, Experiment -1
Aim of the experiment:-
To prepare an electrical switch board to control two light points, one plug point, one fan
point and fuse for main.
Objective of the experiment:-
At the end of the experiment the student will be able to
1. Make slots to prepare switch points
2. Will be able to know about the connection of point
3. Study of series and parallel connection
4. The working principle and necessity of components
Equipment required:-
Sl no. Name Specification Quantity
1 Neon tester 500v 1
2 Lamp(100w) 100w 1
3 Insulation 200mm 1
combination pair
4 Insulated screw driver 150mm 1
5 Electrical knife 75mm 1
6 Hand drill machine 1
7 Plastic switch board 12”*10” 1
8 Fuse type switch 1
9 2 pin socket 5A/230v 1
10 Fan regulator Residential 1
11 Fuse lader 5A/230v 1
12 Battery holder 5A/230v 1
, CKT Diagram
Procedure:-
1. All the material and tools are connected
2. We placed all the switches and plugs etc. on the top of the board by making with a pencil
3. The holes are made up with the help of drill machine at the making point which were
marked earlier.
4. Then fixed all the switches plug sockets and fan regulators with the screw on the board
5. The insulation part of the wire of required length are scraped and connected as per circuit
diagram
6. The connection were checked properly.
7. Connected through supply
8. Then all the components were tested.
