Onderwerp: Re: OT: american vs european 220
H,
But I think European 220 doesn't work this way. Is one 220 leg
delivered to the house? And the electronics work off that 220 leg?
Or are two 110 lines delivered and every outlet gets the sum of those
two 110 lines?
Here in the Netherlands, most domestic houses do have a single leg 240V
power.
For an additional 'connection fee' you can get 3 phase power delivered.
I have 3 phase power at home, guess why....

If it's not two separate legs, I'm thinking that it will be impossible
to wire an american 220 appliance to work with european 220. Is this
right?

In most western Europe countries the power systems are 3-fase 230V with a
180 degrees phase-shift.
Neutral is earthed at the distribution (10kV ->230V) transformer . So only
the phase(brown) wire has a voltage potential to earth.
The voltage between earth, neutral and the other legs is always 230V AC and
between the 3 phase legs 400V AC.
Most new houses in NL are wired for a 3 phase-system but at the power inlet
just one leg is fused so the owner sees a 1 phase-system, but it easy (for
the power company) to upgrade to a 3 phase-system ( 2 fuses and a new
powermeter).
And yes I do have a 3-phase system with also a separate earth system for
measurement systems.
