Residential House Wiring I ANNA University I EP lab I Rajasekar Madhavan

Residential House Wiring Theory:
Conductors, switches and other accessories should be of proper capable of carrying the maximum current which will flow through them. Conductors should be of copper or aluminum. In power circuit, wiring should be designed for the load which it is supposed to carry current. Power sub circuits should be kept separate from lighting and fan subcircuits. Wiring should be done on the distribution system with main and branch distribution boards at convention centers. Wiring should be neat, with good appearance. Wires should pass through a pipe or box, and should not twist or cross. The conductor is carried in a rigid steel conduit conforming to standards or in a porcelain tube.
A switch is used to make or break the electric circuit. It must make the contact finely. Under some abnormal conditions, it must retain its rigidity and keep its alignment between switch contacts. The fuse arrangement is made to break the circuit in the fault or overloaded conditions.
The energy meter is used to measure the units (KWh) consumed by the load.

PROCEDURE:
1. Study the given wiring diagram
2. Make the location points for energy meter, main witch box, switchboard, and lamp.
3. Draw the lines for wiring on the wooden board.
4. Place the wires along with the line and fix.
5. Fix the bulb holder, Switches, Socket in marked positions on the wooden board.
6. Connect the energy meter and main switch box in marked positions on the wooden board.
7. Give a supply to the wires circuit.
8. Test the working of light and socket.
