Domestic RCD tripped and wouldnt reset cause was a blown low energy light bulb.
There you go now for yours !

When I am wiring a socket on a ring final I WILL always sleeve the cpcs separately, I will connect the two from the cables (ring) into the terminal on the metal box. Then I will always have one cpc from that terminal to the earth terminal on the socket and when one wire is being terminated, I always double the end over.

I agree with Trev. I've been 'in the trade' all my working life (& I'm 60 now). I always take the cpc's to the socket terminals first & loop out to the metal box. Over the years the earthing/bonding of the metal boxes was relaxed. In my opinion, if one does it the other way round and a good connection is not made on metal box terminal, the earthing to the socket could 'fail'. I reckon that it's better to lose the earthing of the box than the earthing of the socket
If there are two earthing terminals on the socket would you use each one ie. connect the cpc of one ring cable to one terminal & the other cpc to the other?
I still think connecting both cpc's in the one terminal makes more sense. I use the same reasoning (as earthing box) because if one bad connection is somehow made (or wire broken) then continuity of ring cpc could be compromised.

I always put both cable CPCs in one terminal on the socket with a loop out to the box.

I'll admit i tend not to loop to the back of the box at all...only time i do is if it's a metal clad surface backbox...since they relaxed the backbox earthing. CPC's are always seperatelyt sheathed and then connected to the same earth terminal though.

The same earth terminal is fine IMO. Unless its for high integrity earthing!

Although I always put one in each and then a tag off one.

As for going to the back box first. I'm not keen, as said above. If you have a lost connection the socket could be used with no CPC.......

A kitchen that has had under cabinet lighting fitted by a local electrical company.
The only bit I opened was the lid to the J201, so they used a J201 for the neutral and wagos not in an enclosure for the rest... WTF?

12 volts?- still ,i can,t understand why the installer did that--
probably a boy left alone, non supervised, or a clueless idiot

Each to their own but I see that as incredibly bad practice.

I wire one leg of the rfc cpc to the backbox then the flylead from the backbox and the other leg to the socket, all individually sleeved of course. Just makes an easier termination IMHO.

Ok..... I'm glad this post had gotten some attention. What I always do, which I see as the failsafe option. Is to wire the ring cpcs into the socket together, then a single out to the box. It's good to know that these posts are getting read and are being paid attention to.

Here are some DIY faults which I found recently when I fitted a new kitchen.
1)Yes one of the water pipe was leaking, onto the spur from a spur from yet another spur.
2)JB behind the oven with 240v going in with T+E 1.0mm, 240v going out via flex, to each under unit light with built in Transformer.
3)Spur to a FCU using 2.5mm T+E from a 40 amp cooker circuit wired in 6mm T+E
The kitchen has been totally ripped out and renewed.
