You need a fuse adapter to fit a small fuse into a large fuse holder. Google - cartridge fuse adapter. A good hardware store will carry them

This fuse box is fed from somewhere, right? A circuit breaker, right? Change the circuit breaker to 20A and you're done.Is there such a thing as a 250v 3"long one time fuse like the one in the link below except for 20amp? Every 20amp fuse I can find is smaller.
