Is that some form of typo ‘it’s the house buyers that want to pay the lowest possible price’ have you tried buying one lately. Builders cut the cost to maximise profits not to provide cheaper housing for the proletariat !
If the combi oven came with a plug and didn’t have manufactures instructions to be connected and separately protected his ‘reasoning ‘ would hold more water. I holds less for me as the same load on the other oven is via a separate radial. Although this is obviously good practice and the norm to...
His excuse was that he thought the combi-Microwave was initially just a Microwave oven. But oddly he was going to let the installation remain when the item was correctly identified as a 16amp 3.65kW device.
His reasoning being it would rarely draw (if ever) the full load on the spec plate...
Agreed, but he's keeping the 2.5mm socket* and putting an isolating switch in the grid for it (unused but maybe in the future) but running an additional cable from the switch for the second oven and adding a connection point behind the oven.
*The plaster board is now over the wiring and it's...
Well, the compromise is that he is going to put the second oven on another 6mm radial from the oven switch. Is this a better solution?
Its still not a 16amp device on a 16amp protection but the radial is well in spec. even if both ovens are on.
Didn't realise you (domestic) could ring the NICEIC...
To the right are the b boxes for the hob and oven.
To the left the b boxes for spur from oven radial and M/W from ring final.
These are exactly the same loads.
He is an image.
The chalk ident 'M/W' is for thee combi oven 3.65kW.
Hmm, can see how to load an image from a file on PC, any help?
Thanks for the replies again EFL.
For clarity, this is a new build.
I was given a site visit and took photos.
From this this there were chalk wall markings. 'oven' looks to be a 6mm radial and 'Hob' (induction) an additional 6mm radial.
My interest was tweaked when I saw 'm/w' on one of the 2.5 cables from the 20amp grid...
I realise this question have been asked before but I still have found no definitive answer.
Unusually this is a New house build.
Kitchen ring final circuit using 20 amp dp switches to isolate the white goods (including F/freezer etc and d socket) on a 32amp CB.
All wiring 2.5mm.
Appliance: Oven...
