7. 3 kw INDUCTION HOB

[Angefoh]

Can I run a 7.3Kw induction hob off of 2 x 16 amp circuits single phase I'm not sure what size cable is installed, I will check.
Would I be be able to run with the 2 x 16amp breakers or should I install a single 32 amp breaker with separate RCD?
Thanks in anticipation.

Get an electrician in mate. He will advise you on the correct way to install such equipment

Running things dual phase is pretty unconventional over here

I will do so but I just wondered if the existing circuits were enough, other wise I will get a larger cable, which I can at least buy and run myself without paying electricians fees initially.
But thanks for the reply

Many Electricians will not connect wiring which your have done and will insist on running it again themselves.

OH really, OK I suppose safety and regs come into play. Still doesn't answer my question regarding existing installation though. But thanks.

The 2 x 16 amp feeds are on a single phase just separate breakers. Thanks for your reply.

as a general rule, a device shouldn't not be run from 2 different breakers unless they are physically interlocked so they trip together.
there are some exceptions but they are unlikely to come into play for your Hob.

Hi James, thanks for the reply. I know that the electrician that installed the 2 circuits was providing for an electric hob which I think do run one set of of rings for each circuit. Should I ask for a single 32 amp breaker to be installed?
I still need to check the size of cable he has installed.
I'm basically wondering if the existing wiring will handle the load?

Rings? I don’t think so!

 

[Angefoh]

Rings? I don’t think so!

By Rings I mean ceramic hobs. But do they not run on separate circuits????

Fairly common in my part of the country, where there are loads of two phase farm supplies, but agree that it's unconventional for a domestic supply.
Unconventional doesn't make it wrong though, so I can't think of a reason to say it definitely shouldn't be done, although the MCBs should be a DP and the isolator a TP.
This all assumes that the hob is designed, like most modern ones, to be run from a three phase supply, and is supplied with links for the UK market. Two of the phase terminals would still have to be linked, so checks would need to be made that the max demand for these two didn't exceed the supply capacity.
Unless it's difficult or impossible, it would still be a lot simpler to fit a new supply cable of sufficient size for the hob.

It's more likely to be one for oven and one for hob.

Do these feed into separate switches/points ?

You still need to look at cables sizes.

The short answer is no.

The oven is on a separate breaker and the two other breakers are marked electric hob 1 and electric hob 2 . I need to pull out my cabinet to see where the cables/outlets are positioned and what size cable is provided. I have a feeling that there are two points and I wired into one of them for my gas hob ignition but that was 6 years ago so everything is a little hazy.
OK thanks for the reply.
