Recently we had a certified electrician in to hard-wire an induction hob. Part of the work was to replace the MCB on the board with a 32A one; previously there was a 16A MCB (since there was a gas cooker).
After his (hefty) bill, I asked the electrician whether we would receive any paperwork, but he said no since it was an existing circuit. Is that right? I guess I am asking what is the definition of an existing circuit. The moment the old MCB gets taken out, to me there is no circuit (but only disconnected cables), but does fitting the new MCB constitute a new circuit?
On a different note, as he says it was like-for-like change, he left the board as it was, with the MCB on the non-RCD side.
