Default Circuit breakers/fuses in parallel

I have been looking for a 30 AMP circuit breaker to add to my rebuild
of switch panel on Herodotus.

I had often wondered if two 15 AMP ones in parallel would work and be
equivalent to a single 30 AMP one but thought "No, thats dumb - too
simple a solution" It sounded so ignorant of electricity that I was
too afraid to ask lest I be the object of ridicule.

Today the local electronics technician recommended that path to me as
the ones I wanted only went up to 25 AMPs. Showed me commercial, high
end car audio equipment with parallel circuit breakers.

May be useful information to someone else.

However wait a while to see if Larry blows me out of the water and
proves me wrong.

Larry????

It'll be OK. I won a bet 30 years ago amongst my peers, 20
electronics techs, did a demonstration, all that.

What tiny problem arises is with the timing. Two 10 Amp fuses in
parallel pop a little sooner than one 20 Amp.
