Unknown Cable.

Evnin' All,


A customer of mine has supplied some of his own cable. It appears to be 2.5mm2 copper twin and earth. It has a grey tough oversheath, (difficult to strip) marked DESCO P. It has a bare centrally placed C.P.C. The live conductors are insulated with Brown and Black coloured insulation. No B.S. markings.


Does anyone know its origin or anything else about it please?

  • Hello Blen,

                           I would not buy or use unknown cable normally. The customer installed some of this cable to three double sockets in his dad's kitchen. I installed a new consumer unit for him initially. He then said he would do some D.I.Y. home electrics and could I return test and connect it up. He ran main bonding cables and I connected them. He also installed a new cooker hood with external ducting very nicely. I connected that up. He connected up a cooker switch with a 13 Amp socket on it. When I tested it I was initially confused as the main cooker switch had to be on to get the socket to work. That happens when you connect the feed into the load terminals. He had squeezed a C.P.C. hard against the neutral behind a single socket, the R.C.D. tripped. N to E short. I sorted that. He is a good all round D.I.Yer but is not up to being a good electrician. Perhaps that is why he called me in to check his work. He is a very nice man, and is trying to save his retired parents some money I suppose. All of his sockets now test out fine, so that is good. 


    Bye,
