I want to replace our old electric stove that currently has a 2.5mm cable for the stove-top (elements) and a separate cable for the oven. The replacement freestanding cooker I'm looking at has gas hobs on the cooktop and an electric oven (rated at 3.05kW). The equipment wiring (on the new stove) has a cable with a 15 amp plug connected so it would require a 15 amp hotpoint installed near it.

My question is can the existing wiring be used for this new cooker (using one of the 2.5mm cables) or is it necessary to install a larger cable (4mm or even 6mm) to make it code compliant?

Thanks for any replies.

Why are you installing gas?

CPU: AMD 5900x | RAM: GSKILL Trident Z Neo RGB F4-3600C16D-32GTZNC-32-GB | MB: Asus X570-E | GFX: EVGA FTW3 Ultra RTX 3080Ti| Monitor: LG 27GL850-B 2560x1440

Because we prefer a gas hob over an electric cooktop. The gas will be supplied fron a 9kg cylinder if we go ahead.

A 15 amp circuit is normally run on a dedicated 2.5mm TPS, so in your case one of your existing cables should be fine.

The reason for using words like 'should' and 'normally' is that this is the case for most residential / light industrial applications. if the run is unusually long, such as to an external building or perhaps > 20 meters a heavier cable may be called for to manage voltage drop.

It may or may not, there are other factors that influence a yes or no answer, get your electrician involved.

I guess my question re the why gas was more, why are you investing in a stove that the govt (prior to be fair), have indicated is fueled by a source they want to get rid of?

e.g. this https://www.safegas.co.nz/understanding-the-future-of-gas

From your link

"No. Natural gas and LPG will continue to be delivered to connected consumers until we’ve fully moved to new low and zero carbon gases, likely to be by 2050. "

Good luck expecting a 2024 appliance to last that long, hell I won't.

You missed the part about the price increases etc.

That's also a gas website so that's the "pro" version of the message.

And a health view of using gas: https://www.stuff.co.nz/environment/climate-news/127654901/gas-stoves-bad-news-for-household-health-and-the-climate-researchers-say

Have you tried induction?

Having had both I have a strong preference for induction. It just works, it’s fast and controllable, it only heats the pot and it doesn’t create moisture.
Gas gas to be refilled, creates moisture and CO2,
