Running an induction cooktop and oven on shared 32A circuit
Hi, hoping to get some advice on replacing an induction cooktop please.
TLDR: Can a 7.35kw induction cooktop and a 2.4kw oven be safely installed on a 32A circuit? And is it a job that most electricians would be comfortable carrying out? If not, would there be any reason a lower current 19.7A/4.5kW cooktop would also be problematic on the shared circuit?
Full context below, apologies for the wall of text:
My previous cooktop cracked and I’ve bought a cheap 7.35kW replacement that I thought would be a straightforward like for like job to replace.
However, an electrician who came to look at it wouldn’t take the job on because the cooktop is sharing a 32A circuit with a 2.4kW oven and therefore the maximum potential output of both devices combined exceeds the capacity of the circuit. He spoke about the potential for nuisance trips which I understand, but we’ve lived here for two and a half years and that hasn’t happened once with the existing setup (old cooktop was 7.4kW).
The options he gave were to either find a different cooktop with a lower current, completely disconnect the oven so it’s no longer usable, or add a new circuit which is not practical for reasons I won’t bore you with.
He was a very nice and trustworthy bloke and clearly cares about providing a high quality of service. I had assumed he said no due to a legal/code requirement but I’ve looked into it more and am not sure whether that’s correct or it’s more a case of what he considers best practice and is comfortable carrying out.
I don’t have an issue with returning the cooktop I bought and replacing it with a lower current one if that’s the sensible solution. Just looking for some other opinions before I go ahead with that.
Also on price - he quoted $900-1000 plus GST to replace the cooktop and install an RCD and a local isolation switch as neither of these are in place. Does that cost sound reasonable? We’re in Sydney if that’s makes any difference.
Would appreciate and suggestions and advice as I know nothing about any of this, cheers!
