[QUOTE="SPECIAL LOCATION, post: 477679, member: 250"] You need to work the figures backwards.. AND.. remember the extracts quoted above are from the "INITIAL INSPECTION AND TESTING" of a NEW installation part of GN3... (e.g. NOT periodic inspection on an old existing installation section..) so if a new installation Global =20meg.. and you have:- 6 circuits this equals average 120Meg per circuit, Or one low around 30Meg + rest high 8 circuits this equals average 160Meg per circuit, Or one low around 30Meg + rest high 10 circuits this equals average 200Meg per circuit, Or one low around 30Meg + rest high 12 circuits this equals average 240Meg per circuit, Or one low around 30Meg + rest high 14 circuits this equals average 280Meg per circuit, Or one low around 30Meg + rest high etc.. etc.. etc.. Which.. For a brand new installation IMHO would suggest some dodgy installation work somewhere.? AFAIK the 20Meg Global is another rule-of-thumb to indicate if you need to stop and do further investigations. However... Personally I still like to know the exact individual circuit figures as well so I can calc OR measure Global! Guinness [/QUOTE]
