Hello all,

I need to have my house DB seen to as the previous owner made a right mess of it - not sure how the Coc was ever issued.
In any case, the main breaker is an old Fuchs single pole 60A unit, which feeds into a new CBi QA17A earth leakage - which I had fitted after the old (some other brand) kept tripping.
Since the CBi QA17A is also a circuit breaker, is it OK (legal) to remove the old Fuchs SP breaker? My DB is a bit cramped, so this extra space will help.

Many thanks,
Shaun.
