[QUOTE="Andy™, post: 49489, member: 2012"] sorry - didnt see first post and kinda forgot about other post when i replied earlier! I first used the stuff working for a council. now working for myself, i have also used it a few times (when i can get hold of it!). i dont think BS7671:2008 specifically includes it, but it does state somewhere other BS stuff may be used - providing safety isnt compromised etc. under now under 17th, it cannot be used the same as SWA because it isnt earthed all round - part of it is neutral. so it has to be treated like T&E. for submains, in certain conditions, you could use T&E, but good luck finding 25/35mm T&E (and without needing a second earth). so your down to seperate tails & earth, SWA or split con. since split con is easier to use, and diameter is smaller againt same sized SWA, it can be a better choice. Also, DNO mostly use it because its much easier to work with than other cables - termination times are cut compared to SWA, so they are saving loads on labour kinda similar situation to BS8436 cable - IIRC, this was never mentioned in 7671:2001/4, but it was around and could be used (altho it was almost unheard of till 7671:2008) And final note, BS 7870 is as you mention. BUT, there is also BS 4553 - Specification for 600/1000 V single-phase split concentric electric cables. Cables having PVC insulation [/QUOTE]
