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 !
