    Wall insulation

    Reference method 102 is not a perfect match but the closest to the situation, if this this correct then given that a 32A must have a capacity of at least 20A per leg this would comply as Ref method 102 gives 21A for 2.5mm csa T&E.

    Wall insulation

    Its 0.88 for 50mm and 0.78 for 100mm 523.9 specifies that if the cable totally surrounded by thermally insulating material over a length of 0.5m or more then a rating factor of 0.5 is used. My problem with this is that the cable is not totally surrounded by thermal insulation so this doesn't...

    Wall insulation

    Just first fixed a house where I was initially told that the external walls were going to be battened then boarded, I used metal capping over the 2.5mm T&E ring final circuits on the external walls and chased the internal ones into the wall with 20mm oval conduit. I have now been told that the...

    Which M Class dust extractor

    Thank you for the reply, I was all set to buy the Bosch Dust extractor so I called the local supplier and explained what I would use it for (core drilling and Wall chasing) and he said that it is no use for that and it doesnt cope very well with fine brick and concrete dust, he said it rips up...

    Which M Class dust extractor

    Have you ever used the Bosch machine? They are both around the same price which makes the decision difficult as they both look good machines. The Metabo seems to only connect to Metabo tools? maybe is has adaptors?

    Which M Class dust extractor

    Hi, I after opinions on which M Class dust extractor is better for chasing and coreing holes. I have narrowed it down to either the Bosch GAS35 AFC or the Metabo ASR35. Any one used them both?

    2 way LED dimmer problem

    Yes the lamps are dimmable, I wish it was that simple, the customer is insisting on 2 x dimmers. I assumed that because it clearly states its a two way dimmer that it was a new type of dimmer rather than master/slave which is not possible without wiring a neutral into the switch. Very misleading

    Part P assessment question

    If the outbuilding had extraneous conductive parts then I would have put a rod in. The question had no relevance to the job he was assessing this time as it had a TT earthing arrangement and no specific details were given in the question, just how would I do it with PME Earthing

    It says that I need to prove that I now know the correct procedure. How exactly can I do that?

    Stroma, I am at the moment but I just wanted to check my facts as the assessor was insisting that I was wrong and listed it as a non-conformity.
