Answer :

List the types of Internal wiring in residential installations –

1) Cleat wiring

2) Batten wiring

3) Wooden casing capping wiring

4) PVC conduit wiring

5) PVC casing capping wiring

6) Concealed wiring

Explanation : 1) Casing Capping type wiring system: The cost of wiring is slightly more. The PVC or VIR wires are carried through PVC casing capping. This wiring is very simple so it is widely used. More number of wires can be carried through the different size of PVC casing capping. Wires are not exposed to the sky, so there are less chances of mechanical injury. Future expansion is possible and repairing and maintenance is easily possible.
