Calculating r1 from R1 + R2

[The Ghost]

theoretically what would it be isnt it devide by 4 to R1+R2?

Go and look at post 2 except substitute 1.64 for 1.67. Then read and re read until it sinks in also look at GN3 around ring final circuit testing. It is explained perfectly in there. But yes you are right "little r1+little r2"/4 should = R1+R2 I presume you mean Ze was 0.12? I mean you do know that little r1 and little r2 and little rn are the end to end measurements on ring yes? Sorry in advance if that sounds a bit rude it is not meant to be.

Hi Mike, apologies for stating the bleeding obvious ... this RFC can't run a 32A breaker due to Zs > 1.1 ohms,

I hope your not trying to find r1 + r2 from loop testing for the cert
