Hello everyone. I installed a new instruments panel with a tachometer for my old car (Fiat Uno) the board is for a Fiat Palio but the connections are the same and the panel fits perfectly. The only problem is the tachometer, it displays 4000 rpm when the car is turned on but idle, and goes all...
Hello,
has anyone noticed in the new GN3 that any reading below 20 Mohms now has to be investigated or is this a printing mistake as it used to be 2Mohms?
Thank you

I want to talk about the context to this first, I'm in my first year at college studying level 2 electrical installation and for Christmas my family got me a toolkit which had some tools , multimeter and a soldering iron. They didn't really know much about things like that and they wanted it to...
Hi I’m looking for work as a mate or labourer in Reading or surrounding area ... I started my 2365 at college in September and all going well so far .. im just itching to get on with some graft and gain more work based experience .. thanks in advance
Hello , ive just got off the phone to niceic regarding a pfc reading of 8ka.
Ze reading of 30.2 ohms on a tt installation and pfc of 8ka.
MCBs rated at 6ka so obviously I was not happy with the higher test result. Niceic said all was ok due to 230 divided by 30.2 = fault current of 7.6A and...
Testing a ring earlier and found 0.8M ohm at 250v between (L&N) - E.
This wouldnt be a neon causing this would it as im testing between L N (joined) to E ? I have not yet tested between the three individually.
This low reading is making me hope somethings still connected, there is a digital...

Good evening all,
I am seeking any work opportunity to help me make a career change to become a fully qualified electrician. To begin achieving this goal, I will be starting a Level 2 electrical installation course in 2 weeks time at Langley College. I have my own transport, am ready to start...
Hello I'm getting fluctuating resistants readings when using a megger mft 1710 meter, Does anyone know whats causing this / how to mend it. Ive tried taking it apart to have a look inside but can't even take it apart does anyone know how too (ps its not the same as the older testers)
Hi there,
Fully qualified but only 2/3 experienced taking on some fairly difficult jobs working alone. Learning very fast but I could really do with some local guys/gals to team up with from time-to-time.
Ideal person would be on top of their theory & regs with a good standard of workmanship...
This is one of those slightly embarrassing questions that I feel I should know the answer to. I can feel the answer lurking under my skin but it's just not surfacing and needs a push!
Pre-work visit for a CU change. There was 65K Ω resistance between N-E on the continuity setting, however when...
Hi Guys and Gals, currently I am finishing off my NVQ & i'm being asked the question on One file "Check the safety of electrical systems prior to the commencement of inspection, testing and commissioning".... Is this just fancy wording to say check Ze before you do anything else?
Any advice...
Hi All,
I am hoping to that someone might be able to point me in the direction of a suitable resource that will help me interpret the details of site electrical plan that will allow me to get the necessary details that I can use for cable calculations.
I came across this issue when I was...
hi guys just wired up a new ring main for a house, confused on the test results though, firstly all other ring mains in the house that are new are okay and have came out as expected, tester has just been calibrated and batterys are okay and the ring main is a true ring... am using a metrel...
Hi One and All.
Fault finding today. Narrowed it down to one leg of RFC between N&CPC.
What puzzled me was the fluctuation in the IR test. Normally I find the reading stabilises after a short period (5-20 seconds). Today the reading was constantly jumping between 20Mohms with an occasional...
Hi guys, New to testing but been doing installations for about 5 years now. I've come across a problem where the ring I'm testing has no R2 reading, I've split the ring and done a r1+r2 test to find out which leg it's on. Problem is I don't know how the ring was wired. Is there an easy and...
A neighbours underfloor bathroom heating mat stopped working a while back, she asked me to look at it today. Turns out when it was installed the joiner had accidentally burst the cable for it. It's a small thin blue cable that heats up that has two conductors & an earth. Someone has done a...
Hi there
Been stuck on this for a while. What is the maximum r1+r2 reading possible on a lighting circuit in a domestic property. With a type b 6amp breaker.
Also if you guys could tell me about r1+r2 and rn Maximum readings for ring final.
Thanks
