Cooker Regulation

[RGawley]

Hello,

I have a queerie if someone could help, recently wired afew houses & now the client has requested we do away with the cooker outlet & directly install the cooker to the cooker switch, is there a regulation for this? the reason he wants to remove the Cooker oulet is the type of cooker the client has supplied.
Personaly I see the Cooker as an appliance & not apart of the Electrical Installation. Any thoughts?

Also is it acceptable to replace the main switch in a consumer unit to a 80A/30ma Double pole RCD?

only if it's a stop-gap to make the installation safer pending a CU change--- division of circuits. that RCD trips through a fault on an outside light, the whole house is down.

If you're planning on adapting an earlier edition CU to the 17th you need to have a good long think about how you're going to do it, given the price of halfway decent CUs now it would be a lot easier to swap it for a shiny new one.
I can't think of any cooker where this would be necessary except for a Baby Belling which would just go on a plug top. Leaving it on the outlet is a far better option I'd say.

Thank you for the information.

Yes that's true best practice is to leave on a outlet, however there was a thread a while back with a guy proving that you do not have to have local isolation for the cooker if you look it's on here some where but best leave it in I think

 

[simpson93]

fine imo seing as you still have isolation at the switch.

In the ideal world you wouldn't do that. RCBO's is a far better way to go.

I thought the same mate but didn't want to spoon feed. I have enough of that with the grandson

BS7671 can be taken as the minimal requirements, it also contradicts itself all over the place, but that's another storey!! Commonsense and sound electrical practice will tell an electrician that providing a means of local isolation, especially to a fixed high power draw appliance is virtually always the way to go!! Far too much of this penny saving mentality going on in the electrical installation game these days. Funny how domestic CCU have always been continuously used for over 60+ years, but nowadays, even as the KW ratings steadily go through the roof, you get these plonkers stating, don't need a means of local isolation, just use the fuse or breaker in the CU!!

If it was my property any electrician with that mentality will be very swiftly shown the door!! lol!!

The op appears to be asking about doing away with the connection plate not the switch. He is asking if it is ok to take the cable direct from the switch rather than having a connection plate behind the cooker.

If the cooker or oven/hob is intergrated then no outlet required.. If its freestanding then a oulet must be provided.! An accesible isolation switch must be in place at all times

Out of interest which reg is that? A new one on me.

That said, common sense says its the thing to do!

Sure it's Okay, I think the vast majority of domestic cookers are directly connected to the CUU, certainly most of the older installations anyway. The usual installation was a 7/044/6mm T&E in a 20/25mm conduit out of the CCU into a single back box behind the cooker, and out through a grommeted hole in a blank faceplate to the cookers connection box.... When i first came into the industry i don't think there was such a back box connection plate, ...they came along quite a bit later!! In fact if i remember correctly, the first cooker cable back boxes were conduit stop-end Beasa boxes with metal box lids with grommeted holes.... lol!!

Just easier with back boxes. Reason, when customer moves and takes cooker with him, it will get disconnected at wall plate.
How many electricians have gone to properties to reconnect a cooker up for the new customer and found the cooker cable which was directly connected to CCU cut off as it emerged from the wall!!!!!
