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"

I wonder about the original premise, as I have a 50 amp breaker. It's
not in the panel, in fact it protects the panel, but they exist. As I
recall, it mounts through a 1/4 or 3/8" hole, a simple push-button.

The shop - Jaycar, a nation wide store in Australia similar to what
Radioshacks used to be like did not had the push buttom type you write
of in 50 AMPs but not in 30 in their rather extensive catalogue.

Peter,

I assume that you are looking for an "If all else fails this one
blows" sort of devise like the main entrance fuses on a house.

Try any commercial electric shop. You probably will have to be
satisfied with an "AC" breaker but, hopefully, you are not using it as
a switch. As a safety device it will work just fine. A friend of mine
did empirical tests on "AC" breakers using 12 VDC and the breakers
trip at the rated amperage. If you don't like that idea use a fuse -
the kind that have a copper tongue at each end. Drill a hole and bolt
them into the system.

I'm still in the yard. Top sides done and now trying to finish the
bottom in between rain squalls. The bottom is faired and mostly sanded
- hopefully we'll finish that today. then a seal coat, which we will
need good weather for and then a tie coat and the anti-fouling and
back in the water.

I've been doing an anti-rain dance on the fore deck every morning but
it isn't working very well - clear at 06:00 and by 09:00 black clouds
building up in the west.
