Did a lighting job a few days ago in a sports hall , changing out dimmable surface mounted light to 600x600 LED panels .
There was a bit of rewireing to allow for standard switching as the old setup was a mains feed round the lights and a 2 core belden from a refractive switch .
Seemed to all...
I have posted this in the Qualifications forum but nobody was answering and I need some info for my retest on 2365 Level 3 fault finding practical (303) before next week.
My question is not on the online test, I have already done this.
I failed this test the first time round as I got caught on...
Hi
I own a Megger BM222 meter with a fault. It works on the 500V range, but there is no output on the 1000V range.
I am trying to figure out what the fault is so I can fix it.
On the 500V range, I can hear the internal relay clicking when the button is pushed.
When I push the button on the...
Hi all,
Customer is buying a Tesla ev and he was thinking of getting a Tesla charger but he said to give him 1 quote without a charger (him buying Tesla charger) and 1 quote with me supplying a charger…
The Tesla charger hasn’t got pen fault detection and I’ll need to fit one. The existing CU...
Reviewing earthing methods and come across this.
Suppose a TT system is installed where the installation earth penetrates the PEN, not completely servering it but enough that it effectively creates a second circuit (see image).
Am I right in thinking that this is effectively undetectable?
The...

Hi, turned on (LG) TV this morning and got a 'Select Item' screen and the volume graphic flashing constantly. The remote works and you can select menu items but it returns to the 'Select Item' menu shortly after.
I looked online and some suggested faulty power or HDMI cables, so I detached...
Bear with me because this is long. So got an intermittent fault on the upstairs lights. Trips the mcb after a few hours, getting a reading of 0.01 mega ohms between live and earth at the board, tested cable going to db from first switch and it’s clear. Tested the cable going from first switch to...
Hi,
I've recently looked at a fault with an intermittently tripping RCD at a property for a landlord I do the odd job for.
Got there and did the basics, IR'd the cables, looked at resistances across the pump, got acceptable results everywhere I looked. Played with the heating, demanded hot...
Was at my parents at the weekend getting their tree down out the attic, and I noticed their inverter was reading 0.0W….
Popped in again this morning to check it was getting power before I thought about cracking it open.
Can anyone explain what everything means compared to what I think they...
Hi
I have only had a quick look at a fault so haven’t gone too far into it.
Lighting mcb tripped out, elderly lady wanted it checked out before it went back on so meggered it, all lights worked but rcd would not trip.
It’s a BG 3+3 split load installed by someone when the heating was done about...

Hi all,
Just been on a kitchen remodel, has used the existing cooker feed due to difficulty of run/budget, but the kitchen fitter has kindly put a couple of rows of shelf brackets directly above the cooker switch and perfectly pinned the N to the CPC. Builders being builders seem to think it's...
I had a bit of a head scratcher today, I think I've got to the bottom of it but thought I would run it past you guys.
0.15MΩ between N and CPC on a ring circuit.
I started breaking down the circuit and when I disconnected one of the sockets the fault cleared. I now got 15MΩ. Nothing obvious...
Hi everyone. I'm not sure how this works but if anyone is able to help point me in the right direction that would be great. I've got a Monarch water softener and the display isn't working. When I turn on the power it shows just a blue screen. When I press the buttons I hear a beeping noise and...
This is a baffling fault I've been fighting with for a couple of weeks now, so I wondered if another set of eyes will help.
I installed an EV Charger a few weeks back, and all went well for a while, then the client called me to say it wasn't charging randomly. Resetting it brought it back to...

Would anyone be able to recommend fault finding books or YouTube videos. I’m just looking to brush up on my knowledge. I currently work in fire and security.
Hi all,
I’m about to complete my portfolio and need some help to get Unit 115 - Fault Finding signed off.
I work in maintenance and we don’t have multi-tester I can use for this module. The assessor brought his when I did Inspection and Testing, but I ran out of time to get one job for 115 as...
Advice required please guys.
Currently doing my electrical apprenticeship and encountered a fault today with my colleague at work which left me abit stumped. Customer had tried to change a light fitting and “just put all the blacks together” apparent that one of these blacks was in fact the...
