Although electrical panels are the most critical link in energy distribution, errors during the manufacturing process can lead to serious safety and performance issues in the field. This article discusses the most common manufacturing-related problems and ways to prevent them.

1. Overheating and Thermal Management

One of the most fundamental problems is overheating; besides reducing performance, it also poses a fire risk. This is usually caused by inadequate ventilation, incorrect component selection, or assembly errors. The solution: conducting thermal analysis during the manufacturing process, calculating load current according to IEC 61439, and using appropriate cooling solutions (fans, natural ventilation, heat exchangers).

2. Incorrect Component Selection

A circuit breaker with the wrong current rating can disable the system's protection function. A detailed project analysis should be conducted before production, appropriate voltage and current values should be determined for each zone, and internationally certified equipment should be used.

3. Assembly and Connection Errors

Defects such as cable compression or incorrect connection of phase-neutral-ground lines can lead to breaks and short circuits later on. It is essential to route cables without creating tension, tighten them with the correct torque values, and perform functional tests after assembly. For workmanship standards...

4. Arc Faults and Lack of Insulation

Electrical arcs that occur during high current flows can cause significant damage to the switchboard and the surrounding environment. Adequate insulation materials must be used, busbar spacing must be designed according to standards, and arc fault prevention measures must be evaluated within the scope of IEC 61641.

5. Insufficient Testing and Quality Control

Skipping the testing phase due to cost concerns leads to failures in the field and loss of prestige. Every panel should undergo cabling checks, insulation resistance tests, heat and load tests, and the results should be reported.

6. Environmental Resilience Issues

For panels intended for outdoor use, a protection rating of at least IP54, preferably IP65, against dust, humidity, and temperature variations should be aimed for; UV-resistant coating and, if necessary, stainless steel materials should be selected.

7. Lack of Ergonomics

An unfriendly layout makes installation difficult and prolongs maintenance times. Device placement should be planned with accessibility, cable management, and future expansion needs in mind.

Conclusion

The common solution to these problems is engineering discipline, adherence to standards, and an uncompromising testing culture. At ElektroPanel, with our type-tested system infrastructure and routine testing protocol, we prevent all of these errors during the production phase. Contact us for your project..
