A stupid question(s) about power cords
As the title indicates, I admit that this is probably a stupid question. But since I don’t know (for sure) the answer, I am asking it anyway.
The recent power cord thread got me interested in a power cord upgrade (from the stock cord) on my Maranzt SA10 (SACDP). The power cord receptacle on that particular component does not have a male equipment ground pin--only the neutral and hot pins. Therefore the cord supplied by Maranzt is a two pole (if that is the right terminology) cord. But because I have done it this way before, I do know that it will accept a power cord with an equipment ground as well as a neutral and hot.
Question 1: I went to musicdirect and looked at some power cords and I saw one (an open box Audioquest NRG Z2) that they were calling a two pole cord. The end that plugs in to the component only has a neutral and a hot, but the other end, the end that plugs into the outlet in the wall, does have an equipment ground blade (so that end has three blades). Why would that be?
Question 2: (and this is the stupid one) if a power cord has an equipment ground pin plugged into the wall, even if it is not plugged into an eqipment ground in the component itself, that cord is still connected to the neutral bus bar in the panel, right? So that being the case, since the equipment ground wire in the cord is right next to the hot wire, is there a way unwanted stuff (rf or whatever, my understanding of this is quite limited) can that dirty up the power that is traveling on the hot wire in the power cord?
I think that the answer to the last question is probably going to be ’no’? And if the answer is ’no’, that means that I really don’t need to shop for only two pole cords, right? And I see this as sort of important because if I buy a two pole cord, the ONLY component I can use it on/try it out on will be my SACDP--there will be no playing around with a two pole cord on my preamp or my amp.
And ALSO, if I don’t feel constrained to shopping ONLY for two pole cords, I would probably have more options to consider.
TIA for legitimate insight to this, and to all others, feel free to ridicule me and my question--I don’t mind.
Just use a three cord plug. It will be fine. As to whether it will shield RF, that is not the point of the third conductor, which is to ground the chassis of the electronic equipment. Oh, and burn it in, freeze it, bury it in dirt for 30 days, have it blessed by your local priest and spray Synergistic Research Audiophile Water on it. Sheesh...

@jea48 , thank you for your thorough answer to the question. |
@grislybutter , If that’s to me, I actually know almost nothing at all about power cords and that’s why I am so hesitant to take the plunge. But as far as making fun . . . I did preface the thread by inviting ridicule, so I have it coming. I am glad I checked with you before I took the wet towels down from behind my speakers. |
