The previous owner of our house, a professional electrician, installed a circuit to the garage and outbuilding using SWA 4 core 2.5mm2 cable, presumably brought back from work. I have had several doubts about the quality of workmanship in the house, so I thought to check the junction boxes with an infrared camera while charging the car. To my surprise the junction box was not particularly warm, but the cable was glowing. Even the Tesla-supplied type 2 charging cable (coiled in the second picture) was glowing a bit. I was charging at 15A, well within the ratings of the cables, and neither felt warm to the touch. Is this normal?
