Power direct from the wall, or Power Conditioner?

[Vivialet]

this is exactly what I mean. The 18KW is what the Niagara 5000/7000 can deliver for some ms, this is surely a very extreme condition that you will not have in normal use. Instead of 18KW I should better say it can deliver 230V/80A instead of the 230V/10A.
As you said it is all about the transients. It would be interesting to know the max. ampere a Devialet can take...
