Hello everyone,

I have a friend moving from UK to US and wants to bring his equipment including some DSP520s over.

240v (or 200V) is available at his new location in the US but I think it's in a 120v+120v configuration.

Will this be ok, or does the full 240v need to come over a single lead?

Thank you!

It is fine to use, just be aware that earth sits between the two split phases. It will be one lead taken from a 240v double breaker.

There may be existing spare outlets otherwise just add an additional 240v breaker and appropriate cabling.

Clearly one needs to know what one is doing and / or get in an electrician as needed.

Thanks for the reply John!

I'm a little confused though, are you saying a HOT(120v)-HOT(120v)-GROUND will or will not work?

I understand that the ground will sit between 2 phases, will this be ok for the transformer?

It will be a little pricey to get a HOT(240v)-NEUTRAL-GROUND because there is no circuit in the house. Even the AC which runs on 240v is double 120v hot leads but the electrician said HOT-HOT-GROUND is easy peasy.

Thanks again!

Hot to Hot is 240. It should work fine.

The ground is not "functionally" used, it's just a safety ground.

A short from either hot to ground will trip both hots.

You won't be using Neutral.

When you get to the USA if your Electrician is confused.

Tell them you need a Circuit for a 220V Air Conditioner. That is about the most common need for a low amp 220/240 Circuit in the USA. 15 or 20 Amp will be fine. 1 to 2 Circuits.

Typically the Air Conditioner Circuits are 1 Outlet (i.e. dedicated). But that doesn't need to be the case.

You will need to get the correct power cables. Which won't be the same as UK 220 or USA 120. They are slightly different for 15 amp vs 20 amp.

Personally, I'd go with 15 Amp.

You might be able to convert an existing circuit and not need new wires in the walls. As long as the circuit is fairly limited (i.e. doesn't go through lots of rooms).

20 Amp 220V IEC

15 AMP 220V IEC

That 15 amp 220 cable is VERY heavy duty. It's 14 gauge. Typically Meridian cables are 16-18.

Your existing power will work fine with the transformer.

What I was referring to was to be aware of where earth potential sat with respect to any mains filters and or grounding. With digital speakers you most likely will be OK. In my case I was using analogue M60 speakers and I believe just used a different earthing arrangement of the various switches on the back of the M60s. You will not have this complication with digital speakers.

Any double insulated pieces of equipment where there is no earth will work without further thought. I may have over thought things, however, I was just careful when it came to equipment that had inbuilt filters and tried to work out if there were any capacitors connected between earth and neutral which would experience a higher voltage across them than they would normally.

Your US supply has the neutral hard connected to earth so you know where you are, in the UK, neutral is nominally at earth potectial but often floats a few volts away from earth. Essentially you just connect your equipment to the two split phase hot supplies to achieve 240v. Any earth would be a safety earth just to ground a metal back box or equivalent.

All my UK Meridian equipment survived 5 years in the US and it is still going strong 12 years later back in the U.K.

Hope the above makes sense, your electrician will be abe to create the correct supply, as you say, it will be the same as you have now for your AC, hob, dryer etc.

John and Fiddler,

Thank you very much guys, that's exactly what I was hoping for.
