The OP is in Germany, designing a machine for the USA.

He has not made any comments to any of the responses here, as of yet.

WE all have to remember that the NEC is not a design tool, but the minimum (or maximum, in some cases).

To the 'microwave' comment from Reno...is it a dedicated circuit for the micro, on #12 & a 20 amp OCP, with a single 20 amp, 120 volt receptacle??
