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...
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.
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.

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

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.

The information you seek is all public record and the standards have been standard for decades, do your own homework.

In the UK regular wall sockets that you can find in every room are 230v x 13A = 2990w max

There are some higher amp ones but they are usually only found in the kitchen for cookers.

By the way it's the Amps that kill you, not the Volts, America got it wrong, crony capitalism won out over science fact!

Wrong a 50v capacitor will kill you with very little amps.

3120w   240v x 13a  voltage at the wall here in the uk is 240-250v  

dont forget to acount for the powerfactor 2000w at a pf of 0.5 will be double the amps of a pf of 1

i  would re prase that to could kill you ( i have had a few 6kv plus shocks of capasator banks ) ac electric is more likly to kill you than dc electric

Amps AND Volts.  Not one or the other.

My house (UK) has  ~240v @ 100A.  Three phase is common in industrial buildings.

its the amps that kill but due to ristance it needs the volts to get there

As we export electricity to Europe we have to too keep it around the 230v mark although you should
design any device to expect 5% variance either side because we actually switch on/off hydro power
stations to level out the power fluctuations!  There is actually a man who watches the power demands
and phone calls another man to turn the thing on! That's really how it's done here!

Which country is that?  The UK uses hydro to the same effect.  Usually in keeping with the TV schedules, as everyone switches on the kettle when a popular TV program ends.

Remember, don't try running 15A from a 15A circuit. You need to limit the draw to around 20% less than the rated amount. This is for safety to prevent a fire.

The answer is simple, 15A(really 12A) as that is the most common circuit type in the U.S.

A 50v capacitor doesn't even have enough voltage to overcome the resistance of your body. So no, it won't.  A 100v+ capacitor on the other hand can.

[Isokivi]

Running of 10A fuses would be ideal as it would allow one to max out the sockets around here. 15A is also available, but the more the merryer and so forth.

Who cares which is important.  A 220V circuit has plenty of each.    V=IR

How will your asic use 1800(!)watts? Also, if you're serious, you could hook up mining units to 240v outlets (the ones used for dryers).

Or maybe, don't fucking touch the outlet?

[Ytterbium]

How many amps you get is going to be limited by your own body's resistance, and by the voltage imput.  More volts = more amps at the same resistance, so a higher voltage is going to be more dangerous for people.

[iikun]

Having been zapped several times & once quite nastily on 240v circuits I can testify that it definitely does not tickle!  Whoever said what doesn't kill you can only make you stronger, I'd like to electrocute that bastard lol

In any case, this is a discussion about how much can be safely drawn from the wall rather than who's voltage is more dangerous to prying fingers. Here in Japan homes rarely go about 15A so even 20A would be a serious problem unless you have access to commercial premises.

This is a serious question. Do not seek an answer from random folks on the Internet. Look up actual standards for countries that interest you.
