done a small job today. just a socket & SFCU ( for a light) in customer's shed, on existing feed. feed cable is 2.5mm on a 16A MCB, RCD protected. cable tested OK, installed bits. Zs 2.4Ω. ramp test of RCD, mft reads>51mS. prerssed test button on RCD (which the customer said had never been done...
I have an MI 3125B. When testing for Zs at a socket I touched the test button with my thumb, the tester buzzed and displayed the 'dangerous voltage on PE' symbol. So I de-energized the system to look for the fault. There was no fault and insulation resistance at 500V DC was >999 MOhms.

Hi everyone :)
I have a question which i need a little advice on.
I have a set of speakers for my computer which have touch buttons for the volume. There only seems to be one wire going to each button.
The speakers are placed at the other side of the desk (large desk) so i cant reach them...

I have been out to a faulty immersion and have found that there is current through the thermostat. but no current after the next component between the two white wires. what is this and what does it do? and is it bypassable , repairable without having to change the whole element.
thanks

Hi chaps
Having quite a heated discussion with a colleague about a 4 pole RCD. He originally installed a 30mA RCD which now needs to be changed to a 100mA, however the N is on the opposite side. He seems to think that putting L1 into N of the RCD, L2 into L1, L3 into L2 and Neutral into L3...
Hi All
I have purchased and installed the Saxby Lighting Ikon square medium IP67 13992 Decking Lights, they look really good.
Ideally what id like to do is to have these come on when someone is out in the garden.
It seems that there are plenty of 240v PIR outdoor/external sensors, indoor 12v...
I have just been doing some work on a CU which has BS3871 push button MCBs and all I can see on the things is Wylex SK and 6A, how do I tell the type and the breaking capacity
I have a problem to sort out - it is a TT system with a faulty 80A 10mA RCCB after the meter and before the consumer unit. The board is very old style MCBs with no RCDs present.
The customer called me up because until about 6 weeks ago the front garden lights were causing the RCCB to trip. I...

Hey,
so there have been so many discussions about the Pirate parties in Northern Europe - they mostly say they represent the interests of internet users. E.g. they are for the free use of internet and very popular in Germany at the moment. What do you guys think of them?
Hi all.
just wondering if anybody has any diagrams for stop circuits which are used in school workshops etc. It has been a while since i have wired 1 and feel i need a refresher in this area.
thanks for any help.
Anyone know which makes/brands, if any, have the test button wired between L1 - L2 instead of L1 - N? I'm looking for a four pole RCD to protect a TP circuit without a neutral and still have a functioning test button.
Just had a thanks (very rare, like hens teeth!) and i got to thinking, unless you go back over your posts you never see who thanked you (unlike the "like" button).
Have i just missed where to look or can you not look up who has thanked you?
