Garage Wiring Question

[Andyr86]

Hi guys,

Been asked by a friend to put a socket and 2 lights into his garage this weekend (weather permitting!) and have come up with the following plan:

All using single core cables enclosed in 20mm PVC Conduit. The garage is fed by a 15m long run of 2.5mm2 SWA (already installed) protected by a 16A MCB on the CU.

As far as I understand the current regs it is accecptable to have a light running off a socket providing that it is protected by a 6a fuse (in this case in the form of an FCU, which also provides control). Can somebody please confirm this to be the case?

Will I require a way of isolating the socket from inside the garage and if so would a seperate FCU be accecptable?

Finally, do I need to get this work signed off by a certified electrician?

Thanks for any assistance given,

Andy

Does the house CU have RCD's? Any particular reason for selecting singles?

yes you an take lights off a socket using a FCU but the fuse will be a 3 amp why weather permitting doesnt the garage have a roof ??

I was under the impression that if you are using PVC Conduit then singles need to be used? Would prefer using T&E as its cheaper.

Just me being a wimp . Will make sure to use a 3A fuse tho, thanks.

You can use twin and earth in conduit do make sure the socket is RCD protected , and the work is classed as a minor works so would require a certificate

If you don't know the basics like if it is ok to use a FCU to feed a light from a socket or if you need an isolator for a socket should you really be doing this work?

Is'nt this LABC Notifiable as well.

I agree with Specialist, this is a new circuit so therefore is notifiable. The O.P shouldnot be doing the work as he asks "do I need to get this work signed off by a certified electrician?"

If the SWA is already installed, and the OP is just extending the existing circuit, there is no requirement to notify.

My appologies, missed the SWA in the OP, one to many Jamesons.
