5. Setup and Installation
Installation of this smart circuit breaker should be performed by a certified electrician to ensure compliance with all local and national electrical codes and safety standards.
5.1. Pre-Installation Checklist
- Ensure the main power supply is OFF before beginning any work.
- Confirm you have a compatible Miniature Circuit Breaker (MCB) for over-current protection.
- Gather necessary tools (screwdrivers, wire strippers, multimeter).
5.2. Wiring Instructions
- Mount the device securely on a DIN rail in your electrical panel.
- Connect the incoming live and neutral wires to the TOP terminals of the RCCB. This is critical to prevent damage.
- Connect the outgoing live and neutral wires from the bottom terminals of the RCCB to your load circuit.
- Ensure all wire connections are tight and secure.
- Connect the device to your MCB as per your electrical panel's configuration.
- Once wiring is complete, double-check all connections before restoring power.
5.3. App Integration (Tuya Smart / Smart Life)
- Download the Tuya Smart or Smart Life app from your smartphone's app store.
- Register or log in to your account.
- Ensure your Wi-Fi network is 2.4GHz (5GHz networks are typically not supported by smart devices).
- Power on the circuit breaker. The Wi-Fi indicator on the device should start blinking, indicating pairing mode. If not, refer to the device's manual reset procedure (usually holding a button for a few seconds).
- In the app, tap '+' to add a new device. Select 'Electrical' -> 'Circuit Breaker (Wi-Fi)' or similar.
- Follow the on-screen instructions to connect the device to your Wi-Fi network.
