Perhaps I should make a big warning sign saying 'Do not lick!' g The main concern with lead would be its proper disposal, which brings up another EU Directive you need to take into consideration: Directive 2012/19/EU Waste Electrical and Electronic Equipment. That covers just about anything that is fitted with a plug or uses a battery. Probably the bigger hazard is dropping the thing on your foot - it weight about 30kg! In which case, the packaging should show this, along with a warning that it is a two person lift. I'm ahead of you on that one - all suitably labelled with appropriate warnings (about weight & lifting, rather than licking the lead g) Also has a page of 'installation instructions'.... |

I can go to Asda tonight and buy a mains lamp that in all honesty look far less safe than those in the photo. to avoid the risk of expensive legal proceedings The wall wart may be a good idea but are you aware that the light still needs PAT testing if testing is required? AB If the light were powered from a SELV wallwart, only the wallawart would need PAT testing - at times when a PAT test is warranted that is. Which it isn't anyway. But with an external wallwart the safety requirements for the ELV luminaire become lower & easier to achieve. For arguments sake, you remove the mains lamp from the box and insert one lamp and PSU. How do you gain? I'm not recommending it, but you gain by the luminaire being exempt from the rules & regulations that apply to mains appliances. It's why wallwarts are so popular. If the client demands a PAT test on the lamp, it's unlikely that he'll allow the new version to go through also. quite the opposite, wallwarts are trivial to pat test. A wallwart powered luminaire is exempt from PAT testing as it's not a mains electrical device. It would also be exempt from the need to be class I or II, for strain relief & so on. A test is a test full stop. You plug a device into the mains, it's a portable appliance. To argue that testing is somehow easier or less stringent by adding a PSU is ridiculous. AB Then you need to brush up on your PAT testing knowledge. Laptops powered by a brick are PAT exempt, only the PSU needs testing. And I can't see any way in which exempting the 19v laptop from PAT testing would be ridiculous. On the contrary it would be a bit ridiculous to PAT test it, as it's never connected to the mains. NT Let me make it simple for you. A test is a test full stop. You plug a device into the mains, it's a portable appliance. There we are, I got rid of the confusing bits. Is there anythin else you dont understand? AB yes, why I bother replying to you. |

No! Totally different scenario, apparrantly the problems with painkillers in the US are based on what started as a genuine treatment for pain relief. One would be tempted to think that the cause of the problem was private medical practice and a failiure to provideaffordable joint surgery, but some of the deaths have occurred to people that One would think were well able to afford a few new joints. Anyway, I have little doubt that most of the doctors involved are acting in what they see as the best interests of their patients. God help the American people if that isn't the general case, the poor dears have a very big blonde millstone around their necks already :-) And then there's alcohol... A tool, like the odd spanner or screwdriver in the toolbox. Some get great pleasure from it and use it as a way to release their creativity, careful use of said tool can lead to more effective social interaction and can help build relationships. Sadly there are a few who's use of alcohol and also spanners and screwdrivers incidentally, will lead to misery, financial difficulties and a life that is full of incoherent ramblings about their great "successes" and of course the propensity for constantly telling others how to do things.

You like a number of others in this NG, dip in giving out choice advice on the solution to problems you do not understand or do nor care enough about to give a few minutes of time assimilating the information. In service inspection and testing is precisely what the title say's. It wouldn't be simpler to invest in a copy. Impressive as the document is, it isn't simpler to invest in a copy of something that does not apply to an appliance that not only has never seen service, but it hasn't even arrived at the place of use. Perthaps an outline of harmonic rejection techniques might be woth investigating, I'm sure a procedure for testing for third harmonics could be found also. AB |

AB I can't justify it with chapter & verse, but the day something one has PAT tested catches fire the next week, HSE or someone might well come looking for your qualification(s) and evidence of (public liability??) insurance (which dependiing on the size of the fire, you might need to claim on (but perhaps only if you were held to be negligent?) When I say "you", no critiscism of you in particular is expressed or implied, I am sure you know what you are doing with electricery. Such concerns are one reason I will be having my CU changes done professionally. I could probably hire some test equipment and follow the guides in the WiKi, but I still don't have the bits of paper, membership of prefessional bodies, or insurance. |

They would have to prove the item was faulty *at the time of the test* which might prove tricky if destroyed by fire. -- *It is wrong to ever split an infinitive * Dave Plowman London SW To e-mail, change noise into sound. |

It's just the City & Guilds requirement that is false. No formal qualifications are needed. To be honest, when I did the course there were a group from I think, the council all doing the classes with me in between their the jolly japes. I would have more confidence in an enthusiastic amateur! Don't get me wrong it's an excellent course, but at the end of the day it isn't exactly a demanding task to train someone to measure conductivity. I would without a shadow of a doubt recommend it to anyone involved with the practice incidentally, a lot of people engaged in testing freely advertise that they don't know what they are doing. As far as your CU changes go, you are totally correct. In my own personal experience no matter what the source of reference used and how thourough One's approach, the first job or maybe ten jobs, provide the experience to enable the next one to be done properly :-( AB |

AB I can't justify it with chapter & verse, but the day something one has PAT tested catches fire the next week, HSE or someone might well come looking for your qualification(s) No they will not. As explained by our PAT tester after an item has been tested all it means is that item was safe when tested it means NOTHING else. If something happens to the item it does NOT mean the PAT tester is at fault, neither the machinary or the person doing the tests. Which is why PAT testing is pretty much a waste of time, unless it picks up something that has failed, it can NOT tell you that an electrical product won't go faulty in the future. and evidence of (public liability??) insurance (which dependiing on the size of the fire, you might need to claim on (but perhaps only if you were held to be negligent?)

That is a bit differnt from PAT testing. |
