Description

The MK 16A Appliances are designed to power devices up to 3kW and are intended for use with Sentry consumer units and enclosures. Here’s a step-by-step guide for installation:

1. Select Correctly Rated MCB: Ensure the correct Miniature Circuit Breaker (MCB) with a rating suitable for the appliances and based on a 230V supply is chosen. This is crucial for the safe operation of the circuit and to prevent overload.
2. Turn Off Supply: Before any installation or maintenance work, it’s essential to turn off the electrical supply to the consumer unit to prevent the risk of electric shock or injury.
3. Fit MCB onto DIN Rail: Securely fit and mount the MCB onto the DIN rail within the consumer unit, ensuring it is positioned correctly and aligned with other components.
4. Lock Clip: Once the MCB is in place, secure it onto the DIN rail by locking the clip. This ensures that the MCB remains firmly attached and stable during operation.
5. Secure Busbar and Cables: Ensure that all busbars and cables are securely connected to the MCB, following the manufacturer’s guidelines and recommendations. Proper connection prevents overheating and electrical faults.
6. Test According to Regulations: After installation, perform testing in accordance with the current IEE Wiring Regulations (BS7671) to verify the integrity and safety of the electrical circuit. This may involve continuity testing, insulation resistance testing, and polarity checking.
7. Turn On Supply: Once installation and testing are complete and deemed satisfactory, you can turn on the electrical supply to the consumer unit. Ensure that all connections are secure and that there are no signs of abnormal operation or faults.
