I'll just throw this out there.

When doing R1+R2 at the sockets what
Items do you use regarding leads or so.

 

[Eddy Currents]

Cross connect at the DB / CU then plugin the MFT at the socket

Or if you don't have one with your MFT you can use an adapter

 

[buzzlightyear]

I have got the adaptors all the gear. So came with a idea. So I'm waiting for the gang to tell me what they use.

I've been using these for a while now and find them good!

Kewtech R1 + R2 Jump Leads

KEWTECH R1 + R2 Jump Leads Kewtech jump leads are designed as a alternative to termination blocks used when testing and performing R1 & R2 tests. They significantly speed up testing time, and an essential tool when carrying out ring mains testing. Order Code: JUMPLEAD1 - LD1 #html-body...

I did see an Efix vid a while ago that had some magnetic ones that fitted in the cable terminal screw hole. Not seen or tried them though!

I have a (marked!) 3-pin plug with L-E link in.

 

[SparkySy]

Ah I have a breakout 13a plug like the one @Eddy Currents posted above and then a short patch lead with 4mm banana plugs on each end for such tests. Like these below but from cpc, just can't find them on their website atm.

Failing all else...
Rub the lamp. A wet-pants appears. Get him to wire up the last socket. You can pretty much guarantee a Live-Earth short.

 

[SparkySy]

Saying that a wet pants filled one of my sockets with water today and didn't say anything!
Didn't notice until I went to switch the cooker hood light on so I could fit the hob and it didn't work!

I have a (marked!) 3-pin plug with L-E link in.

I have used this method too which makes it easier for large boards, so all testing done at board while someone runs around with the plug
Also good for confirming circuit identity without having to disconnect anything

I have a (marked!) 3-pin plug with L-E link in.

Some of the croc leads would be handy, but hardly something I do a lot of.

The linked plug seems a good idea, as usually I linked L-E at the DB using some Wagos and then measured at the plug, but reversing makes sense and could well be easier. You can have a small fuse like 3A and null the MFT leads clipped to on the plug's pins for accuracy to remove the fuse's resistance.

Not that a younger me would ever have used a linked plug solely for blowing supply fuses at places I disliked...

 

[lozarus]

I go for the 13a plug with L-E linked out. I have another with L-N linked out (theyre lovely old bakelite items so they stand out and obviously labelled). I wrestled with finding an easier way to test - as some of our boards are busy to say the least.

Same. Labelled plugtop with 3 tails hanging out that can be shorted with a lever wago.

I do like these kewtech crocs myself the magnetic one looks good but can’t help but think the connection wouldn’t be as good especially after it ends up with metal filings all over the end

 

[LastManOnline]

My favorite.Plus I drill 3 little holes in the plugtop just above the L,N and E terminals.It facilitates other basic testing as well.

One advantage to linking out the far end of a radial circuit using a means that allows it all to remain assembled is that you can do IR tests first and then use the remote link for both R1+R2 and to obtain a reliable high current Zs:
Do IR tests (with CPC connected at board). Fit Link at far end.
Test R1 to CPC bar and get R1+R2. Assuming it's ok....
Test R1 to top of isolator (which is live) and get reliable high current Zs.
On a Megger the lead setup is the same for all of these tests, you are just changing a clip to a probe for the 2nd two and changing function.
