It's done the same on 2 different breakers, one is a 100A one running my
whole house (only a fridge, Mac Mini and hi-fi physically on) and the other
is an 80A one at work with nothing else on it.

I'll have to see if I can measure the current draw from within the PSU since
I don't have a clamp meter.

Well, the machine works until the pop, unless the RD52 is pulling too much
but in that case I'd expect the PSU breaker to pop first. It'd be nice to
plug the PSU into a mains analyser to see if anything shows up there too,
like a sudden big draw or short to earth or something.
