Zs-Ze = R1+R2 - doesn't it?!

[Marcus Vaughan]

Marcus you don't have to disconnect at the DB to do the cross connection/figure of 8 test - just do it at a socket with both ring legs in it.

Dave - sometimes I can't see the wood for the trees. Brilliant and simple at the same time. Thankyou. To me it makes sense to cross connect at the last new socket going in - and test at the consumer unit. I could always do a quick live Zs test on this last socket once it's in to ensure 'all is good'.

op have got a onsite guide!

Sorry?

I'll just carry on as I think I should - if I add a socket to a Ring Final then I'll go for the full cross connection R1+R2 test (and Ze/polarity). Remove the doubt. It takes a while though. It's just that background feeling of not wanting to disconnect the circuit from the consumer unit unless I have to. But that's what I'll do!

read the on site guide if you have one, it will show you about testing .
