Do I need a new circuit?

[Crofter]

As part of a kitchen renovation we are changing over from a standalone cooker to a built in oven and hob.

The existing wiring has a 30A fuse, 6mm2 wiring, and a single outlet for the cooker.

The new hob is a Seimens induction, rated at 7.2kw which was more than I was expecting!

I guess it would be best to use the old circuit for just the new oven, and run a new circuit for the hob?

Happy enough to go down that route, there is space on the fuse board for another 30A circuit, but if there's a safe way of avoiding the extra work and cost then clearly that would get me up and running sooner.

These big induction hobs really should be on their own circuit and to be sure I would use 10mm cable (that is what feeds our island in case we ever change the gas hob for induction)

Depends on the cable length, how it’s routed, insulation around cable ( if any)

 

if you really have fuses I would be inclined to upgrade fuseboard or atleast get an EICR Incase you redecorate and fit kitchen and wiring is substandard.

Thanks both, new circuit it is then! I thought so!

I will probably get the fuse board itself swapped out at some point, although we are in the slightly complicated position where we have two CUs, being on a two-meter tarrif, and we may change over to a single meter, single CU system.
