Lousy IEC Connections

Fuzz- I debated whether or not to reply to you, but decided that I should.  There are some companies (Audience and Synergistic Research) that do use twist lock connectors on their power conditioners.  Trying to get hundreds of manufacturers to agree to use a different connector than they currently use is not only an uphill struggle- it is climbing Mount Everest in a blizzard.  Just not gonna happen.  There ARE some solutions for you- friction tape on the outside of the IEC to make it fit snugly costs very little and is very effective.  If your power cords pull out of the wall, rotate the duplex 180 degrees and have the ground hole at the top.  Two very quick, inexpensive solutions that should work for you and satisfy the urge to complain further.

rpw - now I get it.  You DO know that the specification for IEC's on components ONLY specifies the dimensions and location of the actual connectors NOT the cup that they fit into.  This is NOT a manufacturing issue- it is an issue with the lack of specifications for the cup!  Use the recommended "patches", because the specifications are not going to be enhanced or changed at this point.
