We had a call-out today from a client to look over a new property they have bought. They needed to know how much work was required to bring it up to BS7671:2001.
Anyway, our Sparky was doing the PT&I and found that the lights, upper and lower, were both RINGS!!
The cooker, was a RING!! in 4mm T&E...but oddly complies with the Regs as the overall circuit rating is adequate for it's use and the use of parallel conductors is permitted!
The Building failed in some ways..the lights, although a ring, have no earth core as they have been wired in 2 core flex (0.75mm)
Each socket appeared to be a Radial, until he lifted the floor to see which ones were connected to what, and discovered that the ring was feeding two JB's, that were linked together to form the ring, and the sockets on the upper and lower floors were spured off the JB's!
The Earth's were connected in the sockets, unsleeved, but not all were connected at the JB, and those that were had been simply twisted together outside the JB with no sleeving.
The supply to the garage was a piece of 2.5T&E clipped along the back wall, but it came off a 40A BS3036 fuse (Yes it had 40 fusewire in it) and fed about 10 sockets plus the lighting in the Garage and the garage door motor!
The Guy that lived their was into DIY apparently..but not too good at it..he put in the kitchen, which is falling apart, the plumbing needs replacing almost in entirety from all accounts..
But it struck me when I was told the lighting was a RING..cos a lot of people have posted here and called it a lighting ring, when it is not..Mad world!
