    UK When is an isolator not an isolator?

    Thats why I said the SWA cables are better ON fuses, not THAN fuses. By critical I mean sockets, hot tubs, things like that. If he replaces the RCD with a fuse because the SWA doesn't need it, whatever is on the end of it could be left unprotected. Safer the way it is now IMO.

    UK When is an isolator not an isolator?

    The smaller unit probably hasn't got any over current protection, its more than likely just an 80A RCD as opposed to a RCBO (but maybe not) so the SWA cable isn't really protected. The one on the right hasn't got any RCD protection but has got overcurrent protection in the form of the fuse. I...

    UK Let’s stop pretending the Joint Industry Board (JIB) is fair or impartial

    I kind of agree, who knows what dan has been through though. Personally I've never bothered with all of that JIB stuff, I worked with someone on the same jobs that takes great pleasure in showing me the array of cards he's got in his wallet, gold this and that, the irony is lost on him though...

    3/4 pole rotary isolator on single phase.

    I was reading a thread on a different forum about someone asking how to wire the above, he was going to put the incoming into the top contacts and the outgoing into the bottom contacts leaving the middle pole free. I thought well that sounds fine but it reminded me of how I've seen them wired in...

    SPD - or not

    Got to 2nd fix an apartment this week, been fire damaged. There are about 30 other apartments on the complex and they have all had their consumer unit changed in the last few months by the housing association, they are RCBO boards, 5 circuits or so in each one, however no SPD's have been fitted...

    Napit.. Do you still choose the job, or do they?

    Its that time of year again and what a ball ache it is. We need to provide 3 jobs but don't have a confirmed assesment date until we give them the jobs, this won't work as we mainly do insurance work on damaged houses and by the time the assement date comes round the houses will be occupied by...

    Whole house ventilation / heat recovery system

    I suppose its use could just be for air movement but I'm not sure that works well either, over the last few days its been extremely warm and difficult to sleep due to the temperature, I've also had more showers than normal for the same reason. Now the steam from the shower still needs...

    House rewire-loft wiring & insulation

    I'd ripped the kitchen out at the time so had space to store it. I just rolled it back up the best i could and carried it downstairs, but it was clean and not full of dust and soot like a lot of lofts I go in.

    House rewire-loft wiring & insulation

    To be fair, when I re-did all my own wiring on a fairly modern house when I first moved in I took all the insulation out of the loft and stored it in my kitchen for about a month whilst I did the various things I wanted to do in the loft. Cant see a customer wanting all their insualtion stored...

    Have I wired this solar correctly.

    So it may not pass any solar current back to the grid at all if the RCBO isn't bi-directional then, is my understanding correct? I think when the RCBO is set it would be a solid copper link between the incoming and outgoing copper connections so I can't imagine a bi-directional or none...

    House rewire-loft wiring & insulation

    90% of houses will have had insulation fitted after the wiring was done in the loft, then more insulation on top of it over the years. I know about derating factors etc but in all my time working in the domestic sector I've never come across an overheating lighitng cable in a loft, and that was...

    Whole house ventilation / heat recovery system

    This setup is finally back working again, we managed to get into next door and have a look at theirs, I couldn't get a proper picture but the ducting looked like this Someone else jumped up and got the details of the unit, Nuaire said it was defunct and sent the up to date version of it, the...

    Have I wired this solar correctly.

    I reckon it did need a new inverter probably. All I have done is run a 2.5 up to the loft for the solar firm and put back the meter and isolator that were there before, there is another meter in the loft next to the inverter as well (along with the DNO meter of course in the cupboard outside...

    Isolator instead of red cut out link

    Why is there a need for anything, I've seen many setups where the tails from the bemco go straight into the meter.

    Have I wired this solar correctly.

    Dont know why it looks wonky in the picture, it looks straight when you look at it, but the cupboard is pretty tight under the stairs

    Have I wired this solar correctly.

    So thats how I wired it then isnt it, seems right to me. All the other circuits are RCBO'S does it still need a bi-directional one? Anyway all that and the labels etc are down to the solar guys as far as I'm concerned, its them that are making the big bucks on this job. I've connected it up so...

    Have I wired this solar correctly.

    This is at the mains unit end after a complete refurb. I've come from the inverter in the loft into the isolator, then into the left side of the meter and then the right side of the meter into the RCBO. The solar guys did all the loft work but had left site before I'd replaced the mains, that...
