1. Ensure that all the exact wires (+ve, -ve, earthen) are connected for the switches.
2. Check the switches by on/off with ligts and fan.
3. Ensure that the fuse is well (advanced) for the Switch board.
4. Check the load by inserting multiple plug points.
5. Ensure that the Electricity provide should be in between 220 to 240 volts in Switch on.
6. Ensure that the Current phase should trip once the high voltage is passed to the switch board.

1) check whether all the switches in the board are  in proper condition  or not.

2) check whether all the switches have proper wire connection. 

3) If there is a two way switch check whether it works properly .

4)check whether the voltage is in specified range.

5) check whether the corresponding switches work.example (if U turn on the light switch ;the light should glow) 

6)check whether U get a shock when U switch ON in wet hands ( negative test case )

7) check whether the supplies doesn't work then tripped because of high voltage.
