What does 100as/100af refer too?

We have an engineer's note on a project that says "Provide Fused Disconnect Switch 100AS 100AF 3P disconnect switch." I can't find those references in any of the supplier catalogs. What do they mean?

Submit an RFI and ask.

100 ampere switch and 100 ampere fuse

He is mixing apples and oranges...these parameters usually refer to
"Trip setting/Frame size" for breakers, but he has asked for a fused disconnect not a breaker;however, you should submit a RFI.

I agree with Ron, no RFI needed this is common nomenclature.

Yep, what Ron said.

100 ampere switch and 100 ampere fuse

Well that's too easy. Thanks. BTW, our panel supplier wasn't sue what it meant either.

The reason this can be important is because sometimes the engineer wants a larger fused switch then needed for the load.

For instance they might specify a 200 amp switch with a 100 amp fuse.
