I was adding a new socket to the living room, as there was only two in the room. I split the ring main and added the additional ciruit. The cable was taken under the wooden floor boards.  To the other side of the room. Then inbedded in the wall to where it was terminated in its new socket. I wanted to go for overkill so I selected a cable which had equal to or better then the current carrying capacity of the normal 2.5 T& E and a one at that time I thought was easier to manipulate, and was protected against inviromantal effects ie the cable lying in wet soil under the floor. The cable more expensive and was flex type.

This for years has served well. Until an inspection and test was carried out on the property and as it was a flexible cable it was failed out right. Why ??? I was taught that if you wanted to you could rewire your house out in busbars if they were capable of carrying the current, and you could aford it. Can some one give me there educated point of view please.

For a start, you are not meant to place a stranded and a solid conductor in the same terminal.

If you had a socket such as the RRP crap, then these have two terminals for each L N and E, and you could likely get away with it.

Wiring fixed wiring in flex is a 'dirty' practice even so

Stranded cable is fine.�It's the flexible cables that should not share a terminal with cable.

This has been a big ish issue recently during inspections, and Ashley Rock have bought out a new JB to overcome the issue when doing downlights with transformers with flex ends. They are nice and thin, have cord restraignt, 4 sets of terminals in a row similar to pendents.

cool, thanx lec and chubby

Thank you CHUBBYPHASEWIRE for pointing me in the right direction and putting my head back in the books. I have now spent a lot time trawling through the Regs and am hard put to find where it forbids the use of flexible cable for fixed circuits. To the contrary. Now I am led to believe that the data concerning the cross sectional area of cable given in the Regs, after all the calculations are worked out for the given circuit, give the minimum size of cable that can be used for that circuit.  - Yes?     One could then, if rich or mad, decide to use a larger  more expense and less cost effective cable to complete the circuit in question. (Predicting  the IEE 21st edition). In interpreting  521.9.1, see below, I believe that if the used flex was superior to the 2.5 twin and earth. Then  the  (521.9.1). below criteria of  the regs was met.

Regs 17edition  (page 98) (521.9.1).  A flexible cable or flexible cord shall be used for fixed wiring only where the relevant provisions of the regulations are met.


Regs 16 edition  (page 77) (522-08.06).   “A flexible  wiring system shall be installed so that excessive tensile and torsional stresses to the conductors and connections are avoided.”

I haven't found anywhere in the Regulations, Yet, that prohibits a stranded and a solid conductor in the same terminal.

What a Pandora box.
Electricians are governed by regs. Yes! But these are by way of default deemed to be the minimal acceptable standard and what electrician worth his salt wants to measure himself up to the “acceptable minimal standard” .

Lectrician thank you. I will look around for a suitable joint box to segregate the wires from each other.

Many thanks looking forward to peoples replys thank you all.

ha . Now thats what i call thinking outside  of the BOX .
cool

Good or bad thinking Squirrel?

Good point
