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

Jea,

Why do you think there is any "risk" in installing a 220V line in a residential setting. If done properly there is no more risk in this than a 120V line. There are special outlets for just this purpose.

Pbnaudio,

It does not matter what I think. I merely stated the fact that in a residential dwelling unit, per code, it is prohibited in this case.
If you have a 240V window air conditioner that draws more than 1440 Va, that's fine. That meets code.

NEC 2011
Article 210.6 (A)
Occupancy Limitation. In dwelling units, and similar occupancies, the voltage shall not exceed 120 volts, nominal, between conductors that supply,

(2) Cord-and-plug loads 1440 Va, nominal, or less or less than 1/4 HP.

Key words here are "In dwelling units, and similar occupancies,"

"(2) Cord-and-plug loads 1440 Va, nominal, or less or less than 1/4 HP."

1440 Va , nominal or less.

I didn't write the code. The AHJ could care less about the OPs new 230V CDP.

The receptacle and plug you sited in your post are NEMA standard devices and are UL Listed for uses that fall under the guidelines of NEC.

In a commercial building you can have as many 240V receptacle outlets for loads less than 1440 Va you want using the recepts and plugs you linked in your post.
You just can't do it, by code, in your dwelling unit and similar occupancies.

I am still waiting for someone on Agon or AA to post a new thread, who just bought a newly built house, asking about all those breakers in the electrical panel that have a green test push button on them. AFCI breakers.... Audio enthusiasts are going to love them.

Just do what you want. But make sure it's safe. Not for the AHJ, NEMA, NEC or whoever, but for you. In my own house, in this country, I'm going to do what I want whether some pencil-neck making decisions for everyone approves or not. My goodness, look at the NRA.

Do you think the "pencil necks" are sitting somewhere making up arbitrary rules ? Codes are meant to preserve your life and safety.

Quite often, yes:)

Thanks for the clarification I was not aware of that. Sounds like the step up isolation transformer is the way to go.

I obtained my electrical engineering degree in Denmark, where standard household current is 220VAC and each home have a 3 phase supply with 380VAC between the phases and 220V between neutral and phase.

Good Listening
