Hello Brian, You can ship Class I devices with a fuse only on one side and with a non-polarized plug as long as the plug is a grounding plug. Mr. Woodgate is correct in his analysis. I have had VDE specifically require the marking of IEC 60950-1 section 2.7.6 for this situation. That clause is intended for when there is a fuse in the neutral and you have a non-reversible plug. However, VDE interprets the clause to be appropriate for whenever you have a risk of portions of the equipment remaining energized after a fuse opens.
Let me state that I've only heard this as an interpretation from VDE and I don't have anything in writing. I am unaware of either a CB Scheme CTL Decision Sheet or UL PAG on this specific clause regarding the use of non-polarized Class I plugs.

Some of my custom products only have line fused (customer's requirements), so cannot allow my factory to ship affected Class I stuff with this cord. So when will EU/EFTA code get these plugs and sockets on the same sheet of heavy metal music? This seems to be a good excuse as any for another war... Any other ideas? thanks, Brian -----Original Message----- From: emc-p...@ieee.org [mailto:emc-p...@ieee.org]On Behalf Of Ted Eckert Sent: Monday, January 23, 2012 6:18 PM To: EMC-PSTC@LISTSERV.IEEE.ORG Subject: RE: power plugs Hi Brian, You will want the CEE 7/7 for most of Europe. It works in almost any European outlet that doesn't accept one of the three that you mentioned. The BS 1363 covers the UK, Ireland and Malta. The SEV 1011 only covers Switzerland. Make sure your supplier conforms to the new SEV 1011:2009 since Switzerland will require partially insulated pins next year. The CEI 23-16 will work only in Italy.

Where I need ground pin, was thinking of reducing types to CEI23-16, SEV1011, and BS1363A. Is this a stupid idea? Am I missing a major European plug type? thanks, Brian - ---------------------------------------------------------------- This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.
