Paul,Yes the old 7/029 was great to work with as pvc cable, not so clever when it was rubber though it was realy bulky then and as sometimes hapens now you could get bad drums where you could not strip the dam stuff. Strip the outer sheath and the inner cores would strip to the copper straight away. Oh happy days!
Re the ring circuit syndrome,realy many of the problems come down to lack of forthought on the part of the installer / designer.
Another problem that I can see looming in some domestics is the home office equipment on the ring circuit all stuck on the RCD side of the split load unit. Some homes now have a considerable amount of IT equipment, not uncommon to see 2 or 3 pc's hooked up to networks scanners printer fax's modems all spread around the ring all dripping a few milliamps to E, not to long before it starts to pop the rcd at the mains in ome cases!
Dave,
Sounds mutch like the u.k. we dont work for builders either you finnish up in all sorts of trouble with extra's and variations because they underprice in the first instance to secure the work and then you get all the hastle from the client because they think its you thats trying to put the minimum of equipment in to cut costs. Then there's the patment issue, Noooow I dont think we will bother thanks.
