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.
I came across that in a 110 volt 3 phase to DC transformer many years ago.
The fast acting fuses were failing frequently costing about £3 to replace.
Just checked the emails and these were £13 each, with minimum quantity
of 10.
