This is all well and good in theory but what happens when new
occupants move into a house, with various load appliances ?

Unless they alter the kitchen layout, similar appliances will end up in
similar positions - no problem. If the kitchen is radically altered
then wiring work is likely and the Part P registered electrician will of
course re-check the design :-)

Are the regs soon going to tell us where we can place our appliances?
Have there been cases of houses being damaged by misplaced appliances
on properly installed ring mains ?
This issue seems on the surface, to be getting out of hand.

There are certainly cases where cables have been damaged due to failure
to consider the requirement to avoid the likelihood of long-term small
overloads [433-01-01]. Hence the clarification added to 433-02-04 in
respect of ring circuits in Amendment 1 to BS 7671:2001.

Nothing's getting out of hand, but more emphasis is now placed on
ensuring that the regs are actually complied with, and on making
installers realise that there is a design process (however trivial)
involved in wiring work.
