    New 20A DP Lightswitch

    You are not understanding the meaning of CPC. In layman's terms it is the earth connection and you don't have one connected to the metal face plate. Just copying the layout of connections from one manufactures switch to another is dangerous, you need to understand terminology. If you did that...

    Compex Question Exe joint box gland

    I'm not well up on the detailed requirements of exe but as a minimum I would suggest to look at the installation instructions of the junction box. If the MI states that appropriately certified glancing is required to maintain the protection concept then there is only one choice. Regards Martin.

    Cable in Plastic trunking

    Absolutely agree with the comment regarding poor planning. Putting that aside, if you just offer what others are doing without really considering the clients aesthetics after completion then your hardly showing yourself to be a step ahead of the competition. Meet the clients needs and they will...

    canon 40d

    Image stabilisation on canon lens is with a designation of 'IS' be it EF or EF-S. Canon have two forms of image sensor size, either full frame (24mm film equivilant) or crop sensor. You can fit EF and EF-S lenses on crop size bodies but only EF lenses on the full frame bodies. The 40D , 50D...

    canon 40d

    40D is a great camera in my eye's. I doubt you would be disappointed, however if you could stretch to a 50D then you would get the ability to have fine tune adjustment on your lenses which is something the 40D lacks. Regarding image stabilisation then this is only via in lens with canon. Any...

    testing problems

    The serial number of the tester stays the same as it is the unique manufactures device number. A calibration cert for it must contain that serial number to identify that unique device. However the cal cert also has it's own traceable reference number. Therefore when it gets a new cert after a...

    Electric Underfloor Heating

    1 test mat out of box. Check resistance and insulation readings against data sent with mat. 2. After laying mat check both readings again. 3. Cover mat with slc and check third time. Then tiler can do his job. Record all readings at each test. Mat instructions will probably tell you this...

    Pliers with built in LED, are they any good?

    Might be tested to 5000v but if exposed metal parts are easily touched then I doubt any test body would certify them as safe work equipment........

    Testing gas pipework for extraneous conductive parts

    Flammable or inert gases and is the area subject to any ATEX hazardous area zone classification would be first thing I would check before flashing around at 500v.

    Storage heaters

    Agree with this post, I can only think that someone has got confused between storage and instantaneous systems because it makes no sense otherwise !! Unless some numbnut thinks they store electricity and not heat ?

    gestapo avatar why is it allowed

    Being a relatively new member (just under 12 months) I was surprised also by the choice of aviator chosen by that member. However the content of message posts that I have seen would not be offensive in my eyes and I think that is what is important. Some themselves may question the content of...

    How to increase Kva

    Yeah I'm wondering what is being cooked up in Cheltenham these days???. Who specified and supplied the hobs in the first place and did they check the available supply to feed them as part of the contract ?? Also if your running costs are 80-90K per year on generator then get back to DNO and...

    Internal or external DB?

    This can only really be determined by the positioning of the installation. If you are happy that the enclosure could be subjected to anything other than vertical drips under normal conditions then you are correct to raise it. However if your concern is that it would be under abnormal conditions...

    SWA fault.

    Well it's guaranteed it was continuous when you laid it, have a look at some videos of cable production and you will understand how it would be impossible for it to come out of manufacture like that.

    SWA fault.

    100% not a manufacturing fault with such clean separation and lack of longitudinal distortion in the armouring and cores. Either malicious damage by persons unknown or something heavy and metallic dropped or unloaded on top of it being that it might not have been visible being hidden by the hedge.
