You want to see the price of the fast acting fuses recommended to
protect the solid state relays controlling dad's kiln, I think he has
given up on the fuses as the relays are cheaper to replace.

It's the same with a stage lighting dimmer pack we had at a local
theatre. However it was much quicker to replace the very fast-acting
fuse than the triac.
