R1+R2 of a ring circuit

[Ste69]

as long as all the points actually on the ring were stable..(to within 0.05 of ohm)..then yes...

let us not forget that your looking for a suitably low reading of (R1 R2)....as long as it concurs with the r1+r2/4 equasion

the whole point of (R1 R2)..is to prove theres CPC available at every point on the ring

so Ste69...:
can you tell us please how many stages there is to ring final testing (low ohms)

end to end i.e L1 to L2, CPC1 to CPC2, N1 to N2 this is you r1,r2,rn, then calculate r1+r2/4 this should be the same as your R1+R2 readings.

Connect opposite ends of the cables i.e L1 to N2 and L2 to N1 (go to each socket outlet and test), then L1 to CPC2 and L2 to CPC1 (go to each socket and test again, as long as the readings are good and similar take the highest as your R1+R2.

while doing the above you can check polarity of the circuit

so 3 stages.



and if one of the outcomes is proving theres a CPC available at every point served....can you tell us another outcome?

That all the sockets are connected correctly in the ring by having similar low resistance readings? and also if there are any spurs.

answer here please:

IN BOLD

they you go mate, let me know if im right, if not let me know were i went wrong.

cheers

your also confirming that there isn`t a "ring within a ring"

oh...and get used to putting R1 R2 in brackets...like this:

(R1 R2)...

 

[Ste69]

will do, cheers again.

You're a wasted talent! After all that 'teaching' you must be a prime candidate for a senior mentor in the trainee and DIY forums

tha`s more chance of plattin pis than gettin me to teach any of them DIY turnips owt..

may....just may go into the trainee section for a look round though....maybe....
