    30mm channeling chisel?

    I've just had to return an Armeg 30mm channeling chisel because it snapped after 5 minutes use. The last one I had didn't fair well either, and at £40 + I'd expect them to last! Does anyone know of any other manufacturer of these, don't really want another Armeg because they are not the quality...

    18th edition exam question..

    I passed the exam today, only got 85% so got a handful of questions wrong. I have to admit, there were a few questions which evaded my knowledge and couldn't even find the answer in the BBB! Overall I'm happy though, considering I only booked the exam last week and purchased the BBB less than a...

    18th edition exam question..

    I chose 5 seconds, but the 'correct' answer is 0.4ms apparently...

    18th edition exam question..

    Another question I'd like to take issue with! Regulation 411.3.2.3 clearly states a maximum of 5 seconds. The question clearly asks for the 'maximum' What am I missing?

    18th edition exam question..

    I'd think the same. But I still can't work out what a 'single pole switching device' (switching neutral only) for control of lighting circuits actually is?

    18th edition exam question..

    From the BBB: "A residual current operated switching device designed to perform the functions of protection against overload and/or short circuit" So it doesn't protect against earth fault currents??

    18th edition exam question..

    I think it's a genuine exam question, one of perhaps a few which the 'experts' have wrong. I can remember a similar situation with the 17th exam, where I stated the obvious answer but it was 'wrong' apparently. Even the course tutor agreed. However, this time I've skipped the course and just...

    18th edition exam question..

    Booked in for my 18th edition exam, so I've been doing some mock exams online. Can anyone explain this one? There's me thinking an RCBO protects against over-current and earth fault current?

    AC isolation switch?

    I've done it before, where space was limited, and it all got signed off ok. But, I've never seen any other install done this way....

    AC isolation switch?

    Instead of using the standard rotary isolator for the inverter, is it acceptable to use a standard 100A switch within the consumer unit? It's DP, can be locked off, and will obviously be clearly labeled :-) Anything wrong with this method?

    lenghening pv cables?

    Thanks, I think the crimp connection would be reliable enough, I just wasn't sure if there was any specific rule against this method of joining, given the thickness of the insulation on pv dc cables ...

    lenghening pv cables?

    Due to a change of inverter location I need to lengthen some 4mm dc cables. These are run in plastic flexi conduit. No space for adding mc4 connectors and a junction box or dc switch would be difficult. Is it acceptable to crimp a butt joint and double heat-wrap over the joints? Each one will be...

    PV roof tile fixing question.

    Yes I've tried every angle. The problem is they've fixed the battens with stupidly large galvanised nails ;-(

    PV roof tile fixing question.

    The nails are under the tiles James, that's why a slate hook is used to try and pull them out.

    PV roof tile fixing question.
