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?

i thought it seemed high but the nic guy was very insistant so i thought it best not to p.ss him off by arguing with him over it.its not the sort of question you get asked very often in my experience anyway.
