Electric Oven / Hob

[Deryck Tintagel]

The current installation is gas hob / electric oven. The oven is supplied from the CU via a 40A MCB to a 45A CCU with single socket - the single socket has the gas igniter plugged in. The CCU is mounted in a cupboard alongside the oven

The new installation is for an electric induction hob and electric oven. Now, both appliances require 13A plugs so am I right in saying that the CCU can be changed to a 2-gang socket (MK for example) without need to change the MCB as this is protecting the existing fixed cable?

What are the Ratings of the Hob and cooker? Most double sockets are rated at 20 Amps , Diversity will probably help though.

Right I think I have got to the bottom of this (It's friend's daughter's new equipment)

Oven
Hoover HOE3051IN
2.2kW

Hob
Hoover HH64DCT
6.4kW in total

Oven will be fine on a 13A plug

The hob will need to be hardwired to the CCU. The instructions I had been told said to connect to a plug / socket, but reading the installation instructions on line it states a 2.5mm CSA flexible cable HO5V2V2F should be used. I think it could get a bit warm using a 13A plug!

Where is the present oven cable actually connected?

Some induction hobs can be configured for 13A, 16A or 20A however don't think the Hoover has that option, also some can be used single phase or split phase or three phase I think the Hoover does have that option which may have lead one to believe at first it would run on 13A.

However seems it needs a 20A supply so will either connect to a cooker connection unit or direct into the isolator although cooker connection units will have cable clamps some times there are no clamps in the isolator so it may need a cleat of some type.

Although some two gang sockets are rated at 13A each, they don't always have that rating so would not use two gang for 3 kW appliances I would fit two single sockets, although it now seems it needs a socket and cooker connection unit.

One thing to consider is cooling, a 13A socket well more to point 13A plug has a fuse in it and will get hot, so is designed to be in free air, some oven carcasses have the oven cooling fan vent through carcase so having the 13A socket inside is OK, as it is fan cooled, but 13A socket should never be inside a cupboard as the plug could over heat.

What is the minimum size enclosure, cupboard or anything else, where a plug may be fitted?

The existing oven is connected to the CCU in a cupboard next to the oven as far as I am aware. I have not seen it so I am going on what I have been told and anything else would be guesswork. Is there an issue that needs to be addressed?

Then you can use that CCU for the hob and plug in the oven- if the information is accurate and I have understood correctly.

Thanks for the confirmation. Just a lot of confusion in the instructions to use a plug! I know some hobs can use a 13A plug but I wasn't convinced until I saw the manufacturer's information sheets

I think those instructions may be suffering from internationism/translation. Where it talks about plugs, it talks about ones which are 'appropriate for the current' - which, as you realise, a 13A one would not be (and there's no sensible alternative in the UK).
