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...
Hi, I was changing an old Square D board, RCCB MAIN SWITCH, because it was tripping at 12mA when doing a ramp test.
Installed an rcbo board, and ramp test still trips at 12mA??
Any opinions on this?
I am never quite sure if I am doing too little or too much when someone has a flood and I am called in.
The most recent example is a chap has had fairly major flood damage to ceilings, carpets etc and it has poured through certain ceiling pendants and downlights.
Advice on the net states that...
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...
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
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...
