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


I am getting a piece of equipment from europe that is set for 230v- I called the manufacturer and they said it can not be rewired to 110 I should simply run a 230 line= i already have 12 gauge wire ran to the stereo room- Is it just a matter of getting a 20 amp 230v breaker for my elec. panel-
Can i use the outlets I have now and a USA type power cord or what do I need to do?- thanks

The chassis will not get "live" in the event you describe, chassis is wired with ground only, not neutral. The three wires terminated in a standard 110V outlet in a residential setting are Phase, Neutral and Ground. In a standard 220V outlet it is Phase, Opposing Phase and Ground there is no neutral.

Again I strongly recommend that you get an electrician to do this for you this way you should avoid any costly mixups.

You'd need to run a new line from a new 2 pole breaker in your panel to a new 220Volt outlet in your stereo room.

A 220Volt outlet has a different pinout than a 110V one the left pin is horizontal if mounted with ground towards the bottom. Do not wire a 110V outlet with 220V as you could accidentally plug a 110V component into it .

I'd recommend CLEARLY marking the back end if any IEC cord you use too thus avoiding plugging 220V into a 110V component, the back end of power cord look identical.

I have both 220V and 110V outlets in my music room, If you have any doubt how to do this have your local electrician do it for you.

Best of luck

Its actually easier for the transformer to handle 60 Hz than 50 Hz

If its only a CD player with limited current draw Id second the step down isolation transformer, which is likely to cost a lot less than running a new line.

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.

220V outlet

And they have special AC plugs designed for this as well

220V AC Cord Cap

Pretty straight forward - till now - its the back end of the AC cord that you need to pay attention to - MARK it clearly - this way you avoid accidentally plugging it into the back of a 120V component.

Id state again that for a low power consuming device like a CD player that generally don't use more then 10 - 20W just go with a isolation step up transformer you will get much more bang for your buck this way and probably better sound too because of the isolation part.

Hammond step-up isolation transformer

This will plug straight into your wall and here is the plug you need to plug into the Hammond

250V/15A Cord Cap And ill say it again, mark the back end of your power cord!

Good listening

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.
