Planning for 1-Phase 230-Volt

[Casey96SS]

I am just finishing some wiring in my garage remodel before I sheet the walls and ceiling with OSB. All off the 115-V outlets are wired and hooked up.

I used these boxes

With these mudrings for all the 115-V stuff.

I want to add one box that I can add a 230-V receptacle for a future welder or compressor use. I will be running 8-2 NM cable to the box. Not going to install a receptacle or make it live yet. Just want the cable and box there for the future. I just have a few questions.

1. Would the box and mud ring above be ok for what I am trying to do, or is there something more versatile?

2. Would there be any reason to run 8-3 instead of 8-2? Would a welder or compressor ever need 8-3?

it depends on the welder or compressor. many stick welders require 50a circuits so the 8 ga will be undersized for that. if you are planning for the future consider installing flex or other conduit so you and pull exactly what is needed in the future. i would use a deep box and a 2 gang ring for the rough in

The 2 conductor and ground is sufficient as is the 8 for generally any diy welder or comp you might connect to it.

Thanks for the replies guys. I don't plan on get a real large welder or compressor. From my reading is sounds like #8 would be plenty big enough for my plans. I was a little concerned about what box to use but I found this one that will extend through the OSB so I can put what ever cover plate on that I need and I do not have to worry about it being burried behind the OSB.
