Hi all, when completing a minor works there are two tests that i am unsure the best way to go about, example extension of circuit and new lighting point installed. Fed from industrial 3P board unable to isolate due to plant running. Do not wish to open live board even just for testing purposes...
After fixing a few CPC related issues on a ring final I got the following results
L-L = 0.47
N-N = 0.47
CPC-CPC = 0.69
R1+R2 Tested at 0.31
R1+Rn Tested at 0.25
All looks good, until that is I realised that the CPC-CPC is actually not quite right. It should be 0.78 (0.47 x 1.67 for a 2.5/1.5...
So I have a outlet protected by a gfci breaker, and if you use the plug test the gfci doesn't trigger . I replaced the gfci breaker and the outlet still fails the test. The outlet seems to work otherwise.
When i plug in the tester it shows all green, though during the gfci test it shows hot...
Thanks to mister @marconi , I received his chip AT28C16 gift from England !
I will start to make the 5x7 led matrix project that you did.
I will make it alone as much as I can (as usual). And I will ask you for clarifications on the way.
I had just installed a heat alarm on the downstairs lighting circuit during a kitchen rewire.
The new kitchen ring / cooker circuit I tested IR for L-N and N-E at 500v, fine, but the DS lighting circuit consisted solely of 21 LED downlights, in various rooms and the alarm. All of which say do...
I have a 115vac line that tests with proper voltage and will power a low watt bulb but will not run a drill etc...
Line from main panel to barn is 10-3 copper on a 30amp breaker.
Sub panel has two 20amp breakers one for lights and one for plugs.
Wire was run 30 years ago and ran a vacuum...
Hello all, I am a QA manager located in the Netherlands and we conduct on site product inspections using a third party company in China. Some of our products use rechargeable batteries. I am looking to identify what kinds of tests our third party inspection company in china could perform on...
I’m new to the forum so first of all a quick hello ? I have my AM2 in the near future & got a query regarding the schedule of test results, namely the cable reference method and cable type. I know reference methods can be found in BS7671 (APP 4). Where there is more than one method for a...
As title, select the correct settings L-L L-E on left and As on right, am unable to change mode (2Lo 2Hi etc.
Screen comes up with <50v but does nothing else.
Any ideas? Runs continuity and IR fine, not tried RCD
I’m a fully qualified electrician and am going to be moving over to London and am not sure what cards and tests I need to take to be able to work on site I know I need and ECS card but have been told I need more than that
How come the sequence of tests in guidance note 3 is that the Zs test comes before the PFC test?
Isn't it normal to do PFC test before the Zs test? Because then you can do your PFC test, put the board cover on and energize the board without coming back to do the PFC test.

Folks,
A bit baffled (not difficult) ... added a light switch in a rental this week (empty property so no social distancing issues) and checked the RCD before I signed off. It was a Wylex 80a 30mA and it failed all tests (inc. ramp) so I like-for-like replaced it. The new one also failed all...
Anyone an idea why an RCBO measures >40ms on a 5x test on the second half of the sine wave but all other tests are within requirements? Sorry, it's not a single RCBO, there's 2 RCBOs in this board and both have similar results leading me to think not a faulty RCBO but an issue further upstream...
I have a brand new MK 63amp RCD that fails Ix5 test everything else tests fine on the board, I tested with all circuits off everything unplugged so swapped it for another thinking must have a faulty one but the same result, it will trip at 50ms and ramp tested at 33ma, ze=0.18 what could be...
