Non-fusible disconnect wires can get burned due to several factors, including loose connections, overheating, and corrosion. These issues can lead to increased resistance and heat, which may cause the wires to overheat and potentially catch fire! To catch these issues, regular maintenance and inspections are essential. Inspect the disconnect box for signs of overheating, such as distortion or cracks in the plastic, and ensure that all connections are tight and secure. Additionally, consider using a safety mechanism like a position indicator to enhance operational safety. If any issues are found, they should be addressed promptly to prevent further damage and ensure the safety of the electrical system.
