Ok its getting late and my brain not operating at full whack
Where can i find definitve resistance values for SWA cable, PVC and XLPE using 3core and 1 core as earth so looking for R1 + R2 values.
I have seen this info somewhere before, but cannot put my hand upon it.
thanks in advance.
Advice please. I have a PowerOne Aurora 3.0 inverter for PV panels which was installed in July. On Tuesday (Jan 8th), we came home to find our electricity had tripped. Put things back on and thought no more about it. Checked the inverter in the cellar on Wednesday to find lifeless. Switched both...
Does anyone know some good websites or videos showing you how to do the relevant dead tests on electrical circuits or sites with information about each test.
Would really help me with my revision, thank you.
Just had a call off my electrician (one doing council work)
He did a CU change - on testing he IR tested the lighting circuit (500v DC) and got acceptable readings.
When he energized the circuit - RCD trips. Found a dead short between N and E. Investigating now to locate which run of...
How do I bring my dewalt battery's back to life, has anyone tryed and tested it, someone told to stick 1000v from my megger could this do it? Any suggestions would be great.
when doing an inspection i came accross a radial circuit serving 4 points, the IR between L-N @500V was 0.00 Mohms, on continuity between L-N I got 25 ohms. when I then energised the circuit and clamped the live, no current being drawn. I have yet to take any fronts off as it was just an...

Firstly, please let me explain the fault on the circuit HAS been rectified. This was achieved by splitting the offending circuit (kitchen ring) into two radials and putting each leg on their own 16A mcb on the same RCD.
Attended a property to do some remedial works on the kitchen ring, New...
Right.. i gotta text from a mate at the weekend saying they've tried starting their pool pump up but it won't run, he said it was buzzing but not running. I went to take a look today and it turns out it's the contactor that's buzzing but the motor does nothing at all. All i had on me was a volt...

Hi all,
I have been asked to dead test only some modular bathrooms installed in a building. Each bathroom has a light, towel rail, shaver outlet, and extractor fan.

Hi
I am bit unsure when carrying out dead polarity test on a one way switch and two way switch. Where do the test probes go and on what?
Do we make contact at the switch line and the cpc of a ceiling rose? or do we contact at the line and cpc at ceiling rose?
What happens in two way switch...
Your Duck is Dead
A woman brought a very limp duck into a veterinary surgeon. As she laid her pet on the table, the vet pulled out his stethoscope and listened to the bird's chest.
After a moment or two, the vet shook his head and sadly said, "I'm sorry, your duck, Cuddles, has passed...
