CLEAT WIRING
• Introduction
The types of wiring to be adopted is dependent on
various factors, viz, durability, safety, appearance,
cost, consumer’s budget etc.
• Cleat wiring
This System uses insulated Cables sub protected
in porcelain cleats.
Cleat wiring is recommended only for temporary
installations. The cleats are made in pairs having
bottom and top halves. The bottom half is grooved to
receive the wire and the top half is for cable grip.
Initially the bottom and top cleats are fixed on the
wall loosely according to the layout. Then the cable is
drawn, tensioned and the cleats are tightened by the
screw. Cleats are of three types, having one, two or
three grooves, so as to receive one, two or three
wires. Two types of cleats.
Cleat wiring is one of the cheapest wiring
considering the initial cost and labor, and is most
suitable for temporary wiring.
This wiring can be quickly installed, easily inspected
and altered.
When not required, this wiring could be dismantled
without damage to the cables, cleats and accessories
BATTEN WIRING
• Batten Wiring
Tough rubber-Sheathed (T.R.S.) or PVC- Sheathed
cables are suitable to run on teak wood battens.
• Varnishing of teak wood batten
• Method of securing the battens
• Suitability of tough rubber-sheathed cable
• Suitability of PVC sheathed cable
• Painting
• Bending in wiring
• Passing through the walls
• Buried cable
• Link Clips
Link clips are used for family clipping the cables in
position.
Link clips are of two types.
• Link clip which has separate linking eye.
• Joint link clip which has combined linking eye.
Link clip are available in the following size.
25mm, 32mm, 40mm, 50mm, 63mm, 80mm, out of
which up to 40mm clips have one hole, while above
that they have two holes for fixing.
 Fig2 shows the joint link clips. These are available
in the sizes 16mm, 25mm, 32mm, 40mm, 50mm,
63mm, 80mm with a thickness of 0.32mm and have
one hole up to 40mm while above that they have two
hole for fixing.
Link clips are made of tin or brass- coated tin or
aluminum.
CASING CAPPING WIRING
Introduction
This system of wiring is suitable for low voltage
installation, in this wiring, cables like vulcanized
rubber, insulated cables or plastic insulated cables are
use and carried within the wood casing enclosures.
The wood casing wiring system shall not be use in
damp places and in ill-ventilated places, unless
suitable precautions are taken.
• Dimensions of casing.
The size of casing and capping to be used for various
sizes of 250 volts grade insulated cables in a groove
shall be in accordance with those specified in table 1.
• Bunching of circuits.
• Attachment of casing to wall and ceiling.
• Attachment of capping.
• Passing over the floors.
• Joints in casing and capping.
CONDUIT WIRING
 Introduction
• In general, a conduit is defined as a tube or channel.
Tubular conduit is the most commonly used
material in electrical installations.
• When cables are drawn through the conduit and
terminated at the outlet or switch points, the system
of wiring is called conduit wiring.
• Types of conduits.
There are four types of conduits used for wiring.
1.Rigid steel conduit
2.Rigid non-metallic conduit
3.Flexible steel conduit
4.Flexible non metallic conduit.
