Please someone help this brain dead moron. For some reason my brain just will not differentiate between an exposed conductive part and an extraneous conductive part. This is probably an idiot question to you all but I seem to be tying myself up in knots over it. Heeeeeeelp and be nice i'm feeling very fragile

metalwork thats part of an electrical appliance and could become live (directly)is EXPOSED CONDUCTIVE PART metalwork which has nothing to do with an electrical appliance/installation which could become live (in-directly) is extraneous, ie a radiator!
Hurrah !!!! By jove i've got it I kept thinking exposed conductive parts were things like the metal body of a kettle for instance. I wish i'd asked last night now, i may have slept much better. Trouble is this forum can be quite intimidating for the newbies and inexperienced. Thanks General for the simple explanation and those links were brilliant welsh Onwards and upwards
I wish i'd asked last night now, i may have slept much better. Trouble is this forum can be quite intimidating for the newbies and inexperienced. That's true - But, THIS one isn't.
Sometimes it takes a while to get to grips with some topic or theoretical idea. But don't be afraid to ask clear sensible questions. Although you could have got your answer from the definitions section in BBB (BS 7671 page 22). Sometimes things need to be explained from a different angle for the penny to drop.

You may want to re-write what you've posted! Think about it.

yes my quick post/definition is strictly wrong to the letter, but i know what i was on about, and i believe a qualified spark would of known/interpreted it........ maybe i'll copy and paste for the less experienced next time! FORGIVE ME ANYONE OFFENDED!
the definition of an extraneous conductive part..... which is a part liable to introduce a potential, generally earth potential, and not forming part of the electrical installation......... me too LD! especially recently....see you try ya best and still get flack! :O
All I was thinking is that the rads may be connected to various items of equipment that are part of the electrical installation via copper pipe. Therefore making them part of the electrical installation in a round about way....Immersion Heaters, Boilers, 3 Port Valves etc.
cheers LD, but again different people DO have different opinions on these two conductive parts! we all know the earthed metal casing of say a kettle is an EXPOSED CONDUCTIVE PART an EXTRANEOUS CONDUCTIVE PART is deemed by some to be anything metallic which doesn't play any part in the electrical installation. others say its not EXTRANEOUS if isolated from earth by more than 50Kohms. others think this figures too low and raise it etc etc
