Intro: Homemade Electric Extension Board With Over Voltage Auto-Cut Function

In this Instructable I will tell you whole process of making this homemade electric extension board step by step. It is really very useful electric board. It shows Current Voltage as well as Ampere being consumed at the real time. When voltage exceeds the set limit (usually 250Volt in India) its auto-cut function works effectively. Thus our expensive appliances or gadgets remain safe even if there is an Over Voltage Danger.

Step 1: Prepare a Frame.

First of all you need to decide what type of electric extension switchboard you require. According to that you need to prepare or get prepared a wooden frame. You also may purchase it from market if the available ones meet your requirements.

Step 2: Fit the Switches, Sockets, Holder and Meters.

Now fit all the switches, 5 pin sockets, holders, voltage and/or ampere meters and led indicators etc. with screws firmly.

Step 3: Let's Start the Wiring.

Now start the wiring with discriminating properly the Line and Neutral wires. For a very impressive video presentation of its wiring process you may click here: Homemade Electric Extension Board With Over Voltage Auto-Cut Function.

Step 4: Fitting a Transformer and Auto-Cut Circuit.

For its auto-cut functionality you need to install a transformer or an SMPS of 12v 1amp. to supply the power to the circuit. So install the transformer or power supply kit wherever it is comfortable. See the video: Homemade Electric Extension Board With Over Voltage Auto-Cut Function.

Step 5: Select the Relay According to the Load.

For this auto-cut circuit you need to use a relay. Select the relay ampere according to your load. for connections in detail see this live video: Homemade Electric Extension Board With Over Voltage Auto-Cut Function.

Step 6: Make All the Wiring Connections Correctly.

To make this whole wiring process easy and comprehensible I prepared another video that is very useful and clear guiding presentation of this whole process without missing any step. You should watch it: Electric Board Wiring in a New Way.

Step 7: The Board Has Been Completed Now.

Finally the board is completed. Now let us see how it functions when there is Over-Voltage situations and then what happens when the Voltage regains its standard position. To see these functions live please click here: Homemade Electric Extension Board With Over Voltage Auto-Cut Function.
