well,

it ocurred to me when setting up the new wiring in the kitchen that the ground
wiring is not at all alignable to the alternate current wiring.

The FI iirc depend on isolated ground wirings belonging to "their" circuit to
sense residual current.

Hence the wiring is a bit fucked up in regards to ground/FI functioning but
imho NOT in regards to safety (one can notice that with three FIs dropping
instead of just one ...)

Regarding the matter in the kitchen, i also believe in a malfunctioning device.

We have two UPS now, we could hook it up tonite and tomorrow we could
test the wiring to align the power outlets to the fuses/FIs.

Then i could get my stepfather to have a look at it (certified electrician with
the municipality), but only after everything we can do is done.

cheers,
Philip
