I would not be interested in 30A+ because I would need to run a new circuit to the rack at my data center and it would cost money.
20A would be best for running a large operation for me.

I am doing power and cooling system fitting into 4U rack, I want to make sure that people are not left with only choice to buy something that they can't power because it uses more power than their outlets can support.

Germany: 3 x 230V / 63A house entry point. Typically the last breakers are 230V / 16A or 3-phase 32A.

230V * 16A = 3,680W ~ 2*1,800=120V/15A - that works great

You can get double the performance in one case

What should power limit be on a mining equipment in your country?
Please name the country and list Volts/Amps

In USA many people are limited to 120V/15A while you can get 20A circuits in some places.

Decision is ether to make miner fit into 120V/15A or 120V/20A and then if mined is rated for 15A you don't use 5A on 20A circuit or if miner rated for 20A you have to set it to lower performance on 15A circuit and loose 25% performance. Which one is better?
Obviously miner can use multiple 15A circuits to get better density.

I think if someone has enough technical knowledge and expertise to buy some device, getting a 20A circuit is not an issue... but 15A should make it a bit more "universal" within US. maybe some apartments can't be easily retrofitted with a 20A circuit...

however, power efficiency and draw is a whole other conversation to have once you get into 240V and 30+Amp circuits... but I don't real;ly care about that in my situation.
