How to Wire a Smart Wi-Fi Circuit Breaker? – Automatic Remote Control Protection

In the era of 4G, and 5G, smartphones are equipped with music players, cameras, email, internet connections, and the ability to make calls to friends and relatives.

But why discuss phone calls when we’re supposed to be talking about circuit breakers and protection? Well, if smartphones can handle all these important tasks, why can’t we use them to control our circuit breakers? Electricians and sparkies are just as tech-savvy as anyone else. So, we should welcome smart home automation as well.

Obviously, this smart circuit breaker can be used to transform ordinary household wiring into a smart system with automation. For example, with scheduled operation, you can turn off and on a fan, heater, washing machine, water pump motor, etc., at specific times, and they can switch on/off automatically according to the schedule. The time setting can be done through a smartphone instead of manual operation.

Construction of Wi-Fi Circuit Breaker

Wi-Fi circuit breakers are similar to normal and ordinary circuit breakers except they have an antenna for Wi-Fi signals and a special mechanical switch mechanism for automatic on/off operation as shown in the following figure.

The following figure shows the nameplate rating data of a Smart Wi-Fi MCB.

How to Wire and Install a Smart Wi-Fi Circuit Breaker?

It is the same as an ordinary circuit breaker (which can be seen in our home distribution board) except for the antenna for remote control through Wi-Fi in the smart circuit breaker.

The upper portion is the input (Line and Neutral) while the lower is the output. In some cases, the incoming lines are connected to the lower portion in our home distribution boards. In that case, you may install the smart circuit breaker upside down in the existing distribution board for proper operation.

After installation, simply install the iOS or Android app by scanning the QR code on the product box. After installing the app, you can pair the device and set the automatic operation or scheduled time operation through the smartphone.

Note: If you are not sure how to install an MCB to the existing distribution board, contact a licensed electrician as playing with electricity is dangerous which leads to serious damage and injuries. For more details, refer to the user manual for step by step installation instruction.
