Because the various power systems world-wide do not match the power system in the United States there are two main ways of preparing equipment for use in the United States. Either means may be expensive and cumbersome to implement.
In the United States the power system is 480 volts - 208 volts 3 phase / 120 volt phase to neutral. In Europe and Asia the power system is 380 volts 3 phase / 220 volts to neutral.
Because of this difference the first method of preparation would be to modify products and equipment to match the power supply that is used in the United States. This would include any motors and controllers on the equipment.
Equipment to consider renting in the United States would be lighting and food service equipment provided it is not part of the equipment produced by the client.
The second means of preparing for equipment manufactured in other counties is to rent a 480 volt to 380 volt – 220 volt European type transformer. The cost for the transformer is dependent on the amount of amperage required to run the equipment; the minimum allowed is 20 amps at 480 volts; plus the cost of renting the transformer. Additional costs that may be required; Labor, hoist equipment and the cost of running the cable from the power panel to the transformer and then to the equipment. The transformer is typically placed within the booth space and will require a five foot square space (1.5 meter by 1.5 meter)
