Hi, I found this forum while searching for information about wiring up an electric oven. I realise I haven't searched the forum properly for my answers and I know that the golden rule is to search before asking, but I'm hoping to do this tonight so I thought I would post my plans and questions and hopefully get some feedback as I carry on searching...
I am fitting a 3450w/11,4kw oven (give or take a little bit,) with a gas hob.
With the existing oven being gas only I realise i have to fit a suitable radial circuit. Today I bought 6mm twin core +earth, a 45a control unit (with socket) and a terminal outlet box. I think all that is fine.
I had intended to buy a 40a mcb today (as thats what seems to be suggested) until the guy at the shop told me I had an older style consumer board and that it would cost me circa £30. I have a spare 45a mcb in the CU just now that would have originally been for a cooker.
Q1. Can I just use the existing 45a mcb and what are the effect of using an MCB with an overly high rating for the purpose. Is it correct to say there's a 10% margin that you can go either way.
Q2. I'm just away to investigate this more but I hadn't considered RCD/Earth leakage but read a post which suggests that where possible this should be considered with control units which have a Socket. Any input on this would be great
Q3. How can I figure out if i can run a kettle from that plug, Is it just a case of adding the ratings and ensuring it falls within the limits.
That's it for now. I hope I've provided enough information for some advice. I'm quite competent and safety conscious (with electric anyway) in terms of switching off etc and triple checking everything. I just need confidence that the hardware I'm using is suitable.
PS. The consumer board is a metal case, It has two rows of MCB's, A master switch and an RCD reset switch. The MCB's are MEM M6 Type 2's which, as i type this, I found out are Memshield. The CU is probably the same manufacturer but I am not home right now to check.
Thanks for any advice
