Radial off a ring circuit

[Gringoking88]

Hi all,

I have been asked to add a couple of sockets and add power to an existing strip light (currently disconnected) in a garage. There is presently an SWA 2.5 mm cable that is apparently live but taped up, hanging loose in the garage which is fed from a 32a ring circuit located in a utility room. Before you say it yes I know that is madness to leave a live wire like that but it was nothing to do with me (it really wasn't)!

I called the NICEIC just to clarify the RCD situation and was advised to add a garage unit with RCD protection and use two 6amp breakers. My question is why do the breakers have to be limited to 6amps, e.g. I get in effect it would be like having a spur but dont understand why I cant have larger breaker?

Please go easy as I'm just trying to educate myself.

Thanks in advance.

firsti'd see if there was a spare way in the house CU, then a better solution would be available.

I have to ask, you are listed as a DIY member. Should you be carrying out this work ?

Hi Tele,

The issue is the SWA is buried in concrete and I dont have the option of feeding it from a new breaker e.g. in effect creating a new circuit as the home owner does not want any disruption to their home.

Think NICEIC is the clue to your dilemma, anyway you are down as a trainee yet a DIY post???

Andy,

Thats why I asked the question, as I want to understand the full methodology behind their recommendation. I am pretty sure it is a simple answer and probably something I am just overlooking.

Is the supply fed via a FSU? RCD protected? and a bit of advice gain access to the trainee section, you will get more help in there

So, are you a DIYer or an electrician ? I'm still none the wiser.
