    Always a good idea to keep an eye out for asbestos on the older boards. Have come accross is being used as an insulating materal between the board chassis and trunking.

    Hi
    I am so happy you started your own channel
    As we don’t have to see Jordan lol
    You have very deep knowledge and you speak better then him
    Your knowledge is very high and deep
    Given your background being doing inspection and testing for years
    Hopefully I love to see more 3 phase boards
    3 phase distribution and their connections on the board
    Also testing 3 phase boards and understanding RCD ARRAIGNMENT and their various types
    Disconnection time and rating of them
    Well
    Thank you so much
    ❤❤❤❤❤❤

    At southampton uni in the late 80s, we had hundreds of the FE stablok boards, never saw ONE connection go bad.
    the same design of board was used in the US under the federal pacific electric brand, they were made to a really stupid US standard that didn't require a magnetic disconnect, and got a really bad name, but the busbar connections never failed, to my knowledge. Similarly i've never seen a starbreaker go bad
    When i was a YTS lad at aforementioned uni, Merlin Gerin was the new hot stuff, so you're right about dating them

    The correct orientation of the breakers on these boards is with the coloured band nearest the centre i.e. the switch lever is towards the centre for ON. The C45N breakers normally leave a bit of busbar on show, that's just how they were. CGD (Before they had anything to do with Lewden) made some copies that were a good fit and had the same issue. The C60 breakers came out with the later Isobar boards which had the slide switches to isolate the individual MCB ways. The later Schneider breakers would fit better if turned around the correct orientation.

      Also, it's normal for three phase boards to have the isolator only switch the phases unless it's on a TT system where you'd fit a four pole isolator. I believe the reason was to avoid the risk of a failure mode whereby the neutral got switched off but the phases didn't. Neutral loss is a bad thing causing single phase appliances to blow up if the load isn't perfectly balanced.

    The open closed problem is real as they haven't removed the stickers saying what way around open and closed are at the bottom! Had a customer really confused by this and said a breaker was on when it was off, I went out to look at why a potwash wasn't working and it was just a tripped breaker caused by a single phase power cut.

    • @JasperJanssen
      @JasperJanssen Місяць тому +1

      They’ve just installed them backwards (the new ones). There’s no reason for them to be in the board backwards since they’re just comb rails in regular cage terminals, same as on the outboard side. As far as I can see from this video.
      There’s no safety issues with that *apart* from the switches going the wrong way, but… should still be fixed since it’s easy.

    • @John_Faultless
      @John_Faultless  Місяць тому +2

      @JasperJanssen so I had a closer look and the 3871 one's have the din rail release on the opposite end to the 60898 one's. So if they put them in the correct way it would be near impossible to release the mcb from the din rail. So I can only assume that was the reason for fitting them the opposite way 🙃 makes a headache to work on though!

    The Federal fuseboard was called stablok as the circuit breakers literally pushed into a slot & locked onto the busbar

    Old federal electric - I always remember as an apprentice the guy I was working with told me to press the yellow test buttons on the RCBOs I pressed one and the breaker exploded and took out a 80A HRC in a switch fuse. Mind you that being said I had the same more recently with a MEM 3. In my opinion the MEM2 is the best 3p board ever made. Shame they have gone the way they have.

    No flash guard over the neutral bar on older TPNs there was of course no reg or reason to fit one when these were manufactured some places wouldn't even allow you to take the front cover off without isolating the board first

    One of the main reasons things got "safer" - and more standardised - was that industry went from employing it's own technicians to using external contractors...
    For a long time, most industrial sites had their own plumbers/mechanics/sparks etc. who trained their own apprentices - so they learned what to do and NOT to do SPECIFICALLY for the stuff they'd likely spend their entire life working-on - they inherited systems and developed them personally - 'safety' came from familiarity, not from safety devices and stickers
    The move away from 'in house' technical staff created a need to train people to work on a MUCH wider range of systems and setups and so there became a need to standardize - as much to keep costs low, you don't want someone spending hours just figuring things out (yes, money ahead of safety!!)
    Always worth remembering that early electrical installations were entirely UNINSULATED - they literally ran bare copper into light fittings in people's houses - we've come a long way...

      One of the older Merlin breakers looks to be the wrong way around too. They don't fit well the wrong way round due to position of the terminals being different at the top and bottom.
