I think the 'DIN' refers to the mounting rail.  A way is as wide as an MCB,
so an X10 module probably occupies 2 ways as it is twice as wide.

Indeed.

Should be sufficient, but _if_ I were allowed to^H^H^H^H^H^H^H^H^H^Hdoing
this I would fit 2 X10 modules side by side (4 ways) with a blanking plate
(1 way) between the 2 groups of 2 and between one of the groups and the
isolating switch.  Sort of:
DDDD-DDDD-SS where SS is the isolator, DD is an X10 DIN module occupying 2
ways and - is a blank.  Of course, someone who actually has experience of
these things (something I can only aspire to) may offer advice based on
their actual experience and not my suposition.

All sounds good to me - _I_ think you're making sense.
