250 V 1.5 A 20 mm type fuse was not easy to sell at home centers, but I was in trouble but the price was also cheap so I purchased 10 pieces. It is in use at all without problems.
I was saved because I was looking for this size of this size. It's so impressive as it was a monotalou because it's hard to see. It was a bit of trouble finding it even in monotalou. As we inadvertently skipped this fuse in the protection circuit as measured by the tester, we bought ten, so it is safe.
