Adding a super-simple electrical circuit to garage

Lockhouse what is the benefit of setting up a ring for the sockets rather than having it just a spur?

If it's just a spur you need a lower rated fuse in the fused socket, so you don't keep tripping the ring main you're spuring from if you've got a dodgy socket in the garage.
For lighting I thought it was 16amp supply and only 32 for power.
Then there's the different thickness cabling used for lighting than sockets.

A seperate ring in the garage is great if you want to disable the lighting ring but leave power sockets working or vice versa.
Plus as mentioned, you don't loose your house electrics if there's an issue.

You could do the lot properly yourself for £100. But you should really get it done by an electrician for the insurance sake.

The garage consumer unit Lockhouse linked to is 16A + 6A MCBs so would be OK to have the sockets and lighting circuits on spurs respectively. A ring for the sockets would in theory mean you'd be OK with a 32A MCB in the garage consumer unit but in practice still limited by the upstream protection device. Also it lets you say "if a job's worth doing, it's worth doing well."

I could have just run spurs but I wanted to have lots of points so actually a ring main is much tidier. Plus there's the satisfaction of doing it properly. It's been running nearly 18 months and the only time it's ever tripped was when the lathe developed a fault. i.e. when it was supposed to.

My garage already had a mains feed from the main consumer unit but I wanted to add lighting, I read up on regs/ best practice and the advise said it was fine to run lighting off a mains spur but you must put a fuse between the socket spur and the light switch.

In short you only need one feed for both mains and lighting if you do it this way.

My 2 sheds and greenhouse have been wired up for years to an extension socket with no problems at all. I have made sure that the wire is securely buried in a pvc pipe underneath paving slabs though, sticking it where you can accidentally put your garden fork through it is not a good idea.
