I work to BS7671 because thats relevant to what I do and to what most people do on the forum and for the Op this is probably the most relevant document for his situation, he can correct me if I'm wrong. On your project you may work to other documents thats fair enough but are they relevant to what I (and maybe the OP) do - unlikely?
I work to various Country codes and regulations, including BS7671. Most overseas project specifications will denote ''designed and installed to the highest international standard''. And yes they are relevant as All those standards will say exactly the same thing as far as parallel circuitry is concerned!!
Are you trying to imply I don't?
I was pointing out that that your statement was misinformed... I have no idea if you, or come to that anyone else here have a broad understanding of electrical technology, i was merely making a statement...
There are very few people who don't have to refer to the regs at sometime. The whole point of an EICR is to make observations and back that up with a reason which is usually associated with a reg no. No-one would be able to quote every reg number and sometimes you see something it maybe doesn't look right but when you delve deeper you find it maybe ok or the actual reason why it doesn't look right. In the case of the OP, he's seen something that doesn't look right, I'm just pointing to something that MAY show it is OK. What he choses to do with that information is up to him, he's the one signing the EICR.
I'm not saying you shouldn't use the Reg's as a guide, just don't be surprised that what your looking for isn't covered, or doesn't give you a definitive answer. So finding a relative Reg number to substantiate a defect observation isn't always possible.
But the thread has got nothing to do with this. I've already agreed that I wouldn't use different cables so what are you trying to prove? We all know you are knowledgable but sometimes your arrogance and intolerance of others just winds me up!
