this is about go down wiring .its an important practical of electrical engineering.

1. Electrical workshop
(2110005)
Topic: go downwiring
Branch: INFORMATIONTECHNOLOGY
Presented by: Acharya Mansi
(150450116001)
Guided by: Anil kayashth

2. Aim:
To study and perform the Godown
wiring.

3. Accessories:
Name No.s Rating
 Switch(1-way) 1 230v,50Hz,6A
 Switch(2-way) 3 230v,50Hz,6A
 Lamp 4 40 watt
 Fuse 1 6A
 Lamp holder 3 230v,50Hz
 MCB 1 230v,50Hz
 wires

4. Circuit diagram:

5. Procedure
 Connect the phase wire coming through the supply mains to the first terminal of
the fuse and second terminal of fuse is connected to the input of MCB.
 Output of MCB terminal is connected to the bottom terminal of switch-1.
 Second terminal of switch-1 is connected to the switch-2(2 way) of middle terminal
and top terminal of switch-2 is connected to the lamp-1.
 Connect bottom terminal of switch-2 to the switch-3(2 way)of middle terminal.
The top terminal of switch-3 is connected to the lamp-2 and bottom terminal of
switch-3 is connected to middle terminal of switch-4.
 The top terminal of switch-4 is connected to lamp-3 and the bottom terminal of
switch-4 is connected with lamp-4.
 Natural wire is connected to all the four lamps of second terminal directly through
output of MCB and circuit will be completed.

7. Advantages
 The main advantage of
godown wiring is power
saving.
 We can also save the time.
Disadvantages
 It is complicated wiring.
 Tow bulbs cannot be on at
the same time.

8. Conclusion
Thus, here now we can manage godown wiring.
