Change of electrics required for new oven?

[ban-all-sheds]

I believe he has given his answer in my post from 9.24pm sir...

Where does he say that a B32 will not provide adequate fault protection for a 2.5mm² cable?

 

[ban-all-sheds]

radial circuit 2.5mm cable

Indeed.

Will a B32 will not provide adequate fault protection for a 2.5mm² cable?

Tbh I’m no electrician obviously

This is just what a couple of napit guys have both said

Change the 32 to a 16.

Does Anybody know where I can get a 16 amp breaker for my consumer unit please?

Pic attached

I’m going to supply to a friend who can do the whole thing for me

- change 32 to 16
- connect single oven up to existing fcu
- spur off socket to provide socket for microwave

You should get one.

Not ask a friend who is also not one.

Search eBay for

Mk Mcb b16

Just about the second most common MCB known to man (and woman).
If you don't know where to get one, just give up now and follow BAS's advice post #65

Thanks Andy

My friend is an electrician - but not private

World to Service an apartment full time so asked me to get the part

Haven't read the whole thread but I'm a fully qualified electrician. What is the wattage of your new oven? The microwave on a 2.5 is no problem. It will be on a 13amp plug top. Ideally it's two 2.5 radial circuits so it should be on a 20A MCB maximum. Most cooker circuits are wired in 6mm

It will be on a 13amp plug top.

Don't forget the bottom of the plug too! LOL

Hi mike

The oven I bought is 3.2kw

I’ve had the old gas oven disconnected .

Will have single one connection to existing fcu. That’s on a 2.5mm radial and change breaker from 32 to 16

I will then spur off the kitchen socket ring (-also on 2.5mm) and make a plug for the portable microwave

433.3.1

Most cooker circuits are wired in 6mm

a 4mm cable that SPLITS INTO 2.5mm Cables for some reason

 

[Michaelsf90]

3.2kw is 14A so your about right on a 2.5. That seems low power for an oven tho to be honest. The microwave will only be pulling about 5A. I'd stick it on a 20A MCB and see how you get on. The cable will be covered and from those wattages it shouldnt overload

Oooh, you tinker, you!

And yes I forgot to mention sorry - that from consumer unit - there’s a 4 or 6mm cable for about 1 metre that then splits off into

the 2.5 kitchen ring cable

The 2.5 radial oven


Why it’s like this I don’t know. The napit guys I had round said the person who converted the garage was probably not a sparky but “knew” some electrical stuff and was able to keep it going


Based on this - would you still say 20 or 16 mcb to replace the 32??
