hey people,
Ive got my c&g 2391 test and inspection exam at 1 today, im all ready to go except im confusses about one thing.
Continuity of ring final circuit condutors
When carrying out step 3 which is connecting the live (line) and the cpcs together on a ring main to carry out the figure of 8 test to check for interconnections ect, you are getting your R1+R2 reading, do you have to divide this reading by 4? im getting confussed one book says you do and another there is no mention,
do i just put down my reading for R1+R2 on the test forms. then if i want to work out my zs, i then have to divide R1+R2 by 4 then add my ze.
Thanks for any help in advice
