Nice bit of ASCII art there.

It would be L1 & N, L2 & N each time, not two phases.

>How is even distribution between phases solve in the UK? I guess you
don't
have even bigger fuses
out on the grid ;-). There must be three phase there I guess.  Phases
separated somewhere and feed to each house. I mean if one house uses a lot
of  power and  another feed from a different phase uses less.

As I understand it, three phase runs down the length of the street, with
the
houses taking their feed from different phases:

L1 -.-------------------.--------

L2 ---.------.-------------------

L3 ------------.------.----------


L1 L2    L2 L3    L3 L1
House    House    House
1        2        3

Phase load should tend to naturally balance out over a street / grid
branch.
That's why, should you have problems with X10, you'd best check the house
three doors down - they're probably on the same phase as you, whereas next
door is probably not.

Or all of this could be something I dreamt...
