South Korean standard receptacles in the US

I think the cord adapter would be the way to go. Install 120/240 combo receptacles everywhere, maybe in quad double gangs and then they can use American and whatever else they want.1000005778.jpg
 
Many companies make the Shuko 22.5mmX45mm to single gang adapter plates;
international configurations inc is based in the US and makes them;

MOUNTING FRAME FOR AMERICAN 2X4 WALL BOXES. ACCEPTS ONE 45mmx45mm OR TWO 22.5mmx45mm SIZE MODULAR DEVICES. MOUNTS MODULAR OUTLETS, SWITCHES, RCBO (GFCI), RCBO (OVERLOAD) CIRCUIT BREAKERS ON AMERICAN 2x4 WALL BOXES.

Order a few of those and put any international plug you want in your office.

What exactly is the equipment they will be using? Computers and other office electronic equipment won't care.

Good point. Almost every PC or laptop power supply I see now has a wide input of something like 100-250VAC, 50/60Hz. Then they have a universal IEC “C-14” inlet that allows you to just change the cord to whatever there is at your location.

A South Korean company is constructing office space for their staff in New York City. They are bringing equipment with South Korean electrical plugs rated for 220V. The frequency in South Korea is 60Hz. They have requested that we install numerous South Korean standard receptacles throughout the space. I am considering installing an autotransformer to convert from 208V to 220V and a distribution panel.



The main questions I am considering are:



1. Is it legal to install South Korean standard receptacles in the US?

2. Is it legal for the tenant to use South Korean equipment that is probably not tested and listed by US laboratories?



Based on my research, the answers to both questions above are negative.

Did you determine which South Korean company did their UL-equivalent testing? Is that testing company a NRTL in the US (could happen)?

It's for hotels for phone chargers I think.

But the instructions specifically call out one of the terminals as neutral. Are hotels providing a separately derived 240 volt system with one conductor grounded? I know the devices plugged in probably won't care either way, but code requires us to follow manufacturer's instructions.

No its just if you do connect it to a 416Y/240 system you consistently use the same pin as neutral.
A real Shuko even if not UL listed provides better protection than that plug and meets the 'equivalent' intent in 90.4, I would consider those Leviton plugs on a 240V 15A circuit a violation of NEC and IEC as a 120V cord cap fits.
