Italian Machine with 230v Electrical Connection


We have recently purchased an Italian machine. The manufacturer has sent me specs that the machine requires 230v Single Phase 60Hz, 3.2 Amp service. And it MUST be earthed/Grounded. Allegedly, they are shipping it with a standard 3 prong US 110v type of plug. The machine will NOT be hard wired. It WILL need to plug in to electrical service. So I have an empty 220v 30Amp breaker circuit that is not being utilized. My question is how to connect the electrical service to the receptical. I know... if I have to ask then I need someone else to do it... I am not going to do the work, I am just asking HOW it is going to work.

Thank you in advance

Well, that certainly doesn't make any sense, does it? Are you sure you didn't misunderstand?

Nope! That's why WE'RE all here! This IS a DIY forum after all, and this is not a hard job when done correctly and safely.

Well, I am not completely positive I did not misunderstand. but his statment of "Electrical connection: It is like the one of a normal computer ". My computer is on a 3 prong connection. I just don't understand. We may run a 10-gauge 4-wire connection to the proposed location and wait until the machine arrives before we connect the receptical. Any other thoughts??

If it is 240v single phase, you only need two hots and a ground.
At 3.2 amps, you can run that from a 15 amp breaker.

Sounds like an IEC connector:

That standard supports 120 or 240V on the same connector. So all you need is an IEC power cable with a 240V plug on the end to match whatever 240V receptacle you install. You'll probably want to replace that 30A breaker with a 20A so you can use #12 wire and a standard 20A 240V receptacle (the kind with two horizontal prongs).

You are correct. But that is the machine side, not the receptical side. It makes sense that we will be able to run hot to hot, hot to neutral and ground to ground (from circuit to recepticle). Thanks for the tip on #12 wire though.

Be careful how you use the term 'neutral'. I think I know what you mean, but its not written correctly. You will have two hot conductors (from a 2-pole circuit breaker) feeding the receptacle.

You could ask me due I live in France for a quite a while and let get to the point the word netural they are same meaning but the voltage appaiction { useage } will really get you off gaurd if not heeded on this one.

As you are aware the North Americiané 240 volts system do not have netural in there due they are line to line format and the European 240 volts system typically will have Line to Netural connection { very few case may have 240 volts Line to Line but very limited use in our area }

And the same thing with colour codes the North Americiané 240 volts will use Black and Red which it is the most common colour but can use other colours as long it is not White , Grey , Green or Green with yellow stripes those four items are off limted but for Our European colour the Brown is line while Bleu is typically used for netural { there is other legit colour but I will leave it off for now }

So which it mean when you get the equiment verify to make sure they are properly connected to NA 240 volt system sometime they will provide you the wiring diagram as well if so all by the means to verify it.

Merci,
Marc
