PART 3 EXECUTION
3.01 INSTALLATION:
A. Lettering and Graphics: coordinate names, abbreviations, colours, and
other designations used in electrical identification work with
corresponding designations specified or indicated. Install numbers,
lettering, and colours as approved in submittals and as required by code.
B. Install identification devices in accordance with manufacturer's written
instructions and requirements of Standard applicable BS or other
approved).
C. Sequence of Work: where identification is to be applied to surfaces that
require finish, install identification after completion of finish work.
D. Identify high-voltage feeder conduits (over 600 V) by words
"DANGER-HIGH VOLTAGE" in black letters 50 mm (2 inches) high,
stenciled at 3m (10-foot) intervals over continuous painted orange
background.
1- The following areas shall be identified :
(a) On entire floor area directly above conduits running beneath and
within 12 inches (300 mm) of a basement or ground floor that is in
contact with earth or is framed above unexcavated space.
(b) On all accessible surfaces of concrete envelope around conduits in
vertical shafts, exposed at ceilings or concealed above suspended
ceilings.
2- Apply identification to areas as follows:
(a) Clean surface of dust, loose material, and oily films before painting.
(b) Prime surfaces: for galvanised metal, use single- component acrylic
vehicle coating formulated for galvanised surfaces. For concrete
masonry units, use heavy-duty acrylic resin block filler. F or concrete
surfaces, use clear alkali-resistant alkyd binder-type sealer.
(c) Apply one intermediate and one finish coat of orange silicone alkyd
enamel.
(d) Apply primer and finish materials in accordance with manufacturer's
instructions.
E. Identify Junction, Pull, and Connection Boxes: code-required caution sign
for boxes shall be pressure-sensitive, self- adhesive label indicating system
voltage in black, preprinted on orange background. Install on outside of
box cover. Also label box covers with identity of contained circuits. Use
pressure- sensitive plastic labels at exposed locations and similar labels or
plasticized card stock tags at concealed boxes.

F. Underground Electrical Line Identification: during trench backfilling, for
exterior underground power, signal, and communications lines, install
continuous underground plastic line marker, located directly above line at
150 mm ( 6) to 200 mm (8 inches) below finished grade. Where multiple
lines installed in a common trench or concrete envelope, do not exceed an
overall width of 400 mm (16 inches); install a single line marker.
G. Limit use of line markers to direct-burial cables.
H. Conductor Color Coding: provide color coding for secondary service,
feeder , ..L and branch circuit conductors throughout the project secondary
electrical system as given in Division 16, Sections "Wires and Cables" and
"MV Cables".
I. Use conductors with insulation and sheathing color factory-applied the
entire -length of the conductors except in renovated existing installation
1. The following field-app1ied colour-coding methods may be used in
lieu of 10 factory-coded wire for sizes larger than 6 sq. mm.
(a) Apply coloured, pressure-sensitive plastic tape in half-lapped turns for a
distance of 6 inches from terminal points and in boxes where splices or
taps are made. Apply the last two laps of tape with no tension to prevent
possible unwinding. Use 25 mm (l-inch) wide tape in colours J as
specified. Do not obliterate cable identification markings by taping. .
Tape locations may be adjusted slightly to prevent such obliteration.
(b) In lieu of pressure-sensitive tape, coloured cable ties may be used for
colour identification. Apply three ties of specified colour to each wire at
each terminal or splice point starting 10 mm (3 inches) from the "
terminal and spaced 10 mm (3 inches) apart. Apply with a special
tool or pliers, tighten for snug fit, and cut off excess length.
J. Power Circuit Identification: securely fasten identifying metal tags or
aluminum wraparound marker bands to' cables, feeders, and power circuits
in vaults, pull boxes, junction boxes, manholes, and switchboard rooms
with 6 mm (1/4-inch) steel letter and number stamps with legend to
correspond with designations on. Drawings. If metal tags are provided,
attach them with approximately 25 kg (55-lb) test monofilament line or
one-piece self-locking nylon cable ties.
K. Tag or label conductors as follows:
1. Future Connections: conductors indicated to be for future connection
or connection under another contract with identification indicating
source and circuit numbers.
2. Multiple Circuits: where multiple branch circuits or control wiring or
communications/signal conductors are present in the same box or
enclosure (except for three-circuit, four-wire home runs), label each
conductor or cable. Provide legend indicating source, voltage, circuit
number, and phase .., for branch circuit wiring. Phase and voltage of
branch circuit wiring may be indicated by mean of coded color of
conductor insulation. For control and communications/signal wiring,
use color coding or wire/cable marking tape at .terminations and at
intermediate locations :where conductors appear in wiring boxes,
6
troughs, and control cabinets. Use consistent letter/number conductor
designations throughout on wire/cable marking tapes.
3. Match identification markings with designations used in panelboards
shop drawings, Contract Documents, and similar previously
established identification schemes for the facility's electrical
installations.
L. Apply warning, caution, and instruction signs and stencils as follows:
1. Install warning, caution, or instruction signs where required by
applicable code and where indicated, or where reasonably required to
assure safe operation and maintenance of electrical systems and of the
items to which they connect. Install engraved plastic-laminated
instruction signs with approved legend where instructions or
explanations are needed for system or equipment operation. Install
butyrate signs with metal backing for outdoor items.
2. -Emergency Operating Signs: install engraved laminate signs with
white legend on red background with minimum 10 mm (3/8-inch) high
lettering -for emergency instructions on power transfer, load shedding,
or other emergency operations.
M. Install equipment/system circuit/device identification as follows:
1. Apply equipment identification labels of engraved plastic- laminate on
each -major unit of electrical equipment in building, including central
or master unit of each electrical system. This includes
communication/signal/alarm systems, unless unit is specified with its
own self-explanatory identification. Except as otherwise indicated,
provide single line of text, with 12 mm ( 1/2- inch)-high lettering on 37

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.
3. Install labels at locations indicated and at locations for best
