RE: 3 phase supply

["Keith Doxey" <ukha@xxxxxxx>]

Hi Umar,

Have to agree with Alan on this one, unless the rating of each phase is
less
than the total load you are planning for the house you are best to stick
to
a single phase instalation. Once you get into 3 phase wiring there are
additional regulations covering the physical separation of outlets so
that
outlets on different phases arent within 2 metres of each other.

My only dealings with 3 phase in a domestic environment were several
years
ago when I rewired a freinds house for him. His wife didnt want gas in
the
house so all gas appliances were ripped out including the incoming gas
feed
and all heating in the house was electric. Because of this the house had
to
have a 3 phase supply. The way it was wired was all normal lighting and
power sockets for the whole house were on one phase, all downstairs
heating
on the second phase and the upstairs heating on the third phase. Even
then,
the location of some of the connection units for the heating had to be
changed to maintain separation.

Add X10 into the equation and you then start running into additional
problems needing phase couplers to ensure that the X10 signals are
repeated
onto the the other 2 phases.

Unless you really need to use a three phase supply you may as well
stick
with the single phase one, this would be big enough even for a large
house.

If you do use the three phase one you will need to fit a three phase
distribution board, spreading the load as evenly as possible across the
phases, you will also need to fit X10 filters to each phase and link
them
together to transfer signals between the phases, not sure of the part
number.

Unless you really need to its probably not worth the trouble.
