Wiring a #650-R N.E.M.A. 50 amp 250 volt receptale to main panel.

Dear Sirs: #1). I would like to have some help with wiring this receptacle from the main pannel to the wall receptacle located in my garage (attached to house). I have installed the receptacle and have the wires connected, with the ground wire in the twelve o'clock position, I have connected the black wire in the longer and thinner slot in the eight o'clock position & the white wire connected to the shorter and wider slot in the 4 o'clock position. I would like to know if this corresponds correctly with the power cord for my machine (manufacturer provided).

#2) I have a Square"D" pannel and procured a 50 amp/250 volt circut breaker. On the wire connections (lugs) of the breaker one is designated in the color black and one is designated in the color red. I would like to know which wire to connect to the lug marked black from the receptacle, and which wire to connect to the lug marked red, so as not to injure myself or the machine. Thank's in advance for any information you can forward to me.
* In reading the responses ,afterthought told me that I should have defined "the machine" as a 230ac/140dc arc welder. Thanks again folks for your candid responses. Thank You, AWG

 

1. Yes
2. Doesn't matter

 

Mr. Nelson: Thank you ever so much for your quick and concise reply. AWG

 

One thing that concerned me with your post is that you did not mention what you machine was or whether you have 120 volt components in that machine that would required in insulated white neutral conductor. Is your machine 220 volt only or is there lights or timers that are ran on 120 volts in that machine?

a 6-50R nema number only needs 2 hots and a ground run to it

 

Mike my concern is if he is using the right product. If his machinary uses 120 volts in his design he will need a four wire plug with an insulated neutral with a branch circuit conductor of a red, black, white, and bare.

I firgured he's using the right product because he said in his original post:
