A few months back I bought a Cuisinart rice cooker / steamer. It gave good service until it blew its thermal fuse for no readily apparent reason. I've read a bit on this, and it seems that these fuses do this sometimes, as if the resin inside softens a bit every time the fuse gets semi-hot and eventually the widget inside the resin goes open-circuit.
I found a supplier of the right fuse in the right temperature rating, and now I'm looking for advice on how to make sure I don't blow the master RCD in the electrical box again (the fuse has live/neutral on it, the case is earthed, and I'm an idiot), nor melt the terminal block I put in to replace the fine-wire metal crimps.
The first question concerns the terminal block. I'm a little worried that I might have underspecified its temperature sensitivity, so I looked at alternatives. RapidOnline sells ceramic two-pole terminal blocks - would those be OK in these sort of temperatures?
The second question concerns sleeving to electrically isolate the bare wires of the fuse from the earthed casing. I had put the old sleeving back on the new fuse, but evidently not securely enough. What should I use to replace this? RapidOnline has a wide variety of sleeving and it's not super-obvious which is the best for this purpose.
