Adding a circuit breaker

Someone please help. I want to install a 40 amp double pole breaker and run the line ( 8/3 ) to the receptacle for a 225 amp stick welder. The 8/3 line has a black and a red ( Hot, correct? ) and 2 groups of bare wires ( one has

3, the other has 4 wires...neutral and ground? If so, which one goes to the neutral and ground bus bar? ) Also, does it matter which pole gets the red or black? At the other end, the receptacle has 3 provisions...one is marked AL ( copper colored ), one is CU ( silver colored ) the other one green. Which wire goes where?? I'm still left with another group of bare wires...and I'm sure somebody will tell me just where to stick them! :) Any help is greatly appreciated!! Thanks..John

John:

Are you sure both your weding machine and receptacle are 240 volts? Sounds fishey. Your receptacle should have two copper colored terminals, one silver, and one green. For Red, Black, White, and uninsulated respetively if it's 240 as most welding machines are.

I't dosent matter which phase/leg the red and black are connected to but you are correct they are both hot if it's 240.

I'm not sure what 8/3 you have with with two uninsulated grounds. You can pretty much always assume that the smaller conductor will be the ground though.

Be careful
