Just dont over fuse. The usual 1200W out amp uses 10-12A; 15A for
1500-2200W, etc at 240VAC.

## why didn't they just get off the..'get cheap program' and use a fast
breaker ??
Ideally, a 2 x pole, 15A , controlled magnetic hydraulic breaker would be the
1st choice,
one with an..."instant trip" . The instant trip types are the fastest.
They just remove the oil
from the reservoir, so it's super fast. The normal, slow, and motor start
types just use different grades
of viscosity for the oil used. I use em all the time for my various HB
projects. Any HB B+ supply
always gets a super fast magnetic hydraulic breaker..for the primary of the
plate xfmr. [they are also NOT
affected by ambient temp either].
## My Drake L4PS power supplies use 2 x 15A breakers, spaced a few inch's
apart. One per hot leg.
These are the simple push button type. [ push to re-set]. The advantage of
the 2 x pole type noted above is..
the trip bar between em ensures both sides of the 240 line open up.
## You would think for the megabuck that alpha charges for their amps, that
they would not cheap out..and use
simple fuses !
