Andy Burns coughed up some electrons that declared:

I'd be tempted to split the load across multiple 16A outlets, to reduce
the total inrush current per circuit, also switch to type-C MCBs.

Agree. At Imperial College, we had this problem - had to go to type-D
breakers in some cases, but the design considerations for putting type D in
are onerous (eg you need a *very* low L-E impedance back to the supply:
fortunately the 11kV transformers were round the back of the building and
the College has a resident Electrical Engineer to worry about these
things).


Alternatively consider intelligent power distribution strips which can
sequence the servers back on after any power cut, and have the advantage
you can remotely power them off/on if required.

APC masterswitches were good at this, and allowed for remote power switching
via RS232 and ethernet. Think that range has been superceded, but it's
likely APC still make something similar.
