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

 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 Tough rubber-Sheathed (T.R.S.) or PVC- Sheathed cables are suitable to run on teak wood battens.

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.

 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. CASING CAPPING WIRING

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.

 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. 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.
