Do you by chance mean rated for 40 amps?

Yes, I just put two in a kitchen...

 

Up to 60A, it seems

I was told that we need a outlet capable of holding 40 amps for our IT room I just want to make sure something like this exist before I ask the electrician and look dumb...on a 110V

 

You should ask the person with the requirement (an equipment vendor?) to communicate directly with your contractor, or to give you a written spec for the circuit and the receptacle.

 

Another design constraint may be
". . .repeated plug/unplug cycles,. . ."

BTW, IMHO, 'rated for' or 'passing' or 'conducting' is more appropriate than 'holding'.

 

I was told it has to be a regular duplex outlet, capable of handling 40 Amps.

 

No such thing

 

It's probably an L5-30 30 amp twist lock big UPS use them.

 

So my next question is what is the highest Amp breaker that can be used on a duplex outlet that is running on 12-2 wire? There is a 20 Amp breaker on there now and the IT guy thinks it's as simple as swapping the 20 Amp breaker for a 40 Amp breaker. I disagree. Help?
