior underground direct buried
electrical, signal or communication cable, conduit and duct bank, install continuous
underground-type plastic line marker, located directly over the direct buried cable,
conduit or duct bank at 12 inches below finished grade. Where multiple small direct
buried cables are buried in a common trench and do not exceed an overall width of
16 inches, install a single line marker.
2. Install line marker for every cable below grade, regardless of whether direct-buried,
protected in conduit, or conduit in duct bank.
D. Wire/Cable Identification Bands:
1. General: Apply cable/conductor identification bands, including circuit number, on each
wire/cable in each box/enclosure/cabinet where wires of more than one circuit or
communication/signal system are present. Match identification with marking system
used in panelboards, shop drawings, contract documents, and similar previously
established identification for project's electrical work.
