figure of 8 test

[Monkeyblaine]

Can someone please explain why we have to cross conductors from legs of a ring to perform figure of 8 test (r1+r2 or rn+r1) and why we can't just link those conductors from the same leg as it would also make a loop... Would I be right in thinking that you would get a more even reading across both conductors when connected in figure of 8. Rather than the way I said as it would measure a much shorter distance. And would give inaccurate readings?

This way you have proved correct polarity through the ring without an additional test.

cross connecting creates a big loop where all the sockets are the same distance apart, step 2, 3 prove polarity

 

[Monkeyblaine]

is that the only reason we do it in that way?

 

[telectrix]

not only that, but by cross connecting, all your outlets should give the same value for R1+R2, unless there;s a spur off the rfc.

As above, and prove not any multible rings.

As tel said, easy way to locate spurs and loose connections.
If you don't connect them to opposites they will go up as you go along the ring then back down.
Like your loop readings will.

yes beacuse the disatnces are not the same
