Choosing the right types of wiring is important as wiring connects various accessories for the distribution of electricity from supplier meter board to many domestic appliances.
There are various types of wiring:
- Tee system or Joint box system
- Loop-in system
- Cleat Wiring
- Batten Wiring
- Casing and Capping Wiring
- Lead Sheathed Wiring
- Conduit Wiring
Connection of appliances is done with this wiring. It does not consume too much of cable size so it is ideal for temporary installations and it is cheap.
This system is used in such a way that the lamps and other appliances are parallely connected so that each appliances are controlled individually.They are easily accessible for finding faults.
This wiring consists of ordinary VIR or PVC insulated wires and are braided and compounded on walls and ceilings by means porcelain cleats, wood or plastic. It is kind of temporary system and is not suitable for domestic usage. For example, used in under construction building.
This kind of wiring uses single core, double core and three core TRS cables. These cables can be steam proof, chemical proof and waterproof. It is cheap compared to any other electrical wiring systems in an electric circuit.
Casing and Capping Wiring
In this wiring, the VIR cables are enclosed under wooden casings. It is obsolete now these days. Repairing is easy when the phase and neutral wire are separately installed in slots.
Lead Sheathed Wiring
This contains electrical conductors which have an outer sheath made up of aluminium alloy containing 95% lead. These sheath protects the cables from atmospheric corrosion, moisture and mechanical damage.
This kind of wiring is further classified into surface conduit wiring and concealed conduit wiring
Surface Conduit Wiring
These types of wiring are installed on the roof or walls. Here, holes are made at equal distance and conduit is installed with the help of plugs
Concealed Conduit Wiring
These are hidden inside the walls by plastering it with the help of plastic or metallic piping and
Depending upon the type of piping, these are again classified into:
These are made of steel which are costly but very strong. Metallic conduit is again classified into:
Class A Conduit
Thin layer of sheet made of steel or also called as low gauge conduit
Class B Conduit
Thick layer of sheet made of steel or also called as high gauge conduit
These uses flexible and easy to bend wires such as solid PVC conduit.
