I purchased a Server (Computer) and would certainly like to make use of it without putting a 120v to 240v power converter between the server and the wall plug.

My concern is the following: The server runs on 240volts current only, but it's plug is a standard one like on every 120volt electric apparel !!

The option of putting a power converter between the server and a standard 120v electrical outlet is what I do right now

but I don't find it very elegant.

The question I have is this: Does it make sense to put a 220v breaker, and to run gage 12-2 cable up to the computer, and make use of a standard 15Amps 120volt wall receptacle?

I wish there were 15 Amps 240volts wall receptacles exactly like the 120volts, so I can plug in the server, but all "standard" wall receptacles I found at home depot are specified 15Amps 120volts. Can they run 240 Volts? Is it safe? Is it better to purchase one with a "test/ reset" button on?

Or should I forget about this ideology of removing the power converter in the middle which I'm using right now, and just stick with it?

Any suggestion or insult is welcome!

Thanks in advance!!

The only proper way to do this is to install a NEMA 6-15 pr 6-20 receptacle and a 6-15 plug on the server.

Having 240 volts on a 5-15 or 5-20 plug or receptacle is not only just WRONG, but is also dangerous.

Whether you get the 240 from the panel or use a transformer it is still WRONG!

But I am very suspecious of this. Either the company that made the server screwed up or you have misread the requirements.

Please post the FULL information that is on the label giving the brand, model, voltage and current requirements.

I am assumign that you are in the US or Canada.

Is this computer certified by any Nationally Recognized Testing Laboratory, such as UL? I'm having difficulty believeing that a piece of listed equipment would come with a cord for the wrong voltage.

But I definitely am curious. Please post the info that Bill requested, I'd like to see where this goes.

I must be an idiot. In fact there's a little red tab on the server which can be glided to select either 110v or 220v.

I received the Compaq server with the tab set to 220v, and the only power cord I received with it was standard 110v power cord. On Compaq web site, they mention that

220v power cables are available. Cables snap in and out easily.

You're correct, I'm located in Canada. I'm still puzzled on why they make these systems

to work on both 110v and 220v, any reason you see for that?

Anyway, thanks A LOT !!!

mystery solved.

In Europe and many other countries 220 to 240 is the standard supply voltage.

A lot of equipment now days uses switching power supplies and you will that they are marked to indicate that they will operate off of 100 to 250 voltages without any changes. Often you will see that on monitors.
