    Confused ...IR readings

    This is interesting, I wasn't previously aware of this. There is no explicit mention of it in the OSG, which many trainees/apprentices use as their quick reference/refresher to the testing procedures. Looking into it, I see it is explained in GN3 as being introduced with the 17th Edition...

    Low Generation

    That seems OK to me. Nameplate 190W rating of modules is most likely at standard test conditions, e.g. AM 1.5, 20oC ambient temperature, and 1000W/m2 irradiance. At the time of your visit the measured irradiance was 20% lower and the ambient temperature was probably greater than 20oC. I...

    TNCS High ZE at origin

    Are you measuring the Ze with all earthing and bonding conductors connected to the MET? This could result in your 9 ohm reading through an earth path formed by some other extraneous-conductive-part(s)?

    Phone Line not working but broadband active

    This could also be the result of an external line fault if you find nothing wrong with your extensions. At your master socket check for voltage across 2 & 5, should be roughly -50V DC. If you get no reading or a very low voltage then there is an external fault preventing you getting dial tone...

    Overload protection omission

    Had a quick look in the BYB. The '3m rule' is to do with reg 433.2.2. Something for me to read in a bit more detail and compare against fault protection requirements sometime.

    Pete's Videos What a Dork, yes I know I need a hobby

    His 'jiggery pokery unit' is just a bodgy bunch of socket outlets screwed to some ply board and am I right that using a 3kW water heater as a ballast in case there is a fault on the hedge trimmer is a load of b*****ks!?

    How many ethernet sockets to install?

    Is that with the 4 ports in the living room forming a total of 4 circuits, 2 to each of the bedrooms? If so I guess you've selected a place in the L.R. where you anticipate the Internet service will be located and probably where the television might go. Or is it 8 separate circuits run back to...

    Jeremy Vine BBC radio 2 on part P

    Caught the bits where someone text in to slag off 90% of electricians as incompetent and saying that people should do it all themselves and the bloke who rang in to say his kids decided to make a water slide upstairs and now his pendant below didn't work, as with other posters was left a little...

    Where to start with no experience.. Home Study ? Evening/weekend course ?

    I did my Level 2 last year at a local college. I had no previous hands-on experience and found it a very worthwhile experience. Being taught by a lecturer who has worked as an electrician for years also made it easier to understand the theory units. I was able to take the time out for a couple...

    LED PIR security light with manual/pulse override

    The performance seemed good enough for our install as it was above a back door into a patio/garden area on a housing estate and the distances from which it could be approached from the sides were not very large.

    LED PIR security light with manual/pulse override

    Put up an NVC 10W LED one the other day with built-in PIR and manual override function and settings adjustment on a small remote control. Not sure if the override has the option to be timed though. Had factory fitted three-core flex for permanent feed and the rest is done inside the unit. I...

    Serrated washers on steel conduit

    I'm interested to hear what others think about things like this. We are taught that metal conduit and trunking must be earthed regardless of whether or not it is used as a c.p.c. (as it is an exposed conductive part) and that you should achieve electrical continuity throughout the containment...

    Dash Cams

    Have a RoadHawk one which i've had 18 months or so, it's relatively discrete and produces very good quality video, far better than a dirt cheap one (tried one and returned it within a day). Have a high speed SD memory card in it, if I need to look at the video files I take out the card and...

    Who uses a tool belt?

    I have a cheap Forge Steel/Screwfix one. I don't wear it all the time but it is useful, particularly when working up on the steps.

    Tilers forum mixed with electricians forum

    I still find it a bit annoying, I use RSS feed to see what's happening on here and the ported tiling posts occupy a lot of it and it's not always easy to distinguish them from the post titles.

    2365 Unit 301

    Hi, I suggest trying the exercises on the Swindon Massive website, listed here under 2357 unit 602. You can test your existing knowledge and see what you need to work on. 2357 Index - http://www.swindon-massive.co.uk/electrical/revision/2360pt1/2357_index_page.htm

    Course work help needed! (Assignment)

    Not on the C&G course and do not know this assignment. Something that comes to mind for A could be fault conditions caused by severe rodent damage to cables. Agree heat damage is another good one if buried under thermal insulation - especially if additional has been installed years after the...

    RCD needed With minor works?

    My understanding is that this work does not require notification to the Local Authority Building Control under Part P of the Building Regulations. You get this online and look at the section for 'non-notifiable work'. However I have far too little experience to comment on what your obligations...

    MICC/PYRO. CABLE FAULT. / FUSE NOT BLOWING

    Did some MICC at college recently. I have a CITB book from the late 80's which I used for reference and the process and tools are the same. I suppose with many decades the difference will be imperial sizes moved to metric and perhaps different materials for potting and insulating the bare...
