Jeff's explanation is correct, except that cheater plugs now only come polarized (one wide blade) so if you want to use them as he describes, you'll have to file down the wide blade so it wil go into the socket either way.
AC cord polarity?? Does it matter???????
I've just noticed that from experimenting with preterminated factory builty cords that not all companies use the same polarities. Even with two stock cords, one from USA made in China and one from China made in China for USA the polarity of the cords are reversed. All my Synergistic cords are one way, my Electraglide is the other way and other cords from different manufacturers are different. The poles are reveresed from one cord to the next. Now I'm really confused to the polarisation issue as if different companies use one polarity and other companies use the reversepolarites, then it's a guess wether or not one system is in the right polarity or if just certain components are properly polaroized. It appears that in the US made cords I've noticed both direct and reverse polarity in cords. The Asian made cords are different depending on company as well. Does this then mean that polarity has no issue and it doesn't matter? Is there no right or wrong way to polarize a components ac? The cords in my system are giving half my components one direction of ac polarisation and the other half are in reverse.Perhaps it doesn't matter? I'm confused again!!!!

>>"Of course if you decide to use a balanced power unit, all this is of no concern."<< [Nsgarch] >>>>> Maybe, True if all the audio equipment connected by ics is pluged into the same balanced power unit. ========== Nsgarch, What is your thoughts of feeding a balanced power unit from 120V? Jmho, I believe there would be better isolation if a balanced power unit was feed by 240 volt. Here is some reading material. Make note of how the utility companies bond the high voltage neutral and all the secondary neutrals together at every utility transformer. This can't be good for AC noise.... http://www.mikeholt.com/documents/strayvoltage/pdf/DangersofStrayVoltageandCurrent.pdf Jmo it appears to me the only way to get total AC isolation is with an isolation transformer fed from 240 volt.
