The standard electrical system in use at most convention facilities in the U.S. is 120/208-volt three-phase with a neutral and 480-volt three phase. Most countries outside the U.S. use a different voltage and plug configuration from the US. To use anything that requires electricity that is made for use outside the U.S., you must take both the voltage and the plug configuration into account. 208-volt three-phase connections are not intended to be used with ANY international power needs and should never be ordered without calling the phone number provided on our order form or calling 1-800-553-3536 for more information.

Equipment Power

Most 220-volt equipment will operate at 208-volts. Almost all 230 and 240-volt equipment and some sensitive 220-volt equipment will not operate properly at 208-volts and will require a transformer to boost the voltage to approximately 230-volts.

Determine the amount of power each piece of equipment requires by looking at its rating stamp. This stamp can be found on the back or bottom of most equipment, but sometimes, manufacturers choose to make it more difficult to find. For example; you may have to look at the transformer plugged into your laptop to find its rating. For objects such as refrigerators and microwaves, the rating can be found inside the door.

The ratings placed on the equipment will indicate VOLTAGE, AMPERAGE and PHASING. All three ratings are required in order to order the correct service.

Example rating stamp for small European Electronic Equipment
100-240V~ 1.6A 50-60Hz*

This rating indicates the equipment runs on 1.6 amps with a range of 100 to 240 volt single-phase a.c. (~) power. This can be powered by ordering either a 5A 208 volt single phase connection or ordering a 500W 120V outlet and using an adapter to the standard US outlet.

Example rating stamp for European Coffee Maker
1200W 220-240 Volts 50Hz*

This rating indicates the equipment runs on 1200 watts with a range of 220 to 240-volt single-phase power. To convert 1200 watts to amps, divide 1200 (the wattage) by 200 (the voltage) = 6 amps 208-volt single-phase.

Example rating stamp for small European Machinery
240V 15A 50Hz*

This rating indicates the equipment runs on 20 amps of 240-volt single-phase power. Because the voltage is over 220-volts, you will need to order a transformer to boost the voltage to approximately 230-volts.

Example rating stamp for large European Machinery
26A 220-240V 3PH 50Hz*

This rating indicates the equipment runs on 30 amps with a range of 220/380 to 240/415-volt three-phase power. 208-volt three phase will NOT work for this application. If your equipment requires 380-volt thru 480-volt power, please contact the phone number provided on our order form or call 800-553-3536 for more information. Exhibitor’s requiring 380-volt power must contact the Edlen office producing the event for additional order information.

*Note regarding 50Hz. Most equipment for use outside the U.S. is designed for use at 50Hz or 50 hertz. The U.S. electrical system is 60Hz and almost all 50Hz equipment operates at 60Hz. Please check with an engineer who is familiar with the equipment to determine if your 50Hz equipment will operate at 60Hz.
