How to Test an RCD - BS 7671 Amendment 2
Вставка
- Опубліковано 23 тра 2022
- Changes to BS 7671 under Amendment 2 of the 18th Edition of the Wiring Regulation requires RCD’s to only be tested on the AC setting regardless of the Type of RCD and at the rated residual operating current of the device. This simplifies the testing process so even if you have an A, B or F Type RCD you only need to test it on the AC setting of you MFT tester and at 1 x delta n (often this is 30 mA) with a maximum disconnection time of 300 ms.

Why does my meggar trip the Rcd on zs readings
@@simonbooth7802 my ethos tester has a low current test for zs readings which takes longer but doesn’t trip breaker, the other earth loop test i just use for ze readings as is faster (and no breaker to trip)
@@simonbooth7802 During a Zs test your meter simulates a fault between live & earth and measures the resistance.
If there is an RCD/RCBO in the circuit it detects the fault and trips. Some meters have a low setting which should avoid tripping the RCD.
@@simonbooth7802 What setting are you using for Zs testing?
Thank you for these dedicated instructions to electrical knowledge and equipment use.
Only the British can make something so simple seem like your going to the moon
Lots of armchair committee electrical experts dreaming up wacky ‘what if’ scenarios and keeping the industry in constant commercial motion.
@@MS-Patriot2 agree, the US is becomeing the same way with regulations
@@chainsawsandgenerators9952 UKs latest regulations have actually simplified areas associated with GFI/RCD mostly because they’d confused the hell out of the electricians who used to understand what they were doing !
So many European countries make their equipment look like it's for the moon he's not wrong LOL alot of unnecessary stuff (a lot of "faff" as they would say)
It’s the accent. A Brit on the job here in the US adds instant credibility to your crew.
short and simple. Thanks!
Excellent instruction
What the hell!!! Massive respect to electricians man. Have to say the British standard is next level. ! Looks complicated
That’s we’re the money is. 😅😅
Nice job thanks
👍🏻
I remember working in a museum as a apprentise and had a big yellow tester with a strap around the neck and I was asked to test the phases and I put the probes on the wrong cables and blew the entire tester up, it sounded like a box of glass and the electrician with me just laughed his head off and then had to explain it to the boss. I think it was around 800 pound
This is cool
Thanks man
Perfectly 👍
Do the test at the board especially rcbo much easier
I failed my am2 because I did not do the half time test first Gary. Gn3 stats half times then 1 X tests.
Thanks for the feedback
Why do you test all rcds as of they are AC type?
What’s the point of having type A setting then in megger tester if we only test on AC setting?
Any comment on why you haven’t done half times?
What's with the degrees??
So the rcd failed to trip in less than 30ms for 30ma test.
In your GSH video "RCD Testing Made Easier....?#shorts" you say all loads should be removed. This is also stated in the GN3 brown book page98 paragraph 2. So does the load include the cabling and should it be disconnected with the test done at the RCBO? With RCDs it was simpler as the RCD test could be preformed at the board with the MCBs off (although strictly speaking the neutrals may still be in circuit).
What is the Ul=50V during RCD test?
Whats max disconnection time for x1 is it still 200ms?
300ms mate
32 Ampere for A socket ?
where in the onsite guide does it tell you the maximum trip times?
Section 3
Does anyone know the model of this consumer box? Love the fact the led under each switch
Wylex
the protective devices are AFDDs, they are an additional level of protection and cost a pretty penny more than a regular RCBO lol
Or just put it on auto and get the 1 times and 5 times value together
I think that the 5 times requirement has now been done away with in the 18 th edition
@@roystevenson1375 idk I’m the apprentice you see but we record both one times and five times
@@mcoys1029only need x1
The 40mS disconnection is for 5x.
How are you showing compliance at 70ms?
@@crustyzimmerman3324 couldn’t tell you that I’m the apprentice we record the 1 times and 5 times at 30ma
Why not use the auto it records all results as you reset the trip switch
👍 why would you waste your time when you pay 2000 grand to test in auto lol 😂😂
Doorbell socket gaz?
Yep 👍🏻😀
Though so.. ive fitted loads of those BG ones.. customers really like em
The RCD is from Siemens right?
So why did they upgrade the testers with ramp testing?
To test for potential nuisance tripping
Never have seen such a test done in Europe. Is this a UK thing?
Here in Germany we do similar tests
BS7671 uk wiring regulations are some of the best and safest in the world. “HD 60364
CLC/TC 64 is the technical committee responsible for HD 60364, which is the European standard for Electrical installations and protection against electric shock. This is essentially the European version of BS 7671.”
In Malta it is mandatory to do these tests.
Damn my rcds dont have little lights on them I'm going to have to change them now
That's a AFDD integrated with RCD. RCDs alone do not have indication light.
What’s is full meaning of RCD
Recidule Current Device.
You going backwards ?
All change for Ammd 2!! Only one test...Don't need 0deg and 180deg..
Test at one times i Delta n as a minimum and for me in both half’s of the AC waveform 👍🏻
@@GSHElectrical indeed and agreed and for someone also who has been told over and over again during 16th, 17th and 18th, it seems a bit strange, now we only have to do one test on the RCD officially.
The reason for testing at 0 and 180 obviously is to ensure that the RCD detects and operates on either side of the waveform. But with 1x given we have a maximum operating time of 300 ms, if for example the fault wasn’t detected in the negative half, then there is time to ‘wait’ until the next positive half cycle to ensure compliant operation. Whereas at 5x and our 40 ms that becomes a little tighter once you allow for mechanical operation and where exactly in the wave things occur.
Similarly I have never understood why the Fluke does the 1/2 twice on auto. The test runs for two seconds, so why do you need to run it again starting a 1/2 cycle later…
whould you not test it at the board its simple enough and faster
$3300 meter ohhh myy
All that money spent and his half inteligent meter won't tell him what kind of connectors being used on the job.
I find what you guys in the UK do fascinating, but what really bugs me are the device-cover plate combos. What a giant PITA when you want to repaint… or for that matter when hooking them up initially.
Someone please enlighten me. Is the faster the disconnection time the safer the RCD?
YES! It has to do with impedance (resistance) of the circuit. If there's an electric fault, someone could get electrocuted; therefore, it is imperative that the RCD trips (disconnects) the supply of electricity fast enough to prevent severe biological damage. If the impedance (resistance) of the circuit is too high then the RCD won't detect the imbalance in time so the faulty current will keep flowing (and causing damage). If the impedance (resistance) of the circuit is low enough then the RCD will pick it up (relatively) instantly and trip (disconnect) the faulty supply. That is why your EFLI (Earth Fault Loop Impedance) readings have to be compliant.
@@kaizenanalyst4833 Shouldn't you be testing the RCD and not the circuit??
@@BakedTuber Yes, you are testing the RCD but that RCD would be on a compliant circuit (which you would've tested and confirmed as compliant upon initial installation of the circuit). And in fact, on pg 95 of Guidance Note 3 (published by the IET - The Institution of Engineering and Technology), which is updated to BS7671 Amendment 2, it says "Prior to these RCD tests, it is essential, for safety reasons, that the EFLI is tested to check the requirements have been met."
@@kaizenanalyst4833 .I think you're confused...
@@roystevenson1375 i've only just picked up some theory books. No practical experience ever. By all means, please set the record straight.
Those RCD,S are rubbish because that RCD would fail and blow the electronics in them I would stick to standard RCD much better and more reliable
Thanks for commenting
Explain Simon? Because you don’t think the manufacturers would have taken this on board? Lol. Behave yourself
HMO left the chat Simon.
I'm thinking that Lucas had a lot to do with creating this lunacy.
And the meter is only £800
£10.00 on e bay 😂😂😂😂😂😂😂
Don’t tell all the idiots how to do a test, otherwise they’ll think they are qualified to do it themselves
Man you guys must have tons of work lol.
🤔
This is excessive.
Would you do the test on both the left and right plug socket or just the one?
You could do the RCD tests at the DB, easier !
So, it's a failure then?!! as it should not exceed 40ms
1 X’s is 300ms
just put in auto, saves you 4 trips
🍾
If anyone is fitting these new rcbos then there absolutely of there heads, there an accident waiting to happen no need for the technology involved, a simple manual reset button is all thats required and has allways been required, customer doesn't ask you for these and a bigger bill and then to replace these after a yr of so so why bother just fit the normal rcbos,amd for the testing........well how absolutely boring can u be ffs who cares to tell people about this your not gonna teach joe public to do an eicr ffs these guys need to get a life if your a spark then get out there and do aome work and earn some money instead of wasting your time trying to teach people online, thats what a college is meant to do 😂
How come you haven’t done at half times?
So your advertising how to. Do you want todo yourself out of work? Shouldn’t this be left to an actual qualified electrician who is legal todo so
What DIY person is going to spend £2000 on this peice of equipment.. this video is clearly for educational purposes for electricians
Yawn….😵
Better doing it at your db pal
Already made that video 👇🏻
