I said it when amendment 2 first came out I will continue to test at a 0.5x 1 x and 5x . Also I was under the impression that The 0.5x and 5x was dropped because some people were returning perfectly good RCDs thinking they were faulty because they failed to trip at 5x ? . The 1x test is all we did back in the eighties , so it seems that the reg have moved backwards . Then not all RCDs will behave in the same way , one might fail the 5x and pass the 1x yet another one might fail the 1x and pass the 5x . So for me do all three test on both sides of the sign wave. So no BS7671 hasn’t got it right Or have I missed something here Great video Gaz as always 👍
You’re KTS1620 has always been compliant . BS 7671 has no impact on what brand or type of testers we use , only that a loop test for loop testing RCD tester and continuity/ insulation tester hence why it doesn’t mention these instruments by brand name or make .
Failed but strange it failed to trip on x1 where tester injects 30mA but ramp test showed it was tripping at 27mA, it possibly would have at maybe 500 ms but thats a fail, I would try another tester to confirm one way or another. As far as using AC x1 on all types of RCD / RCBO whatever type they should all trip on ac settings. Enjoy your videos been a subscriber for some time eFIXX channel too, keep asking questions of the industry.👍
Under amendment 2 that RCD has failed. On another note, it seems daft testing on AC for all RCD types. As, for instance, a type A RCD will respond to pulsed DC values of root2 x the AC values (30mA). So a 30mA will take 42.42mA at x1. Hence the slower times we now tend to record, sometimes up in the 150ms range it’s a lot slower now than what we was used to🤔
I m8ght be wrong but i understand that AC setting is right for all rcds. If you set it to type A . You are only testing functionality of its dc side of things. Which is above the capability of a type Ac. So if you set to type F again you will be only testing what is above the standards of the pervoius 2. So i to put it plainly each extra symbol on the rcd has. Its that part only you are testing.
No loads connected during the test. We are now only required as a minimum to test any type of RCD as if it is an AC RCD and at 1 time i delta n. Just asking the question in the video has BS7671 got it correct to test RCDs this way… thoughts…
I failed mt am2 becaus i did not test the rcd to industry standard. After working oyt what went wrong for a simple test the conclusion was i did not do the first no trip half test as per GN3. After the half test then tje times ine at o and 180
Did you ZS each circuit prior to testing their respective RCDs? As during a ZS test you send 15mA down it, just as would have while testing at 1/2 times... Could have been worth the argument. 😅
Sadly now all of team GSH are working away from FE colleges so you just have the 700+ videos and 2 new ones a week Jerry. Massive thanks for watching and the comment 👍🏻

I believe this regulation just made my KTS 1620 18th edition compliant.
😀

Do you get the same outcome using the 3 lead test ?

Thanks for the support across both channels 👍🏻
GN3 states a 1/2 test is done first then a 1x test not a 1x test only
As far as I'm aware, type A, B, AC, and F RCD's all should detect on AC settings..
👍🏻
Great work guys
Thanks 🦾

Love your thoughts Daddy B 🦾
It is failed or pass? As it failed on 1x so I beilieve it is failed.Nice vid Thanks
Failed 👍🏻
Press the test button several times before testing, I find Hager RCDs stick.

Am I missing something here ? It didn't trip at 1 x i.e. 30mA, so isn't it faulty ? Unless there is DC saturating the core ???

How can I get the training from you guys?

@@GSHElectrical Sad to hear that, but all the best for your work and please keep up the great videos posting, appreciate it very much!
Literally had this happen to me last week.
What not passing on times 1..?
@@GSHElectrical Yes failing 1x, but it passed the 5x test no problem.
Type Ac rcd tested at Ac setting so failed ?
Failed at 1 times. All RCDs are tested as AC under Amendment 2 of the 18th 👍🏻
Simple answer. No .
If you had tested again on 1x after 5x it would have passed.
It still didn’t work at 1 times 👍🏻
No
As always my opinion doesn’t mean anything. 😂
