hi all,
moved home last year and ...
the old consumer box i had looked a bit past it so i thought i would change it while i was putting in an extra shower.
got a consumer unit with 10 nsb's(mcb's)
4x6amps + 1x16amp
4x32amps + 1x40amp (on the rcd side)rcd 80A 30ma
main switch 100A
shower i got mira sport 9kw
bought some 10m fte
before (old consumer) a gainsborough se 9.5kw shower had a 6mm fta from consumer with a 30amp fuse
was that right?
the old consumer unit didn't have trip itself, but whoever had put a 240v 50hz 80A load 100ma trip switch in.
so from the meter the tails went to trip switch then to old box.
i have fitted new 9kw shower (in ensuite) with 10mm cable and pull switch to 40A nsb on the rcd side
the old shower (9.5kw)(in bathroom) still has 6mm cable and ive connected to to 32A nsb on rcd side (wondered whether i should get another 40A nsb?)
have what i've done be ok?
hopefully you can understand what ive written.
thnx in advance.
