RE: What happened to the IEC60417 symbol library?
Surely IEC 60417-1 and ..617 are different standards? The former is Graphical Symbols for use on EQUIPMENT... (my emphasis).

Re: 2 Phases in North America
ok folks. This topic needs to be clarified. With respect to each other, by definition, two conductors have a potential difference at 180 degrees. Period. The 90 degree stuff may pertain to current but not to voltage. You would need a four-phase transformer to get 90 degree phasing and simply it does not exist. Voltage, is usually measured: wrt ground, wrt other reference conductor such as neutral or wrt to another voltage (hot) conductor. In some cases, the voltage difference between ground and two other conductors may be 120/240 degrees such as in a three phase system. So, no matter how you measure voltage it will either be at 120, 180 or 240 degrees wrt to some other conductor. In the US there have been many systems of low voltage (staying below 480V)distribution yielding the following voltages: 480/240/120 480/208/120 from three three phase 480/230/115 single split phase 230/115 single split phase motor control voltage 220/110 single split phase older home voltages 208/120 from three phase 480/277 (for fluorescent lighting) 117 (where did this come from? seen in many older HP instruments) Open Delta (3, 4 or 5 wire, when one is grounded into neutral its called a stinger) Split phase (three or four wire) Y (four and five wire) Hope this stirrs the pot = Best Regards Hans Mellberg Regulatory Compliance EMC Design Services Consultant By the Pacific Coast next to Silicon Valley, Santa Cruz, CA, USA 408-507-9694 __ Do You Yahoo!?

RE: 2 Phases in North America
Hi all, Even though I am an electrical engineer, I'm terribly confused by this post. I have always believed (and on a few occasions measured) the standard US home system feed. There is no choice of 240 volts. The 220 volt feed used by larger devices is two 118 VAC phases 120 degrees apart. The math seems to work. WRT Cortland's post, I guess I don't see ground (or close to it neutral) as having a phase. If that is believable, then a single phase system is not so hard to believe.

Re: Sometimes product safety just isn't enough
I think it's worth mentioning interpretations of the definition of end user in 950. In my opinion, end users are obviously people who use the equipment and are also not expected to be aware of the hazards. That's why, in my opinion, the thread about safety critical parts was so difficult to pin down. We as safety engineers know some rather obvious hazards which could occur during design, assembly, and use. But, in selling to the general consumer market, the product is being put in the hands of maybe uneducated or non-technical people of a variety of ages. As such, you have to anticipate little to no experience or knowledge. Regards, Doug McKean --- This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.

Re: Regulatory General Discussion : ouput of Compliance group
Andre, Pierre-Marie wrote: So has anybody some thoughts or argument on the measurement or evaluation of an Compliance Group ? Well, I'd hate to let the dirty little secret out of the bag for those of us who would fall under such and evaluation. Important in such an evaluation would be that the company has allowed the compliance engineer to have significant input to the design/mfring processes. I've been in companies where evaluations from the compliance engineer amounted to nothing more than a suggestion. Very frustrating. Other places had the compliance engineer greatly involved as a signatory in product release and with ECR/ECOs. Start with an ideal world where the compliance engineer has complete planning, budgeting, signatory/approval powers with the complete product cycle from prototype-to-product release-to product obsolescence. Consider that as the complete model. Then, as the person has less and less involvement/approval power in those areas, they are thus less responsible for them and thus, they are not to be evaluated in those areas. You'll probably find the typical compliance engineer ends up in reality scheduling tests w/no approval powers, has input to ECR/ECOs but no signatory powers, inputs into product design by way of memos, sometimes are the last to know about significant design changes, and might answer to someone who knows little about compliance engineering. IMO, evaluation would be difficult. Regards, Doug McKean --- This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.

Well, you can also look at it as a two-phase system with 180 degrees between phases. But since the load is very rarely balanced, so the neutral is normally a current-carrying conductor, it doesn't really meet the criteria of a poly-phase system. -- Regards, John Woodgate, OOO - Own Opinions Only. http://www.jmwa.demon.co.uk After swimming across the Hellespont, I felt like a Hero. --- This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.

Re: Sometimes product safety just isn't enough
I read in !emc-pstc that Nerad, DarenHS-SNS daren.ne...@hs.utc.com wrote (in 47c2376d5478d4119fa800508be390ee025be...@hsmx53nt.rkd.snds.co m) about 'Sometimes product safety just isn't enough', on Fri, 14 Dec 2001: and that of Wile E. Coyote and his equipment from the ACME (obviously, most of it was not safety approved)) My impression is that it does exactly what it is supposed to, but the user does not follow the instructions. In fact, have you ever seem W E C even read them?

Re: Sometimes product safety just isn't enough
In deference to the warning label on the peanuts bag. Some people have life threatening allergies to peanuts and take warnings such as that and warnings on cookies, etc very seriously. But then again, you'd think with the main label Peanuts would be sufficient. Perhaps, someone is making peanuts out of soy beans already. - Robert - Robert A.

I was thinking that in a similar style that maybe electrical products could have an added warning may contain electricity. The may would elude to the connection of a mains cable for mains powered equipment, or even batteries in battery powered equipment. I think the IEC should be prompt to act in this vital area. Following this illogical train of thought, the swimming pool should have a warning contains water and the ladder could have a warning may alter altitude. But on a slightly more serious note (but not much) If I am ever present when someone is about to do something interesting with electricity I always advise that the person about to do the deed make sure to note who present will provide the kiss of life when it all goes pear shaped. It tends to work (although I don't know why, as I think I'm very kissable).
