no mate,my nic bloke asked me the question the other day on my annual assesment and i couldnt remember thats all ,i think its about 480 metres,might be wrong.depends if its TNS, TNCS or TT supply, depends on installation method, depends on installaing to 16th or 17th (because of the voltage drop changes)
to be honest, with table 7.1 in the OSG you cant go far wrong
Do you want an answer to a specific question Paul?
hey paul from the osg ...32a mcb tncs type b ......84metres....
but wait for the new book they may give you an extra metre
