Guys thanks for all the discussion. Really helpful and appreciated.

Ban-all-sheds. I notice you have not said if it is a IEE Requirement that these isolators are 'on show' or if it is that they must be easily accessible. Other threads seem to imply that to have the isolators fitted in the related cupboard is perfectly acceptable. What would one be expected to do...

I am having a small domestic kitchen wired and have been told by one of the sparkies quoting for the work that the isolators for the single convection oven, hob and hood need to be at work top level for easy access. Particularly for disabled people. Is this now a regulation requirement or...

Simply it leave the walls freer for putting spur shelving supports on looks neater and if generally less likely to get in the way.

BS 3036 I am continuing to think this through. 1. I could shorten this ring further by putting one or two of the sockets on fused spurs. This might bring the total length within the 84m allowed and could then remain protected by the 32A MCB. Would the the voltage drop on the spur would then...

BS3036 You are being incredibly helpful. Thanks. I understood some of your requirements, but have been unable to obtain the disconnect graph as the Type 1 is no longer available. For the moment I am unsure of most of the rest, but could get it ascertained. However, surely if one designed a...

I have done another measure of the amount of ring used so far in the bedrooms and upstairs landings and it could well be about 38m. Ideally I would like to use a further 54m in the garage. Total then would be 92m. Much of this is being used as drops as I prefer to do this, than run horizontally...

BS3036, thanks for that detailed answer which I have worked through to understand. You have said the design that I was intending is not allowed so again I look at just continuing the ring main. Using the formula (14.82 x L x I) / (1000 * 2) with the existing MCB rated at 32A I would get a ring...

That was not clever missing out the web link:- http://www.kevinboone.com/cableselection_web.html

Have a look at this extensive article, right at the end in the Appendix, Table A12. 2.5mm2 ring on a 32A MCB Type 1 is listed as Maximum length of 33m and 20A MCB Type 1 53m. Am I reading this information incorrectly?

OK , so I am learning how to use the forum. I did not think I would get any more advice on that topic so started another, hopefully with better understanding of the problem. Extending the ring I don't think will give me enough distance before voltage drop is a problem. That seems to be the...

I have a garage attached to one side of the house. One of the house ring mains serves two bedrooms and one socket in the garage. It is protected by a 32A MCB and a 30ma RCCB trip. Under part P I think I can add sockets but cannot go back to the consumer unit. I have no spare MCBs anyway. Can...

Thanks so far BS3036 and oharaf. I do have 20m cable allowance of the Ring Main that I can still use in the garage. Is there any reason why I should not just continue the ring main as I first intended with some additional sockets and put in some fused spurs for any remaining sockets that I...

Hi everyone Working under a building notice I have recently built a garage joined onto the side of the house. The inspector is aware that power sockets are to be installed and I am aware that I will need to get a helpful electrician to check any installation after it is completed, and a...
