I highlighted the condition of an installation several months ago to a client.
In short there is a basement which is very wet and the board holding the cut outs and switch fuses is rotten, and now starting to collapse.There are a TP mains cut out, SP mains cut out, isolators for both and switch...
Hi guys, i have my 2391-52 practical assessment tomorrow and my assessor has said we have to perform the tests in sequence as stated in gn3 - 2.6.4
Few questions i have are:
Once i complete safe isolation procedure and remove cover first up is continuity of protective conductors, surely it's a...
i'm a bit confused with this question, it doesn't state what kind of fault so the question is open to a broad spectrum, i'm aware the first point is speak to relevant people regarding faults but after that it could go so many ways.
am i missing something here? i'm reading through the nvq3...
Failed my 2395 written exam and from wanted help understanding the following questions that came up
State two reasons why it is important that the phase sequence is confirmed throughout the installation?
State two methods to confirm phase sequence with an installation?
Anyone else waiting on results back from a recent 2395 exam?
I done it 2 weeks ago and should find out how I done tomorrow.
I feel I lost a whole chunk of marks on two questions based on:
1) Earth rod resistance testing
2) Phase sequence testing
Naively neglected these topics during revision...
Has anyone come across a phase sequence fault when switching on a voltage optimiser for the first time. The system is a cheap chinese one I think with terrible instructions.
Can a voltage optimiser know if your input wiring is black, grey, brown instead of Br, Bl, Gr? I ask because we don't...
im new here so please be gentle with me...lol
i have just started a new job in a factory, maintenance spark.
a few years ago the company had a PIR carried out and guess what, its my job to sort out all the faults,,,,,,,, happy days... not
my question is
they have been given a code 2 for...
To protect equipment eg motors, generators, against phase-phase fault, one uses a Negative Phase Sequence Relay. Appreciate if anyone can explain the working principle of the relay. Is it similar to normal over-current IDMT relay?
Evening all, Have got the above mentioned multi-function tester, have had it for a year or so but never got round to setting up the bluetooth feature. Is it any good and does it actually save time? Also does anyone know if the software is compatible with the NIC forms?
I'm about to do a rewire on an old lighting circuit. I'll have to remove and replace some wiring but not all, thing is, up till now all the circuits I've worked have followed a nice neat radial pattern, but this one is split into 2 or more sections, ie; the line from the cu is split at a jb to...
ElectriciansForums.net (formerly known as ElectriciansForums.co.uk) was setup in April 2006 to provide free electrical advice to both professional and DIY electricians. Whether seeking advice for auto electrics, trying to find electrical installation condition reports (EICR) form downloads, or whether you're here just to talk to other electricians; we've been a first-choice website for tens of thousands of sparkies for well over a decade.
