I have loved to use these during the last 25-30 years, and always owersized the ampacity, so did I here to. It was labeled 25A and the max load on the circuit was 9 amp. for several hours.
Nothing else than this and 2 cm of the cables was ruined, but now I will use a contactor (rated 25A) 🙂 More noice more power to energize and hopefully more safe. 🙂
Maybe not only for non US Electrical systems, but this is in Norway at 230V 50Hz
