shielded vs. hospital grade redux
In my mind, the shielding is there to keep stray RF from reaching components *outside* the cord, not to necessarily protect the power cord itself. But in any case, a well designed power supply should already filter out unwanted AC line noise...
Checking the Marinco website (the maker of some widely used hospital grade and industrial plugs), the green dot gets you the following:
Abrupt plug removal (parallel to wall) test
Ground pin retention tests
Fault current tests
Terminal strength test
Face impact test
Ground contact temperature test
Ground resistance test
Assembly security test
Mold stress relief test
Cord grip strain relief tests
Static cord pull test
Rotary cord pull test
That being said, if you still want 'green dot' certification and shielding, why not go DIY? Someone previously mentioned the Chris VenHaus design - the Belden cable used (83802) is a 12 AWG two-conductor cable with a foil and braided shield capable of delivering 25A and handling 300 V RMS. Wind a grounding wire around the outer jacket, stick a pair of Marinco plugs at the ends and you've got yourself a great power cord (I have one powering my Heart CD6000 right now). The only drawback is that it'll cost more than $10...
