Definition of cleat wiring: 


Cleat wiring is one of the cheapest wiring systems considering the initial cost and labor and it is most suitable for a temporary electrical wiring system. This wiring system is quickly installed, easily inspected and altered. In this type of wiring VIR or PVC insulated wire is used as a conductor.

This wiring system, All the cables are in open-air therefore fault is very easily found and replaced it very quickly and It is easy to fault detection. So nowadays cleat wiring used in most of the army Campus or festivals like marriage. 


Installation of cleat wiring:


Cleat wiring is recommended only for temporary installment. The cleat is made in pairs having a bottom and top halves. So in the bottom, half is grooved to receive the wire and the top half is for cable grip. initially, the bottom and top cleat are fixed on the wall loosely according to the layout. Then the cable is drawn, tensioned and the cleat is tightened by the screw. The cleat is of the basic three types, having one, two or three grooves, so as to receive one, two or maximum three wires. 

This wiring system is installing in a vertical or horizontal system. In this wiring system, The fault is easily replaced very easily because all the cable is open. When one circuit is the cable is passing through another circuit or cable in the cleat wiring system then insulators are used on lower cables for safety purposes. At the turning point in cleat wiring, a special type of cleat is used. The distance between the two-cleat is kept approximately 0.5 meters, 18 inches, or 45 cm and the distance between cables and wall is approximately 1.5 cm. The distance between two cable is 4 to 7 cm according to their current rating. The cleat wiring is used in most of the industry of high capacity current cables. The distance between earth and cable is approximately 2.5 to 3 cm, therefore at switches and junction boxes, the earthing points are marked. 

The cable is entered in junction box through holes and always one cable is passing through one hole. When the cable is passing through the walls or roofs then porcelain tubes or metal pipes are commonly used. The life period of this wiring is 3 months minimum and arid a maximum of 10 to 15 years.

Some precautions of cleat wiring:

  • Cleat wiring is not suitable for those place where smoke, steam, dust, and risk mechanical injury is present.
  • The cable is lying straight in cleats.
  • Do not install this wiring in as specially for stores and flammable places.
  • The cap is not tightly screwed on the base because of cable is damaged and not as loosely screw that as a result, the cable is producing sag.
  • If the cable is passing through under the water pipes, wall or roofs then cables are always passing through met conduits.
  • Switches, sockets, cut out, ceiling rose and lamp holders are always installed on round wooden blocks.
  • The distance between branch circuits for single-phase supply is not less than 2.5 cm and for sub-main 4cm minimum.
  • Always use the wooden bushing on each end of the conduit circuit.

Precautions of lead sheathed wiring

Some precautions of lead sheathed wiring include:

  • The cable should not be run over damp places.
  • The cable should be properly protected were liable to mechanical damage.
  • The end of the conduit employed must be filled to remove burrs and bushes may also use both ends.
  • The support employee must not be of such a material that may react chemically with the sheath.
  • Power wiring should be carried separately from the wiring for fans and lights etc.
  • Sharp bends should be avoided and at the corner around the bend of radius not less 10 cm should be used.
  • When the cables are being clipped these should be dressed with a piece of hardwood be to make perfectly straight.
  • Contact with the gas or water pipes, expect at one definite bond to the water mains at the point of entry, should be avoided.
  • The lead sheathed must be continuous electrically and earthed at some suitable points, preferably at the point of entry.
  • The cables must be supported by proper metal clips and saddles, etc. Which must not be more than 35 cm apart on the vertical run and 22cm on the horizontal run for cable up to 7/0.736 mm
  • According to IEEE regulations, the lead sheathed should be continuous throughout the installation either by soldering or by bonding with clamps.

Difference Between Wooden Casing Capping Wiring and Lead Sheathed Wiring

Wooden casing and capping wiring systems are suitable for low voltage domestic installation and here we are using VIR or PVC wires are used while in Lead sheathed wiring system that uses conductors that are insulated with VIR and that are covered with an outer sheath of lead aluminum alloy which contains about 95% almost lead.  Here this post gives the main key difference between wooden casing capping and leads sheathed wiring system to better understand this topic.


What is the wooden casing capping wiring system?


Wooden casing capping wiring system was famous in the wiring system in the past. This cable is used in kind of wiring were either VIR or PVC or any other approved insulated cables. The cable was carried through the wooden casing enclosures. The casing is made up of a strip of wood with parallel grooves cut lengthwise so as to accommodate some VIR cables. The capping used to cover the wires and cables installed and fitted in the casing.

What is lead sheathed wiring system?


The lead sheath is earthed at each and every junction to provide a path to ground for the leakage current. They are fixed means that of metal clips on wooden battens. The wiring system is very expensive. It is suitable for low voltage applications.


A key difference between wooden casing capping and lead sheathed wiring system:

  • The cost of a medium in a wooden casing capping wiring system while in lead sheathed wiring system cost is high.
  • Both of the wiring the voltage is low around 250 V.
  • We are using lead sheathed wiring life is long, but in wooden casing capping, the cost is fairly long.
  • Mechanical protection is good in both the wiring system.
  • Appearance is fair in both the wiring system.
  • General reliability is good in wooden casing capping wiring while in lead sheathed wiring reliability is fairly good.
  • Dampness protection is poor in wooden casing capping but in lead sheathed wiring dampness protection is good.
  • Highley skill labor is required for wooden casing capping.
  • While we are using the material must be used PVC, VIR, screws, board, block, wooden gutters but in lead sheathed wiring lead sheathed cable, wooden, clipboard, round board, wooden gutters, etc.
  • Wooden casing capping wiring is mostly used in a commercial office building, residential but nowadays being replaced by TRS wiring on account of additional advantages while in lead sheathed wiring is mostly used in service main. because of the high cost and heavy short circuit in case of leakage.

Precautions of Batten wiring

Some precautions of batten wiring include: 

  • If the cable is passing underwater pipes or walls then metal pipes are used.
  • Use the correct size of clips, if large clips are used then the beauty of wiring is not maintained.
  • Always installed the batten to the hight of 5 above the ground.
  • Use bridge joint when crossing of cables is required.
  • Always varnish the batten before installation.

Precautions of conduit wiring

Some precautions of conduit wiring include:

  • The metal pipes or conduits are terminated in a metal-clad board with a smooth bor brass bush or ring brass bush.
  • Always draw the exact number of the wires into the conduit.
  • Always select the correct size of the conduit.
  • When curve the conduit then elbows or bends are used.
  • Select the exact routes before the installation of the conduit. 
  • When the exact large length of the conduit run then must provide the inspection point on this conduit.
  • If two or more than two conduits are run in parallel then multiple saddles must be used for wiring.
  • Before drawing the cable in conduit, make sure that there is no moisture is present in the interior of the conduit.
  • Always use the steel wire to draw the cable through steel or PVC conduit.
  • In the case of a steel conduit, the sharp edge of the conduit must be smooth.
  • Use the correct size of the saddle according to the diameter of the conduit.
