Default 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

Looks like this setup is same as my 220v table saw. You only need 8/2, not
8/3.

Breaker box side
-black to breaker, pick a slot
-red to breaker, the other slot
-bare to ground bar

Outlet
I am assuming that this is the correct outlet, rated for the draw (Amps) and
is correct for your equipment.
black to AL
red to CU
bare to green

You can leave your extra wire unused. There is no neutral in your setup,
just 2 hots and a ground.

Anyone have anything else to add?

I think he's just reading the outlet wrong. The CU-Al means it's for copper
or aluminum wire. The bare wire goes on the green and the other two don't
matter. Like you said, he doesn't have a neutral, so he only needs three
wires

Right, "CU-AL" is a rating designation for the _whole_ receptacle.

The fact that the terminals are two different colours, however, suggest
that perhaps he's using a 120V socket instead of 240V. The colours
suggest that it matters which way around the wire goes, much like
you get different colours on 120V outlets. With 240V, it don't matter.

Is it possible that this is 8/2 cable, and all the bare stuff is one
bundle of 7 bare wires? In which case it's ground and there's no
neutral. This would be normal for most welders, which are 240V only so
they don't need a neutral.

It would be weird if one were really a bare neutral, since neutral
should be insulated in white right up to its connections.

Also, does it matter which pole gets the red or black?


No.

My guess is that "Al" and "Cu" aren't markings for each screw, but that
the outlet is marked Al/Cu indicating that Aluminum or Copper wires are
acceptable, on all screws.

The green screw is ground, that's easy. If the outlet is for 240,
usually the screws are marked X and Y, and it doesn't matter which gets
red and which gets black. When screws are coloured, the copper or gold
one is hot and the silver or grey one is neutral, but that's for 120V
outlets. Try to find your receptacle pattern in the chart at
http://www.leviton.com/sections/techsupp/nema.htm and tell us which one
it is. I think it *ought* to be 6-50R, or maybe 6-30R.

i just wired up my new 240v compressor, and the 6-50 plug i got at home
depot did have 2 different colored screw attachments for the 2 hots.

Thanks to all for your replies but I'm still confused. I have pics of the
breaker, wire and receptacle but don't know if I should post them here. The
receptacle is definitely 2 prong 3 wire 6-50R and the wire has Red, Black,
and TWO seperate bundles of bare wire...one with 3, the other 4. The wire is
marked TYPE SE CABLE STYLE U THHN OR THWN CDRS 3 CDRS #8 CU 600 VOLTS E73061
(UL) if that helps.

John, I think your two bundles of bare wire may have been one bundle that
came apart. Your description is a three wire cable. Twist all the bare wires
together and connect them to the green terminal on the outlet. Connect the
red and black wires to the other terminals in any order. In the panel,
connect the bare wire to the ground or ground/neutral bar and the red and
blacks to your 40 amp breaker

Type SEU cable is for service entrances and at one time was approved in some
places for electric ranges. It has a single bare stranded neutral which can
easily be separated into two groups. It is not approved for this application
anywhere I know of although it will "work". Get the right cable and follow
the codes, which are only intended to provide a safe installation.

I would agree that 8/2 Romex would be a better choice, but there is no code
violation in using it as a 240 volt with ground feeder. Only on a service
entrance can you have a non insulated neutral, but in his case, he has no
neutral only the two ungrounded conductors and a ground

I'd place more confidence in the local electrical supply house. Go ask the
counter man there. Internet people, well, you'll get some screwey answers.
And then you'll get a bunch of flamers telling each other they are wrong.

Want to risk your life and house based on what some anonymous writer says?
