right thing re cooker and hob

[Engineer54]

All that was needed here, was a twin cable connection unit under the worktop to connect both Hob and Oven to the cooker control unit, ...Job Done!!

What he needs is one of these:

Click MODE 45A Easyfit Dual Appliance Outlet Plate

Went to a job yesturday.

6.6kw 4 ring hob and 4.2kw cooker were both supplied on same 6mm on 32a breaker!! Both still using the 1mm flex pre-wired to them.

Running in another 6mm was not really a option as tenant didnt want trunking!

So kept the original 6mm and put that into supply side of 45a 2g cooker switch and a new bit of 6mm from load side to ccu, then ugraded the 1mm pre-wire to a 6mm from ccu to the hob.

Then as the 1.5mm pre-wired flex couldnt be disconnected from the cooker and there was no way a 6mm would even get in the small hole of the cooker, i left the cooker on a 13a plug and spurred off of ring with a 13a sw fused spur above work top and a single socket below for cooker to plug into to.

I know the cooker can pull u to 18a, but with diversity taken into account all the above is ok right?

Cheers

Beings as the oven and the hob came pre wired with flex do you not think that the manufacturers know that the flex they've chosen is adequate for the loads of each appliance? One would assume they didn't just use up what they had kicking about in the factory! Why would you think you know better than them? Then you have spurred off the ring for the oven when all that was needed is as has been mentioned above, a dual connection unit from the already installed cooker circuit! Instead now you've put extra loading on the kitchen ring and cost the customer more money than was needed!

Hi Joe
Don't get too upset. You asked for opinions. They are just a bit more critical than you expected.

Keep in mind that the current capacity of a cable is down to the temperature that it's going to run at at full load. The flex is certainly high temp (90c ?) whereas your T&E is 70c.

Well your damned if you do and your damned if you dont. Another example of we must follow manufacturers guidlines. In this case they come with a 1.5 mm flex, we do the calcs and not happy do we change. Then if something bursts into flames, you know they will say why change the flex. Very similar case a while back about manufacturers guidlines about fans being 3A fused. We certainly have this grey area, and hence the amount of oppinion posted here.

Going to track this see how the majority see it.

better still buy gas appliances. at least when you can't get an answer, you can put your head in the oven. make sure that there is credit in the gas meter first.:49:

It's a bit different changing the factory fitted flex than to change the moulded plug top!! A manufacture isn't going to fit a flex that is not suitable for the load of it's appliance, no matter what your own calculation come up with!! I keep saying this, ...the max connected load (as is always quoted on the box) is not the same as the max working load!! There is always at least one element that can't be used at the same time as the main element, for example grill/toasting element!! Generally the manufacturers flex will also be 85c to 90c rated!!

As far as fans are concerned, any fusing will relate to the flex/wiring connecting the fan to the buildings electrical installation, not for the protection of the fan itself!!

My view on this matter is 'always follow manufacturers instructions' and I doubt the instructions said 'we have installed the wrong flex on this appliance to catch you out, please install the correct size'........sorry, I'm too sarcastic

That's not possible on this forum.

That's not always possible either, and more and more these day's, many of the manufacturers instructions refer/relate to European wiring methods, that in many cases don't bide well with the those within BS7671!!

Everyday's a school day

 

[Richard Burns]

The wiring instructions on a light (from John Lewis) that I have just fitted state, all electrical connections must be well wrapped in insulating tape. I did not follow that one!

However I would never replace an undamaged factory fitted cable to an appliance.

Ha ha, it really said that ?

I installed some lights for my dad which he had bought from B&Q, they were the same

Loads of cheap sh*tty lights say that. I generally use the "instruction" sheet as a hanky.
