High r2 in comparison to r1, rN

[Bizron]

Hi

r1= 0.51
rN= 0.53
r2= 1.48

checked terminations on most sockets, all good. Kitchen sockets grouted in couldn’t verify. Each of the back boxes inspected had cpc tags to back box, do you think that could skew results?

Cheers and thank you to all who reply.

Is it 1.0mm² or 1.5mm²?
No back box connection shouldn't alter the results
