Distribution box jumper wire overheating
High current flow can cause the cables to heat up, especially if the vehicle's battery is deeply discharged or if the cables are too thin for the job. Solution:: Ensure you're using jumper cables with adequate gauge (thickness). According to TCVN 6610 (equivalent to IEC 60227), PVC insulated electrical wires typically operate safely at conductor temperatures up to 70°C. XLPE insulated wires can withstand higher temperatures, up to 90°C according to TCVN 5935 (IEC 60502-1). Clear definitions: “Warm” and “Overheating” “Warm”. Distribution boxes are the unsung heroes of our electrical systems, quietly managing power until something goes wrong. Homeowners often overlook common risks like loose connections, overloaded circuits, and poor ventilation. Turns out after some tries and high temperatures (even using just wires on the PCB, without tracks high-current) I stopped using a PCB, decided to get some double-pole 30A relay and wire them, controlled by a very simple PCB with a ESP32 controller.
