Popped round my old dear's yesterday. She quite fancies replacing her ceramic hob with an induction one, so I thought I'd take the oven and existing hob out to see what state the wiring is in (property built 1930s although I expect probably had a refurb at some point in the 70s or 80s, but nothing since).

Anyway, pics attached of what greeted me. The oven & hob are both wired to a single cooker outlet plate, with a cable going back to a 32a breaker on the consumer unit.

Issue I have is that the hob is 2.8kW & oven is 6.6kW (9.4kW). Based on a 32a breaker x 230v = 7.4kW. So that little combo there is 28% over the breaker rating.

However, I think the reason why the CU doesn't kick in is because the old dear hardly ever uses both hob & oven on full whack.

Anyway, my question is, setting aside theory and regs for a sec, in the real world what I found, how much of a potential issue is this?

I'm also itching to change the cooker outlet plate to a nice modern one (I have lying about as a spare).
