And the mains plug fuse doesn't blow? This does not sound like an 
overcurrent fault to me. Is the 100A breaker an RCD type of thing? 
(actually, it sounds like a 100A-rated RCD used as a main switch in the 
consumer unit to me, those are _not_ 100A breakser and will not trip on 
over-current, just on earth leakage).

Actually, I'd expect the PSU to go into overcurrent shutdown mode or 
something. In gneral, the input circuit breaker only trips if there's a 
failure i nthePSU iteslf. Any problem with the load will shut the supply 
down with no other effects
