Hey folks. I just built a shop and I am about to wire in two outlets for my Christmas present(Hobart 210MVP). I am a hobby mechanic who uses air tools and would like to try some painting in the future. I have purchased a couple of 6/50 outlets, two 50amp breakers, and some 6/2 wire. My question is not about the wire size, but how many wires to run.
I see that my 6/50 outlet requires two hots and a naked ground. It is my understanding that the 6/2 wire I purchased will do just fine. Here is where I need some help. I am wondering if I should run 6/3 wire and leave one capped off unused for future possible requirements. I do not know what types of equipment require 6/3, but it is certainly possible that I could upgrade welders or may buy other shop "stuff". Would it be wise to run the extra wire or just go with the 6/2. Would 6/2 work with most types of electrical demands such as a welder upgrade or a decent air compressor?
Any help would be greatly appreciated.
I am ready to run wire as soon as I get your feedback.
