I bought and wired up this 30 amp 2-pole fused disconnect box. It is advertised as "Single Phase 120/240". I have it wired up with 2 hots coming into the line at the top, then the two loads out for 240v for the rotary phase converter that came with the lathe. Unfortunately for me, it seems plug fuses are only rated to 125v and 250v ones don't exist because I can't find them anywhere. I am starting to think the design of the fuse socket itself is the limiting factor for voltage rating so it doesn't arc. I don't need the fused functionality, there is already a 30amp breaker.
Am I crazy or is it just not possible to get 240v out because 250v plug fuses don't exist. Are dummy plug fuses a "solid" connector meaning current will flow or are they an insulator to disable the circuit and fill the fuse socket? The eaton catalog still only lists the dummy fuse under 125v. Is there any proper way to fix this or do I need to start over with a different box?
