RE: Arcing Sparking
My understanding is that a spark is the result of an electric discharge through ionized air. An arc actually contains vaporized metal from the contacts and has phenomena like flash and blast that are not associated with sparks.

harmonics testing
We make a product that has several components that plug into the power mains including a computer, two monitors, and two units that we manufacture ourselves. When all these components are tested for power current harmonic emissions together, they fail. When tested separately, they pass. Is it reasonable to assume that if we ship the system to Europe with a power strip that we have to test all components together, but if we do not include a power strip, we can test each component for harmonics separately?

The United Kingdom, by the way is increasingly a disunited kingdom with the devolution of Scotland and Wales, and, of course, Ireland. Devolution is sort of what we did in America in 1776, but without guns. Every time I am in England, which has been a lot, I am struck by the language differences. Churchill supposedly put it as: Two great nations separated by a common language. When a colleague prepares for their first trip to the UK, I prepare them by giving them an American-English Dictionary I found on the Web (as a text file called amlish.txt, look for it, or send me an email and I will send it to you). I also give the dictionary to English colleagues when they visit the U.S. After all, confusion goes both ways. There is an excellent web site, containing upwards of a thousand translations, with humorous commentary. Check out www.effingpot.com . Mike Etherington runs the web site. He just published a book, The Best of British - The American's guide to speaking British, based on the content of the web site. I ran across it the other day and bought it. Even after all my exposure to the British language, I found myself laughing out loud at his explanations. In case you are interested, it is ISBN 0-9536968-0-4. By this time, I'm quite fluent in English, but American words often slip out, with sometimes amusing results. The funniest was the time I had forgotten my rubbers, which is a no-no given the damp and rainy climate over here. I asked someone where I could get rubbers. The stare I received set the wheels in my head turning (yes, I still have a mechanical brain). I realized that they thought I meant condoms. I should have asked for galoshes or overshoes. In fact, many of the pitfalls in language center on differences in terms of a sexual or anatomical nature, best not discussed here. Differences in the names of articles of clothing also have a potential for amusement. Walking through the Marks Spencer's department store, I found signs for Men's slips, and Men's jumpers (translation: briefs and sweater vests). If you need to hold your pants up, don't ask for suspenders. And, don't play golf in knickers. Some of our familiar engineering terms used to have English counterparts, but increasingly, the English are adopting U.S. terminology along with the rest of the World. Accumulators are now batteries, but earth is still earth, not ground, although I hear ground being used in technical conversation. I suppose vacuum tubes are still valves, but then you don't see much of them anymore. Shields used to be screens; maybe they still are, after all, a windshield is still a windscreen here. Fortunately, the English are exceedingly polite, and forgive the occasional gaffes or misunderstandings. Their constant exposure to the best and worst of American television shows has trained them in the American language to the point where many are now bilingual. Now, if I ask where I can get a Big Mac, I'll be directed to the nearest McDonalds, not to a men's clothing store carrying large size outerwear. --- This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.

It is taking a good deal of time to properly set the unit up to do the test, and then remove all of the jumpers before the unit ships. Does anyone have any ideas, recommendations or suggestions on ways to speed the process? Some units may have upwards of 7 contactors and relays.
