You know the fact I can downsize the conductor has me wondering

I could legally go down as far as #14 THHN. So why not strip the insulation off this 6/3 and use that in conduit? I might just do that

Because it isn't rated for that application. Wire is more than the gauge.

Will it work? Yep. Will it probably be just fine? Yep
Should you do it? No, but if you don't care about code, nothing is stopping you

I'm tempted to go three different ways to be honest

1. Throw this 6/3 in Conduit (Strip it first) and call it a day. Save $200~ on wire
2. Go all out with #8 THHN
3. Go with #10 THHN

I think all three would be fine, this will never be inspected.

If I go with #10 THHN, then I honestly may as well just run with the old #6 in conduit. And if I'm going to do it "right" then just go with #8 from the get go

8 is no more right than 10. The only "wrong" option is stripping the 6 NM

The pros have given you input. Take it or leave it at this point. No need for a "vote" if you have already, really, made up you mind to use the NM hack job. I regret looking at the other thread before reading the last few posts in this one now. To do it right for your welder, 10awg is great.... to do it right for 50amp full time, bite the bullet for 6awg.

I'm actually thinking of running with a 50a breaker, and using 8 AWG THHN inside liquid tight conduit. Might make for a cleaner install since my garage has no walls up currently

It should work out cheaper too
Why liquid tight? Its inside right? Just run some PVC conduit. LT wont be a cleaner install vs conduit

Because the individual conductors are not labeled, nor are they 90* rated...

Why be pennywise and pound foolish?

Just scrap it

Alright you guys wore me down, I went all out. I can use the same wire for some other projects

What I'm not doing though is buying another spool of green or white, so taped green will have to do!

That's a lot of money to spend and not even do it right, but to each his own

There's right and there just money making. I'm not buying a bunch of extra green for this. I can't possibly see why taping green is not good enough

Funny how in the pro-gun threads we all talk about how we will not obey dumb gun laws, but suddenly green tape gets everyone to comply with dumb rules...

What possible safety concern will come with the wire not being green inside conduit where no one will see it? The wire will not grow self aware, realize its not green and stop being the ground conductor

I don't know who you are talking about with not obeying gun laws. I am a law abiding gun owner, but that is completely irrelevant.

Like I said, do what you want. If you don't care about code, ignore it. I don't care. I was just pointing it out.

He is from Texas, and a lot of the folks here think everything is a "god given right."

You'd have saved a lot of money by running #8, which is rated for 50a, and EMT (using the EMT as the ground. As an added bonus it would be Code compliant).
Too often people come here asking for advice on something they don't know or are not sure how to do it, so they ask & don't like what they hear, so just do it the way they please, code compliant or not.

Edit: my comment is a bit harsh but am not feeling very good, have long covid because of damaged lungs & that is the way I see it.

And then there are others that come here, ask questions, ask more questions, figure out they messed a step up, fix that step, and then keep coming back to just read and learn more about electrical stuff. :) This forum is a great resource and the pros that help out are appreciated GREATLY!

People here, and especially in this thread seem to have forgotten that I never went to the code office and asked how to do it, I made a thread on a forum about garages and asked some opinions. Nothing says I have to do my work and follow those opinions to the word. I appreciate the posts here, and I've used the information to decide on what to do.

In my view, this is like a bunch of guys hanging around the grill discussing stuff with ideas getting thrown around. People are taking things FAR too seriously.

Also, the amount of people here wanting things to be done exactly to 2020 NEC and nothing else is just hilarious. Go look at everyones post history and see how many code violations you can count. They are everywhere

I bet there isn't a SINGLE person here with a garage with everything to code

Either way, the discussion on wire, and the welder rules were good information. I'm glad I went with liquid tight, made it much easier to get around my wonky garage

That 6/3 is NM sheathed cable, which is rated for 60° C, current NEC requires 90°C rated NM (NM-B), scrap the wire as it cannot be used in a code compliant manner.
50A extension cord!

Why LT? That screams hack for an indoor location. And its expensive

You couldve used FMC/greenfield and saved some money.

Did you drill a hole in the plastic box?

For how it goes above the ceiling joists in my garage and up and over some supports, LT was much better than PVC (Or anything non flexible for that matter)

FMC here is about double the price of LT, not sure if that's normal or its shortage related. FMC at Home depot for 25ft was the same as 100ft of LT

Not really sure what the issue with LT is, good protector for the wire which I wanted, flexible, easy to run, and cheaper than the alternative.

Yeah I drilled a hole in the box for a fitting. I can't find anything stating you can't drill a hole in the box

I've never seen someone's feeling so hurt over their advice not being followed

Lighten up man
You might not realize that but you have a handful of very skilled electrical experts here which give advice I have and would follow no questions asked for free.

Not sure why you ask for guidance only to disregard it.
