First time welding - Electrical questions

[HamAndEggs]

And I appreciate their advice, however nothing says I HAVE to follow their advice. I don't follow any advice, expert or novice, no questions asked. I use that information to decide myself on the way I want to do it

Its quite funny that people are getting grumpy over someone running a circuit. What a world we live in LOL

Still odd to me to ask in the first place and to clarify I would not follow advice no questions asked if I would not know who is posting.

Other reason is that you have skilled members here cross checking each other.

That is way more valuable than talking to a single person in the field imho.

here lemme take some heat off you.

50A extension cord!

You screwed up. shoulda put THWN in. rip it all out and start over. Fight me!

NM is not permitted to be used as extension cord.

 

[HamAndEggs]

Well, it all works. For my first ever time welding, I think it came out alright

As far as the Liquid tite verses Greenfield. If I only had the 2 to choose from, I would defiantly use the Liquid tite. Have you ever tried to get a fish steel through Greenfield at that length.

If you don't pull the wire prior to running it it is a ***** to fish wire through.

Yes, wrap the head with some electrical tape and a little lube. Works just fine

 

[southernfriedcj]

On the subject of wiring welder circuits, is the such a thing as a 50 amp GFCI breaker? What is code for 50 amp receptacle breakers?

 

[wyliesdiesels]

yes there are 50a GFCI breakers. think of a 50a 240v circuit for a hot tub. they get protected with 50a GFCI breakers

If its straight and pulled tight, maybe. But a lot of bends, good luck.

I believe 2020 NEC will require a gfci, but otherwise you don't need one. I believe Wylie has posted a breakdown of the changes somewhere

 

[Terry D]

Starting in the 2020 NEC all 120 volt and 240 volt receptacles supplied by single phase branch circuits 150 volts to ground or less, in a garage will have to be GFCI protected. Equipment that is hardwired does not. Everything outdoors, receptacles or hardwired will also have to be protected, this includes A/C condensers.

This requirement will also have the addition of 240 volt receptacles in certain areas with in a dwelling. So dryers and ranges also, if installed in these areas

A nylon fishtape with a leader will shoot through Greenfield.
The same with metallic sealtite
With Non metallic sealtite it's a no go if it has any bends.

never had an issue

At least to me, neither liquid tite or green field is meant to be installed in place of of a hard metal or PVC raceway of long lengths. They are meant for flexible connections to equipment, or possibly fishing in a wall where it would be impossible to run hard pipe. I use it alot when I have a recessed panel and need to install surface mount EMT out of it. I will fish greenfield in the wall from a 4x4 box to the panel. But yes, it is possible to get a steel through it at longer lengths, but not something I would want to do. Hopefully there would be wire in it already and you can use one as a pull wire.

 

[alfredeneuman]

It's only suitable for certain uses. All flex enjoys the exactly same rule for physical damage as NM so you might as well use Romex
It should be used as little as possible but I was talking about a 5' piece of Carlon 1/2" non metallic flex shaped into a gradual U shape that I couldn't get the tape through.

Nice!
Now lay underneath a 24 inch pipe in a puddle of water as snow comes down from above and stick weld upside while COLD water is running down the collar of your jacket!
LOL!

 

[u2slow]

Prior to 2020 NEC, 240v circuits were perfectly safe without gfci... unbelievable eh?

I don't use gfci's inside my shop. I'm a daredevil

Well Prior to that, we didnt have a electrocution death due to a 240v air conditioning condenser not being grounded properly

240V circuits should have been GFI protected from the beginning.
They're 120 Volts to ground after all.

My dad always said anybody can weld something laying flat on a table.
Now when you're laying under a diesel locomotive on the head end of a coal train rattling and shaking on the main line welding something up,and it needed to be on the road 2hrs ago.
Then youre a welder he would way! Hahaha
