    I work in the nuclear industry, we can't use an mcb to isolate. The air gap isn't big enough, or some shit like that. It's a massive pain in the hoop for everyone having to isolate further back.

    What happens in the absence of an isolation switch, does the DNO have to fit one?

    • @TheChriss45
      @TheChriss45 3 роки тому +2

      I've got the same problem but the DNO wants to bend me over for £231.42 to put an isolator in. My consumer unit is ancient, needs replacing and electricians round here won't work on it because there is no way to stop power going to the fuse box, without removing the main fuse - and the DNO has already fined electricians for doing that without their permission. So, I am stuck till the DNO comes out.
      What amazes me is the complete absence of a video on how to work on a fuse box that doesn't have an isolator, surely if there is a switch it is a no brainer for electricians (the challenge is what to do when there isn't one)!

    • @JohnSmith-ws7fq
      @JohnSmith-ws7fq 3 роки тому +1

      ​@@TheChriss45 Yes, it's a problem. The proper way to do it without a switch is to book the DNO to pull the fuse, organise the electrician to do the work at the same time and then book the DNO to replace and reseal the fuse. Can be difficult to organise everyone to turn up at the right time, and if it goes wrong you can be without power for days.
      Many electricians will pull the fuse, but it's a legal grey area, and if they've been fined by your operator, probably not keen on doing that. To reseal perfectly you need MOCAPA-compliant pliers and tags, with dies in the pliers that match the coding on your existing tag.

    • @vinm300
      @vinm300 3 роки тому +2

      In most cases it isn't there.
      What you have to do is remove the fuse from the mains supply.
      Put the fuse in your pocket and keep it there until all work is completed. (so nobody is tempted to return it).

    • @dvrn86
      @dvrn86 3 роки тому

      There never used to be a main switch or RCD between the meter and consumer unit. You'd have to contact your utility provider to remove the fuse if yiu wanted to keep everything above board unless it's an emergency.

  • @roora111
    @roora111 3 роки тому +2

    Hello. I have just started learning and got question. Would you prove safe isolation on load or supply side of main switch. Or maybe on load or supply side of isolating circuit? What would be the best practice?

    • @GSHElectrical
      @GSHElectrical  3 роки тому

      Depends where the device for isolation is positioned. If it’s the remote 100amp switch then it’s the incoming side of the DP switch in the consumer unit. If it the DP switch in the consumer unit then it’s the outgoing side (load). Thanks for commenting and watching. Gaz 👍.

    If we have to prove our voltage indicator is working, we then go through the safe isolation we then have to prove that the voltage indicator is working,? Why? This sogests to that voltage indicators are not as good as we might think and that they are not reliable? So why bother buying and using one . Just a thought.

    • @GSHElectrical
      @GSHElectrical  6 років тому +2

      Hi. The switch can be used in an emergency and switch off the consumer unit on full load. However if you don’t have to in this case in my video why would the electrician want to break a load of up to 100 amps and the arc this would create when you don’t have to. Hope this makes sense I am shopping with the wife lol.

  • @justindean70
    @justindean70 6 років тому

    Why don't you use a plug in socket tester that has an audio function?? Best practice in this case would be to use your senses when performing safe isolation, in this case hearing as well as sight!
    Note - It's best practice to 'Un-load' a consumer unit prior to switching off the supply to the installation and perform safe isolation. This is because many isolation devices are not designed to switch 'On-load', they are only designed to switch 'Off-load' for mechanical maintenance.

    • @GSHElectrical
      @GSHElectrical  6 років тому

      Hi.
      5.1 Isolation
      5.1.1 Requirement
      Means of isolation should be provided:
      (a) a main linked switch or circuit-breaker should be provided as means of isolation and of interrupting the supply on load. For a single-phase household and similar supplies that may be operated by an unskilled person.
      So I understand it’s not a good idea to isolate the main switch on full load but in cases of emergency or by unskilled person this may be the case.
      Thanks again 🙌
