For the receptacles, I was planning on using 4x Furutech GTX-D NCF(R) AC Receptacles. Is there anything better?
Dedicated 20a lines, 125 feet distance, which gauge wire to run?
Want to set up 4x dedicated 20-amp lines for my hifi system. The distance from the outlets to the breaker box is about 125 feet. What wires should I use? 10, 8, or 6 gauge? And should they be solid or stranded? If you could be as specific as possible that would be appreciated (brands, links, etc), as I am out of my depth here. The wire will need to run underground for a good portion, and then into craw space, if that makes any difference.

My experience with rhodium plating is it is very pretty but a terrible interface to another surface. It is too hard to allow for a great grip. Copper alloys, like on a normal wall socket or spade, are soft and deform readily. This malleability makes them deform and make a more complete and tighter connection to another metal. This is something you can readily feel when making a hard to hard surface connection, like nickel to nickel or rhodium to rhodium. It never feels as tight and secure than compared to using a soft to hard or soft to soft connection. For instance, a nickel plated speaker connector has a very hard time staying tight onto a hard spade. Switch the spade to say gold over copper or the WBT spring loaded spades and the problem goes completely away. I have also used rhodium AC connectors and faced the same problem. They just do not grip or stay in the outlet as well. The worst high end connector I ever used was a Furutech locking banana. Maybe I got a fake one, but it was just like half a millimeter too small, and the rhodium plating was TOO smooth. It was nearly impossible to make a strong speaker connection. The inexpensive solid copper spades were far superior and a lot less expensive. Not saying you should avoid Furutech, but all of my experience in various locations (AC/speakers, etc) says rhodium is not very good except to look at. |
I’m not saying you should avoid Furutech, but avoid Rhodium plating. Oyaide and Leviton are fine brands as well. Here’s a great source: https://www.partsconnexion.com/ac-receptacles.html Chris is a great guy, I’d literally call them for advice. If you stick with Furutech, I'm going to recommend the gold over copper as a much better performing outlet: https://www.partsconnexion.com/FTECH-74278.html |
