Folding Forum

More easily powered on a European residential circuit using 220 V. In the US a 15 A, 220 V connection and have two power supplies on opposite legs of the circuit. Some homes would have that available, it was a fairly common circuit for a larger window air conditioner.

If you're springing for that board, a case for it, 16 GPU cards, the cost of having a 110V/30A outlet installed is small change. Alternately, converting an existing 220V outlet into two 110V outlets would probably be even smaller change.

Jep, in Europe, that's less a problem. The standard circuit has 230V, most Plugs (Schuko) are specified with 16A. Here in Switzerland, the plug is specified with 10A. And most homes have a 400V (3 times 230V phases with 16A) plug, mostly for the dishwasher or washing machine / tumbler.

13amp 240volt here in the UK, that will even power a tumble drier/dishawasher

In the 80ies all dishwasher / tumbler / washing machine had rotary current with 400V. All of those machines had them in our house and so we still have those sockets. That changed in the last 10 years to 10A 230V.

Here in the US, the standard dryer circuit is 220V/30A. Split, that would yield two 110V/30A circuits...power is power and watts is watts.

We don't put 3-phase outlets in homes here in the USA. That's just for industrial equipment.

It's either 120v(2 wire + G) or 240v (3-wire + G) single phase.

Same in the UK.

Getting 3 phase installed is a pain. It's only really used for industrial purposes.

When you consider having 3 phase installed in your home so you can run folding, you have more problems than power. :/

here in Japan is 110V-power lines are weak ... at least in the house I'm in ... I wish I could load more without burning down the house. Sometimes I wish myself back to the good ol' german 220V

i thought Japan had a 100v standard rather than being "weak"

From my understanding Japan has two standards depending on location. Both are 100 V, but eastern regions have 50 Hz supplies and western regions are 60 Hz. 200 V circuits are generally available to handle higher wattage equipment.

Also, many older Japanese houses had only 10-30 amps at 100V for the entire house!

Once I opened a plug in the wall and watched direct on wood ... no casing for the plug. And often enough I see little sparks when connect/disconnect. Sparks, wood, ... I wish more German TÜV would be around ...

In my house (which is not big and use 30 year-old norms), I have main 500mA differential circuit breaker calibrated for 30A (which is what I pay for), then I have two 10A circuits for the lights, three 16A circuits for the electric plugs, one 20A circuit for a very old plug that was used for old washing machine and one 32A circuit for the kitchen (oven, dishwasher and now unused hotplate).

Here in France, we use 230V/50Hz and I use city gaz (and computers lol) to heat the house.

In a more modern house, you'll find one or more 30mA differential circuit breaker (40A) between the main one and the fuses for the circuits. And the fuses would be replaced by circuit breakers.

We have a small house here in the US. 200amp/220V main breaker, 30amp/220V for the dryer, 20amp/220V for the well pump, 30A/220V to supply power to the outbuildings, 20amp/220V for the air conditioner and the other 32 slots in the panel are a mix of 15amp/110V and 20amp/120V to feed the outlets (20 amp circuits in the kitchen and basement and 15 amp for the rest of the rooms). Each room is fed by two circuits so it's kind of hard to overload anything. The kitchen, bathrooms, basement and exterior outlets are GFI, ground fault interrupter for additional safety.
