Исправляем ошибки в квартирном щитке

Introduction

This tutorial addresses common mistakes found in electrical panels, based on insights from an expert electrician, Georgiy Krivenko. By understanding and fixing these errors, you can enhance the safety and efficiency of your home’s electrical system.

Step 1: Correcting the Connection of Conductors

• Avoid connecting two or more conductors to a single terminal on the PE busbar.
• Ensure each conductor has its own dedicated terminal to maintain a secure and reliable connection.

Step 2: Proper Arrangement of Low-Voltage Conductors

• Ensure low-voltage wires are arranged neatly and separated from high-voltage wires.
• Use cable ties or clips to keep them organized and avoid interference or accidental short circuits.

Step 3: Selecting the Right Circuit Breakers

• Choose automatic circuit breakers based on the specific load requirements of the appliances they will protect.
• Check the amperage ratings and ensure they match the expected load to prevent overloads.

Step 4: Correcting Jumper Connections

• Ensure that jumpers between circuit breakers are correctly configured.
• Use phase buses to ensure proper phase distribution and avoid potential overloads.

Step 5: Proper Use of Residual Current Devices (RCD)

• Make sure RCDs are used appropriately within the circuit.
• Regularly test RCDs to ensure they are functioning correctly and can trip in case of a fault.

Additional Considerations: Understanding Selectivity of RCDs

• Familiarize yourself with the concept of selectivity in RCDs to ensure that only the affected circuit trips during a fault.
• Use RCDs with different ratings for various circuits to enhance the overall safety and functionality of your electrical system.

Conclusion

By addressing these common mistakes in your electrical panel, you can significantly improve the safety and reliability of your electrical system. For further assistance, consider consulting with a professional electrician. Regular maintenance and checks are advisable to ensure continued compliance with electrical safety standards.
