how to run a 230 volt line from my panel??

If you are intent on doing this then get an electrician in. There could be MANY code restrictions that need to be followed.

In north american homes 230v is generally reserved for stoves and in some cases heating.

Connecting a 230v component to another of 120v may also present a problem.

Best solution - get a steup transformer - at least they are designed for the job.

One last comment - consider your household insurance policy!

Companies do anything to get out of paying for damage - your solution might just be their "get-out-of-jail-free" card?

Of course, this applies to ANY DIY "power related" project.

Having said that, many Agon'ers probably live with this on a daily basis :-)

Something to ponder - may good fortune always smile upon you, whatewver your solution.
