So I've got my 2391... and was always taught and was under the impression that when carrying out R1+R2 tests on all circuits you must carry out the test at all points on the circuit, not the furthest point or a selection of points, I thought the test was to A. Prove a earth path that is suitable and B. Check polarity!

However one of the guys on the firm I work for yesterday has a grumble I was testing all points because it was 'taking too long' should I ignore him and carry on doing it my way or am I doing it wrong

Cheers

you're doing it right. test should be done at all points, otherwise how would you know if a cpc hadn't come loose in back of a socket. sadly, in this day and age, it's all too often that speed and price come second to quality.

Thank you for your reply, I dug my heels in when he mentioned it, I'm just there to test there work so I dont want to miss anything
 
Are we taking eicr or new installation

If I have wired the circuits in question and I know the furthest points I would only test from the board at that furthest point

i also would consider testing only at furthest point only if i had wired it all myself.

I only ever test R1+R2 at the furthest point on initial verification, and carry out a Zs at all (accessible) points. There is little point in carrying out both tests at every point. Although you could of course do it the other way round. By accessible I mean if a connection is a pain to access I wont do it, although if there are exposed conductive parts I would likely do a quick R2 check with the wanderlead.

If its a pain to access then isn't it more likely that there may be a poor connection which needs to be found?

Why does it matter who wired it, we all make mistakes which is part of the reason we do initial verification testing, or are you magically immune from making mistakes?

i did say consider. all would depend on time factor and cost .
 
I was taught to test R1+R2 at the furthest point, the theory being if you test at the most furthest point on your radial circuit and get an exceptional reading it means there are no breaks in the line or cpc.
This is how I was taught.
 
do the guys who have done the wireing do testing as well....if not..tell them to stick their noses elsewhere

Think this video will / or should dispel any misconceptions on how to test an RFC

Measure at All points and record the highest as the circuits R1+R2, regardless if it’s not the last point such as the strappers forming the 2 way lighting to the landing light and switched both ways.
