I was shopping fuses at Great Plains because I needed to make up a $5 minimum order so I could get my trimmer for the sound board on Mystic.

Not being able to find the fuses as stated in the parts book, I sent them an email asking if maybe they had them.

I was looking for
10A 32 v
.75A 250 v
4A 32v
20A 32v
5A 32 v.

Their response was that I could use 250v rated fuses for all (except the 20 amp, which only comes in 32v rating). Is that kosher?

I think that Mouser has what I need, but I'd rather get them from Great Plains so I can have a $5 min order.

If the originally intended fuse will blow over 32v, why is it safe to use a fuse that won't blow until the load exceeds 250V?

Thanks. Very understandable explanation
