RE: big Consumer units

["Hawes,Timothy Edward \(GEG\)" <haweste@xxxxxxxxxxxxxxx>]

ISWYM now. I was confusing the "15A Breaker" with the DP
isolation
switch on your existing CU. I was wondering why someone would only have
a 15A supply for all their household circuits, D'oh.

16A seems to be the next standard size of MCB, but now that I understand
your question properly, I don't think I can answer it :-(

Cheers,

Tim.
