As you can tell I'm pretty confused about this here wire situation. Any light shed on the matter would be greatly appreciated. Again I'm not doing this myself I'm hiring a professional, but if someone could explain to me what it is I actually need that would be awesome for two reasons.I'll save by being able to buy the materials myselfI'll understand what is happening and will appease my tinkering interestsThanks in advance guys!Last edited by Devareaux; 03-14-2012 at 04:08 PM.Reason: Clarification

Reply:Three wire 230v circuit so you won't use a neutral. Go with the black, white and green.As Ed has said, cut your costs because this isn't rocket science by any means. Do you really need a licensed electrician to hook the two hots to your breaker...there are only two lugs on that breaker...and the ground to the grounding bar as well as the receptacle?Only matter you may have left out is to make sure the conduit attaches to your service panel through the top, side or bottom of the box via a screw connection with a slip on fitting for your conduit to seat into and be fastened by a screw at that location. I find it easier to make that connection prior to pulling the circuit in through the conduit, but if you can do it without the connection and attach later without busting up our conduit and such...so be it.

Reply:First post here. Hope I can help a little. I am not an electrician but I just finished running wire for my garage including a 50amp circuit for the same welder. Let's start at the receptacle. As you said you need a 6-50R. This has holes for two hot legs and a ground. For most welders you only need a three wire cable; two hots and one ground. Four wire systems have an additional neutral wire to supply the 220V supply as well as a 120V line. Appliances like stove use four wire systems; 220V for the appliance and 120V to run the electronics like the display. You can run four wires, but the neutral will not be hooked up at the outlet. You would just put a wire nut on it and stuff it in the box. I would recommend getting the deepest box you can find. 6 gauge wire is not easy to fold into a box. You should use pigtails to connect the receptical to the wiring. Basically pigtails are 6" pieces if wire running from the receptical to the outlet. Screw on end to the outlet and use a wire nut to connect them to the feed. Use a pair of pliers to twist the wires at least 3 times then put the wire but on. Fold the wires into a "Z" pattern and push them into the box. Then screw in the outlet. You can run the wire in conduit or in the walls. Conduit is easier in existing installations. I ran mine in the wall because I was running 3 additional 20amp circuits and didn't wan that many pipes running on the walls. If you run it in the walls you can use 6/2 Romex. Romex is for dry installations only. All of the conductors and the ground are packaged in the outer insulation. You will need to cut the drywall to expose the studs. You should only need to cut a strip about 6-8" wide the length of the run. Get a 7/8 stubby auger bit to drill through the studs. You should be able to find them in the electrical isle at Lowes/Home Depot. Drill the holes in the center of the stud. This minimizes the chances that someone will put a nail through the wire. You also want to use nail plates. These are small pieces of steel the prevent putting a nail into the wire. If you need to run the wire from the garage into the basement you will need to drill through the sill plate. After you run you wire fill the hole with a fire stop (caulk or foam) to help minimize chances to fire spreading between floors. You will need to secure the cable within 6-8 inches of the hole on each side and where it enters a box. You will also want to secure it along any long runs or turns. Basically you want to minimize/eliminate movement. I have never used conduit, but this is my understanding. I think you can use Romex in conduit ad long as it is in a dry location and is sized properly. Basically you are trying to prevent the wires from overheating and starting a fire. I would never run Romex in conduit. It seems a waste of money and effort. You can use the THHN wire in the conduit. I can't help on sizing the conduit. There are tables that take thinks like wire size, wire type, circuit size, length of run, duty cycle, ect into account to determine which size conduit you need. Again you would need a 6 gauge black, a 6 gauge red and a 10 gauge (i think) ground. Use connectors to joint the conduit and cable clamps everywhere you go into a box. If you are running the wires in the basement to your box I think you still need to keep the wires in the conduit. This is to reduce chances of damaging the insulation and starting a fire. At the panel throw the main breaker. This deenergizes the panel, but the mains are still hot! Be careful, don't touch anything around the mains. Remove the cover. If you use Romex run it into the box and use an nm clamp to secure it. Cut the outer insulation off about an inch into the box. Run the wires down one side of the box. Connect the ground to the ground bar. Strip about 1/2" of insulation off each hot leg and attach them to the two poles on your 50amp breaker. Snap the breaker in place make sure everything is tight and neatly run and reattach the cover and turn everything back on.It is really not as bad as it sounds. I had an electrician buddy look at everything before I hooked into the panel. He everything looked good. Sorry for the long post and spelling errors. I'm typing on my phone. Hope this helps.

Reply:Not knowing the type of panel, (there are a lot of split bus panels out there), it should be noted that the entire upper bus remains energized on some panels unless the meter is pulled. This is also the bus where the 2 pole breakers go, and six is the limit. Brush against a live bus with your bare grounding wire or your arm you might get a nasty surprise.Miller Challenger 172Miller Thunderbolt AC/DC 225/150Miller Maxstar 150 STLVictor 100CVictor JourneymanOxweld OAHarris O/ASmith O/A little torchNo, that's not my car.

Reply:6 gauge 2 wire romex (two wire will have a black, a red, and either a green or bare.) Black is hot, red is hot, and green or bare is ground
Reply:Ok, I have to jump in on this one. First off, you either use 6/3 Romex or single conductors in a conduit. The NEC(National Electrical Code) does not allow you run romex in conduit. 6/3 Romex contains 3 conductors(black, white, and bare ground). If it were me, I would run single conductors in conduit for protection reasons. You need to run 1" minimum conduit with three seperate conductors in the conduit. You will probably have a hard time finding any color other than black so just make sure you identify the conductor you use as the ground with green tape. The 2 "hot" conductors do not need to be identified individually. soul5446 you are completely wrong on your last post. Get an electrician to make the final connection of the conduit and the conductors to the panel as you can get yourself in trouble really fast by working in a live panel without proper PPE. If you have any specific questions for me PM me. I am a union electrician with over 20 years experience to pull from.
