Wiring of Buildings

The following are three types of wires:

1. Sheathed wiring by surface fixing
2. Conduit installation on walls and ceilings
3. Concealed conduit wiring

Now-a-days in most of the buildings concealed PVC conduit wiring is used. The PVC conduits may be laid on the surface or concealed. In both the cases care has to be taken to see that no water enters the pipes. In the case of concealed pipe, it is safe to surround the conduit in chicken mesh reinforcement.
