I'm trying to wire a new line into my breaker panel, 10-3 wire, a 6-30 outlet, a30 amp dd pole breaker, where do the wires go ? Wire is black, red , white, and a copper ground, the plug says 2 pole 3 wire, what's that mean. Thanks

Yeoyeo,

First, working in the electrical panel can get you very dead, very fast! Your question leads me to doubt that you have the requisite skills and knowledge to do this level of electrical work. I urge you to call an electrician.

However, if you are determined to do the work yourself then if you are planning to install a 240/120 VAC 30 amp line, then you need to do the following:

Visit the LAJ and pull a permit for the work. All work will be required to be up to code. An inspection will be given to the work at the completion of the rough in. Your work must pass the inspection.

1) Turn the main power OFF to the entire panel.

2) Find two breaker posts that are in tandem (one on top of the other)

3) In the PANEL - Black goes to the first breaker post. Red goes to the second breaker post. White goes to the Neutral bus and Bare equipment grounding conductor goes to the Ground bus.

4) At the Outlet: Size the outlet box for the installation of a 30 amp receptacle, the 10/3 conductors and any clamps or yokes you need to install.

5) Black will go to the (B) Blade. Red will go to the (R) blade. White to (W) and Ground to ground.

I urge you to consider calling an electrician!

Don is right about the wiring of this, except for the white wire and the 120v part. A 6-30 is a straight 240v receptacle. NO neutral is used.

Since you ran "3-wire" just cap off the white wire at the receptacle box. You can terminate it in the panel if you like.

I also agree with Don that you should seriously consider calling in an electrician for this. The extremely vague and broad way you are asking is quite concerning that you may not be experienced enough to do this.

Did you size the boxes right?
Are you familiar with the codes involved with running the cable?
Have you worked in an electrical panel before?

I know it seems easy and is not "rocket science", but the consequences of doing it wrong can be devastating.
