This paper presents a standardized, cost-effective Quality Control (QC) and testing methodology for industrial Automatic Sugar Regulator (ASR) and Motor Control Center (MCC) panels to satisfy IEC 61439 safety and thermal standards. Addressing emerging smart factory trends, the framework transitions from error-prone manual verification to automated testing via programmable logic controllers (PLCs) and automated relay test kits. This methodology ensures robust fault simulation accuracy under harsh environmental conditions—such as extreme temperatures, dust, and continuous vibrations—while validating IoT integration and renewable energy compatibility. Experimental deployment demonstrates minimized diagnostic errors, optimized testing cycle times, and reduced component waste. Ultimately, this approach enhances factory-floor reliability and extends panel lifecycles, supporting the digital evolution of heavy industrial power distribution technology.
