[QUOTE="Doc Hudson, post: 483557, member: 1607"] High -vs- Usual? how are you defining these values? Something is only high if it is out of proportion to the cable lengths involved. e.g. I bought a round of drinks that cost me £25 do you think that is high? Maybe yes if there was only you and three friends, but not if it was a group of twelve old school mates? As you include no specifications of lengths, CSA of conductors etc.. not much anyone can say really. 'Usual' is only 'usual' if it is proportional to the cables lengths, and the tables in BS7671 can give guidance as to expected values for different lengths at various conductor CSA. You can't just expect every job to have the same values. Doc H. [/QUOTE]
