    Client here! Thanks for a good job, chaps, and sorry I got stuck in traffic and didn't get to meet you. Fun to see my place on TH-cam! I can clear up one of the mysteries - the second load on the cooker switch is the spark for the hob; if you slide out the middle drawer underneath you can just about see the unswitched socket with it on. The metal lights in kitchen + bathrooms were there when I moved in (2014) but the lounge and the hallway (with quickwire connectors!) were all me. Sorry I scrawled hall sockets on the wrong side of the paperwork. Clearly I need to tighten up my connections a lot more when spreading USB sockets round the place, but as you saw, I've got loads of them so unlikely to do any more. Oh, and there is a fifth accessible socket in the kitchen [EDIT] which I can see from the report you must have found off-camera.

    The second oven cable will go up and over to a connection plate behind the housing, the other will drop down to the hob. The norm for new build. Even if it is 13 years old.

    On most big new build sites now NHBC would fail the pre plaster inspection if the tails or 16mm twin didn't have "additional protection". This has been the case for at least the last 10 years. But I agree better in SWA but on the new builds it comes down to price and time and it's much quicker to terminate 16mm twin!

    That smoke alarm must be a US manufacturer. we are required to have no junctions in the wall that are not accessible so if there’s a junction It has to come out to a box with a blank plate unless you’re going to use it for something. All lighting circuits will have a back box as well so there’s usually not enough room still to have wire junctions for lights, by the time you get the fixture up there and in the mounting bracket what looked like plenty of room goes down to nothing. So all our lighting fixtures have a few inches of wires hanging off the back that you will attach in the box and then everything is self-contained when the fixture is up. We also require a CPC / ground in all boxes but as we know those don’t always get continued continuity. I constantly find it interesting when you pull up floors and you find all those junctions as over, here that’s been classed as against code for a good while; it aids in troubleshooting as you know if there’s a fault between the two boxes it’s either going somewhere or it’s been nicked.
    I make these US comments because through the videos and comments on TH-cam I became fascinated with UK wiring and other cultures electric. It’s interesting how we’ve adapted are codes and then started taking things from other peoples codes.

      I suspect that’s a US manufacture, we require all fixtures to have back boxes including smoke alarms. That is a separate item purchased during first fix usually, so when you go to put the smoke alarms up there’s already an enclosure for them. But global market place and all.... they probably just re-purposed the design and change the electronics a little one slapped them in the UK label box.

    • @tomorichard
      @tomorichard 4 ปีที่แล้ว +1

      You could if you wanted but a 100ma S type would not offer the protection “additional” that Chris is concerned about. Only a rcd with a rating of 30ma can do that, fitting one at the origin would arguably make more problems than exist already.
      I think a good way of thinking about it is anything other that a 30ma is intended to offer fault protection where a max ZS can not be achieved thus a rcd is required to clear a earth fault because a over current protective device cannot do so.

      That model is just a transformer, so 8V AC output. As it's not earth referenced, the blue isn't a "neutral" so should be sleeved black if you're being really pedantic. For DC it would be brown and grey to current standards.

    Why do you switch the neutral

    • @imark7777777
      @imark7777777 4 ปีที่แล้ว

      The neutral is considered a semi hot so there is generally a main isolator that breaks both. I suspect this goes back to the standards before they had a color-coded neutral. Where it would’ve been very easy to swap it and not have an issue until somebody went to work on it and thought it was off.

    I don't really see the problem with feeding two ring mains from one RCD. What exactly are you hoping will still be powered on while you're investigating the fault? Much the same applies to lighting. Why would I want the lights to remain on upstairs if the RCD has tripped while I'm downstairs? There may be a tiny, tiny, nanoscopic advantage to having an RCD or RCBO on each circuit but it hardly justifies the enormous cost.

      Having lived in this flat for six years, the lights all on one breaker doesn't bother me (unless I'm putting a new one up and would prefer some light from an adjacent room!). Losing all the sockets including five minutes for the internet to come back after an RCD trip is a more common annoyance though.
