It is not necessary to change anything on the electrical supply grid.. The mains are everywhere 3 X 380/400V+N. therefor in between each phase and N you obtain 220/240V. ( almost everywhere in the world ). However it would be virtually impossible ( due to cost ) to convert the USA system... 110V... May sound like unnecessary but bare in mind Ohms Law.  

Different frequency too.....

Yes, I didn't mention that, but now you do , 50/60Hz.

And I also didn't mention: W ( watt )/V (volt )=A ( amps ). Where this is important is that( in the  USA vs the rest of the world ), due to lower Voltage the Amperage goes up. This again being important because the Heat induction is not Linear but logarythmic.

Everyone follow??????

Earlier this year i ran across Second Road from  Mikes shopping Mall to Kiss & food Restaurant, outside that  Restaurant is an eEectric post  which i grabbed  to slow myself from running, and  received an Electric shock from that post, Waitress in that Restaurant said many people complain about it ... ( but noting done)

That is in order to reduce your heart beats rate after all the running..????

My apologies to the ones reading this. Yesterday I used the term ' logarythmic ' whereas it should say : ' Exponential ' . Experiencing some IT problems for the moment, my brain was confused....

Be careful here, hospitals are a special case. They usually have completely different electrical systems due to the nature of the site and the medical equipment used. Flammable gases, oxygen, explosive situations, complex medical imaging equipment. This is a very specialised area of electrical engineering.

 

 

 

 

 

Most hospitals have the same electrical voltage throughout.

It doesn't matter, the underlying ground system is usually different, often an IT ground (Isolé-Terre, not Information Technology) where the transformer is intentionally isolated from the ground rather than bonded to it. The voltage is irrelevant to that. As I said, it's complicated.

 

The reason for this is you don't want breakers tripping power during surgery, and you don't want ground loop noise on diagnostic equipment, all kinds of issues in hospital environments.

It mattered to me when one of the transformers we had to use to convert 110v to 240v fell on my foot. Rather heavy, it was.

How about PPE ????

Could you step-up after?
