DIY power cable questions

Hey there,

I’ve been looking into making my own power cables for a few components and it’s easy to find connectors for the IEC C13 and C15 receptacle configurations but I’ve not had much luck finding anything for C17 connectors that just have hot and neutral wires but no ground. Same for the NEMA 1-15P connectors. Way harder to find anything compared to the NEMA 5-15P versions. Anyone have any advice or info to share on this matter? I appreciate the help for sure.

Even if the power cord/connector uses all 3 conductors, the equipment it's plugged into will not use the ground conductor. All is good.

 A question on floating grounds?? 

I have a two 1200 watt DSP plate amps from PE, the same thing you just mentioned. How does it get a ground? Floating? There is ZERO floor noise. I haven't had any problems, but could I? I was gonna make up a good PC for the two, plate amps. There is no safety issue? Mixing grounded with a floating ground? Can there be issues? Hope I'm not off topic.

How do you weave a cable with no ground wire, to eliminate noise, I understand how "IT" works, just wondering what to do in lue off it?

You might want to google "floating ground".

You know I did, I need to look a little closer. Thanks for the info..
Pretty short, said something about floating voltage too.
Safe is always a concern. thanks
