Morning guys!
Went to look at a consumer unit change today with a PME supply.
Now, right next to this was an old BS3036 60A fused mem cutout that then sent a pair of 16mm tails to the consumer unit up into the loft, across about 3m and then down the wall in surface trunking down to an old...
With apologies in advance for the newbie question...
I'm using a multimeter to figure out the source of my battery drain, so attempting to measure the leakage current between my battery terminal and its lead. When taking the readings shown below, they are quite steady, but as you can see, on...
Hi guys. Hope everyone is keeping well in this strange time. Completed my am2 on Wednesday and waiting to get my results. Firstly my assessor said I was competent and his words were ‘I’d let you wire my house’ which filled me with confidence. Then when I asked for any more feedback he said I...

Hi
Has anyone considered that every time you do a continutity/earth loop test, on the same circuit you get a different result every time?
I had an end to end test on a ring circuit today and kept pressing the test button. The results jump all over the place.
How credible is any test if the...
A colleague has been asked to undertake 5 yearly periodic inspections and certify. He has passed the 2394 and 2395 practical and online elements however awaiting writen exam results.

Re wire teams required in Glasgow for large contracts under way & more coming up and over X mas.
Top rates paid to you at £225 per head (this can go up for the right squads) for a 3 bed & under, no 4 beds have been done to date but the price will go up.
Feel your current rates don't match your...
Hi all,
I have come across an issue that i know others would have.....
I done an Insulation resistance test on a lighting circuit with no selv or pelv just regular pendants circuit. Now the customer informed me they had a leak from a bathroom a few months ago and when i tested this particular...
I have for years been trying to get my existing split-phase supply upgraded to three phase. The DNO sent me a succession of ridiculous quotes, all around the £25K mark.
No amount of negotiation, or pointing out that the existing transformer - which supplies only three houses - was ancient, had...
Hi,
My new leakage tester arrived so I wanted to try it out, I connected it to the Line and Neutral meter tails and got a total leakage with all circuits on of 8.05 ma, I turned them all off and re-tested individually and found that the first floor ring final was giving the highest leakage of...
Good morning guys.
Two days ago the battery of my car was almost died. So yesterday I tried a jump starting, very simple exercise.
So I connected the + of the charged one to the + of the worn battery and then the - of the charged one to the body of the "discharged car".
I turn on the dashboard...
Just tested a bungalow and fond the power is all supplied by one radial 2.5mm circuit rated at 32A on a fuse not MCB. Was thinking C2, there are only 15 points in the on the circuit and most re not used. will be carrying out a full rewire in a couple of weeks any way. If I reduce the fuse size...
Had an old Fluke for years, which has incidentally been faultless . Company purchased a Megger last year however when doing Internal earth fault loop impedance readings are far higher than expected.
I.e..example
Ze = 0.20ohms
r1 + r2 = 0.15ohms
Zs should be about 0.35ohms however coming...
I sat my ECS test today. I was told by examiner that result would be posted to me in about 2 weeks. Is there any way I can get the result sooner ? Cheers.
Afternoon all..
I have just been testing a ring final circuit and got r1 = 107Ω
It is TNCS, rN is 0.4Ω
I'm sorry I haven't got anymore results for you, I'm nowhere near home at the moment and those are the only 2 results I can remember.
This is on a kitchen ring and the Kitchen is being...
