There are literally dozens of varieties of fuses with different
ratings of how they blow in that configuration. I would try to find
out what Generac specs as the right fuse. For trouble shooting
purposes a 2a or 4a in any rating would work based on what you are
saying but long term I would get the one they spec. You could go to an
electrical supply or order them online. Home Depot is only going to
have the most popular sizes and ratings.



There is often a big misunderstanding about fuses.

Where I worked 2 men from the Buss fuse comapny gave a talk. At one
time they had many fuses with the statement a fuse for every
application. But the new selling point was that one fuse could replace
many kinds. Mostly all advertising hype. They even handed out a
plastic chart about 5x7 inches with all the fuses that could be replaced
by their 'newer' fuse.

As long as the fuse fits in the holder and has a high or higher voltage
rating, the fast/slow blow, and current ratings are the same it is ok to
use most any of the many types in many cases.

They could stop making any fuse rated below 600VDC and nobody would
miss them. They could make every fuse "fast quench" too. They'd just
be a lot more expensive - but the savings in stocking costs might
almost balance it out,

There are plenty of engineers who would disagree with you. Fuse
science can get pretty complicated and you certainly don't want the
same fuse protecting a HVAC compressor (long time delay, dual element)
as you would use on an inverter converter power supply (single
element, very fast acting). IBM lists over 250 fuses in the handy
dandy handbook. That is from tiny fractional amp 3/8" long solder in
fuses to bolt in blade fuses the size of a knockwurst at hundreds of
amps..
