no, haven't dissapeared, thanks to everyone for your replies, that chart from old timer was exactly what i wanted, just a printable document i could put in my testing file. thanks again for the advice, i do have a green copy of the regs, an OSG and guidance note 1, but was after a printable copy of the table, again thanks very much for your help, regards, Ben roberts

As I say, if you have an iPhone then the "sparky" app is brilliant for things like that

For Maximum Zs on circuit breakers to BS EN60898 or BS EN61009 Rcbo's

Type B - 46/In eg 10A breaker = 46/10 = 4.6 ohms

Type C - 23/In

Type D - 11.5/In

Are you sure???
