The FAST Way to Test Ring Main Circuits!

Testing a ring final circuit can be a time-consuming process. This new A2214 test adaptor from Metrel automates the complete testing process.

Joe Robinson demonstrates how to test a ring final circuit with this new adaptor works with the Metrel Mi3155.

I was using one of these about 10 years ago, haven’t missed it since going with other brands tbh

[rodderstrotter]

That looks like hard work
I’m sure I would of got that test done by the time you set up the and calibrated that thing

[andysims]

How times have changed. When I was an apprentice we tested a ring with a bell connected to a battery, testing end to end. And as I good measure we would then test for insulation breakdown using a Megger

[kimspence-jones]

The original reason for inventing ring final circuits was to reduce the amount of copper required for power distribution. That was a big issue during post-WW2 reconstruction. As copper prices rise and green footprint becomes more important, that reason becomes more relevant than ever.

Good job thanks for info 👍.I wish to get one of those mi3155 but I already own metrel lower version mi3100s.The question is, can this A2214 ring adaptor be use onto Metrel mi3l00s ?

[CarlCosby]

Great for initial verification, not required for carrying out an EICR. I’ve chosen never to install RFC’s in any re-wire I do because they’re pointless. Also, when systems start converting from AC to DC over the coming years, RFC’s and in particular the way we wire will change and RFC’s will be a thing of the past. Out of curiosity has somebody really wired that grid switch like that next to the socket??

[billsbasementworkshop]

Great, will this make me want to go out and buy a METREL, NO. I find it to complicated. Much easier to turn a dial.
When they come up with some way of doing it with the DI_LOG 9118, Maybe I might be interested. Thanks for the video.

Hi, I see on min 6:21 r1, rn, r2 readings can not be saved but how did you get the screen on min 6:57 where the r1, rn, r2 readings can be saved?
Many Thanks

Nope, it was called a ring main. They tried to retcon it as 'ring final' ... the term 'final circuit' didn't even exist when it was introduced. I HATE that people will say ring main is wrong. If a person can confuse the 11kv network with a socket circuit in a house, . that person has NO business being an electrician, or even alive

[Davidhughes]

Looks a nice test kit to be fair seems as good as the Megger and fluke.

[tombickerton]

Well worth the money . Metrel tester is on my list for my next mft . Great video

[martinsutherland]

I invested in the A1214 quite some time ago to go with my MI3152. It has red wires with heat shrink sleeving to indicate the usage. Strangely for a UK specific product, the line wires have grey heatshrink and black croc clips! The MI3152 has an auto sequence test which works with the A1214 but has no calibration option so the r1, r2 & rn results are not going to be much good. After getting readings at consumer unit, it gives the error IB020 and it is necessary to press another button to actually see the results. I took it to Metrel's UK office and left it with them for several months for testing but they did absolutely nothing and finally sent it back! Having just seen this video, I now know that there is a ring option in low resistance testing but this still does not have a calibrate option. I therefore upgraded the firmware (which deleted all my stored results) and after this, there is still no option to calibrate! It is hard to recommend this ring final tester based on my experience with Metrel - very disappointing!

Wow nice bit of kit, but I’m happy to do everything my self, Seems like an excuse not to use your brain and put pen to paper . People are to happy to let fancy machines do the thinking for them.
It is a nice bit of kit though
Shame the adapter is only available for the metrell, or is it
But who am I to argue i’am just a Humble spark who’s opinion means nothing.
Fantastic video as always Joe
👍👍👍👍❤️

When testing around the house with probes how do you know when to swap from r1+rn over to r1+r2?

[thattoolguy]

Been looking at doing a swap over to Metrel.. need to get my hands on one and see how the menu works.. i like the adaptor.. its a shame the leads aren't replaceable.. good video Joe.. p.s .. aint you finished that kitchen yet haha

[tongtawee]

Is this adaptor complatible with MI3152 EurotestXC ?

[bigashelectrics]

Looks good, hopefully an adapter is released so it can be used across all testers 🤞

[seanthespark]

Does seem a little long winded but I would imagine that it would become second nature and very quick once you got used to the procedure.

Questions...
Does it retain the highest reading?
Does it remember the resistance of the test leads or does it jave the ability to self test/store them?

Great video Joe 👊

[gbelectricks]

That mft, doesn’t seem very user friendly! yes, it probably is a time saver after you got used to it. Great video Joe👏

Very informative but the leads need to be replaceable on any device used professionally
