Such construction cannot be sloughed off in such an off-hand manner. This is solo BOGSAT engineering, which cannot be condoned. Rather, the scientific method must be applied so as to reach a conclusion that has a foundation supporting the conclusion. 1. Statement of the problem. Board traces to a board-mounted IEC 60320 applicance connector cannot withstand the prospective short-circuit current. 2. Hypothesis as to the cause of the problem. The cross-sectional area of the connection from the board trace to the 60320 connector is insufficient to withstand the prospective short-circuit current. 3. Experiments designed to test the hypothesis. Design a set of boards with different cross-sectional areas of the connection of the board to the 60320 connector. Apply the test to each board. 4. Predicted results of the experiments. Where the cross-sectional area equals or exceeds that of the supply conductors, the connection will not fail. 5. Observed results of the experiments. TBD 6. Conclusions of the experiments. TBD "The real purpose of the scientific method is to make sure that Nature hasn't misled you into thinking you know something you don't actually know." -- Robert M.

Whoever the product manufacturer is needs to verify their compliance with FCC regulations for Customs. This is not an uncommon circumstance.

Hi everyone. We have been working through consequences of the New Proposed Emc Directive. As we are not a large electronics company so we will not be able to quote all the standards we quoted today as we don't use equipment detailed in that said standard. The new directive states we will have to establish technical documentation which enables conformity to be assed, which would include design and manufacturing information as well as test results. No doubt detailing the instrumentation used as well. This is going to make for a very large file for each product. There is also the point, that we buy in products and put the Spirax label on it. Upto this point we have excepted a suppliers D of C. Across the company this a large number of products. We would be left assessing if a supplier was complying by reading his technicial documentation. The amount of paperwork this would entail is a bit overpowering to think about. Have we been reading the Proposed EMC Directive correctly ? Thanks Ian

This is the claimed justification for the introduction. Field problems have occurred where printed board conductors have failed in high-current short-circuit conditions. The printed-board mounting versions of the IEC 60320 appliance connector encourage the use of board traces to carry the PEC; something that I would not be happy about, in principle. > >The existing test has its faults but it is easy to do with some very >cheap apparatus.

I don't understand that. You mean that if people cheat, safety will be compromised? That's always the case.

230V Transition for EU?
EMC-PSTC'ers, Some of my references on international primary power say that the European Union was to transition to 230V power in two phases: * On 1 JAN 1995 the United Kindon and other countries using 240VAC were supposed to declare that their power was now 230VAC +10% -6%, while the countries using 220VAC would declare that their power was now 230VAC +6% -10%. * On 1 JAN 2003 all the countries in the European Union would declare that their power was now 230VAC +10% -10%. Did that actually happen? Can you point me to any official documents to that effect, maybe in the Official Journal of the European Communities (OJ)? Thanks!
