Hi. What current are the thermal ones that did not jump? However, if you want to minimize the power outages in the place you can put together a small board that you will plug into any outlet, which contains a differential and a thermal of 2 x 10 amps. In this way you will limit possible problems a bit. Another option is to use a serial connection for example with a disused iron or a large reflector. Before connecting any device under repair as a test you can connect it here first. If it is short nothing will happen. The reflector will turn on in full brightness or the plate will turn on but nothing will burn or any fuse or thermal will blow. Regards
