I have a dental Lab in Europe an want to move it to the States, maybe. Some of the equipment rates as high as 4kw, and the the total maximum draw is 15 kw for the whole lab. Can I wire a secondary breaker box in a building in the United States that is all 220?
tricky point lookup on to yahoo or google that will can help
You should check all of the equipment to see what is 50hz or 50/60hz (can run on both). Also here in the us we use 230v 3 phase(3 hot legs) for commercial applications. The UK uses 1 phase(1 hot leg) I don't know where you are located.
The first thing to do is examine along with your electricity supplier. You'll have to comprehend if the existing carrier to your residence will control the further load. If it is going to, you must hire a licensed electrician to put in one other panel for you. If this was once my residence i'd have a panel hooked up that will take it as much as eighty% of the existing carrier ability in case you wish to have so as to add extra circuits later. I do a variety of DIY but i'd have this finished by using a licensed pro and get a permit and inspection. That approach, if there may be ever a hearth or electrical damage your insurance company does not have a cop-out excuse to not pay given that the work wasn't accomplished by means of a pro and inspected.
You can get 240V. 60 Hz in 'The States'. Equipment designated 220V. 50/60 hz. will work just fine. Equipment not listed for 60 hz needs to be evaluated on an item by item basis.
Sell it off in Europe and start off with new equipment in the States. All European electrical appliances operate on 50 Hz/cycles when American appliances use 60 Hz. It's not feasible to adapt the change. There is 220V service available here but it's all 60Hz. EDIT: If the equipment is rated for 50/60 Hz you can use it here, you'll have to bring in an electrician to provide the power for it that can produce a stable/clean 220V. Most of the time higher voltage equipment will be rated to perform between 208-230V although having a single-phase power supply for 220V is feasible provided your equipment is indeed single phase. I'd think that what you have for a dental lab wouldn't require three phase power, best to consult with a master electrician before you commit to shipping your stuff stateside to be sure. Good luck.
