Do Americans quote large appliance current at 220V or 110V equivalent?

From the EV it seems the former, but in that case I'm horrified at how power-hungry your appliances are.

A typical new oven sold in Europe is 3.6kW, 16A @ 230V.

A new tumble drier is 600W, so about 2.5A at 230V.

There's such a range of hot tub and AC sizes I can't compare these.

240V circuits are simply both legs of the 120V split phase connected together, so the amperage is measured at 120V. The circuit breakers for 120V and 240V circuits are the same, except 240V circuits use two breakers with the handles tied together[1]. Electric resistive heaters like ovens and clothes dryers are always perfectly efficient, so I'm not sure how you even thought it would be possible to have an inefficient heater.

[1]: The 120V rails in the middle of the breaker panel alternate between each split phase, so if you connect a circuit to any two adjacent breakers you will get 240V. A 120V circuit is connected to neutral and a single breaker.

As well as using a heat pump, a more efficient dryer can be better-insulated, or make better use of the heat produced in drying clothes, however that might be done.

They're inefficient relative to a 250-500% efficient heat pump.

Fist, North America is a 120/240V system, not 110/220. For the life of me i will never understand the confusion over why some people, including North Americans keep referencing 110 volts?

The code is clear, 120 Volts +- 5 to 10 percent?

Perhaps because the "allowed range" is 110 to 125? If i measure my house right now, it is 121 volts and this is pretty typical.

Your dryer example seems like it is running on gas?

In North America, electric dryers use anywhere from 1800 to 5000 watts.

AC depends on the home size, the location, etc. Mine has a 60A 240V breaker but again the "code" states you can only have an 80% "continuous load" on a circuit so technically this circuit can not pull 14,400 continuous watts.

One thing Europeans dont grasp is the difference in house sizes vs north ameria and so naturally our appliances are larger and more power hungry.

What may take a European washer 2 loads, most north american washer/dryers will do in one. So the "power usage by load" is the same?

Using a device like a range's maximum power draw is dishonest. If a north american range is twice the size of what is available in EU, but not all the elements are in use at once... does that mean something?

(110V: I'm just copying/misremembering, I don't live there. There are places in the Caribbean that do use 110V.)

This is part of my horror. You can't imagine that an electric drier might only use 600W? Try [1]. From the EU site of all rated driers [2] (click "Models distribution") 23% of driers on sale are this efficient. A further 44% with A++ rating are around 900W. (Note the measurement is of the energy needed to dry a load of clothes to the required standard, the maximum power draw is related but not a criteria.) The worst one is still only 2300W!

From a 2013 news article "Europe's Clothes Dryers Consume Half As Much Energy As America's" [3]:

> The study, which was funded by the Super Efficient Dryer Initiative (SEDI), concluded that Europe's heat pump dryers can dry the same amount of clothes as North American conventional dryers using only about half as much energy. The catch is that European heat pump dryers also took about twice as long to dry a load of laundry as North American conventional dryers.

I'll add that American driers appear to be cheaper to buy.

> house sizes ... naturally our appliances are larger and more power hungry

That explains the AC -- though I can still criticise the waste of energy heating/cooling two, three or four times as much space per person -- but it doesn't explain the drier. Do you wear twice as many clothes as I do?

My small, or at least unremarkable, oven is 4.8kW, also 230V. It's from about 2006, iirc.

Electric tumble dryer is 5.6kW at 230V. It's from 2017. Maybe yours is gas, and 600W is the motor?

I have a smallish 1900sqft 1950s house with average or smaller appliances.

I love doing appliance comparison with European houses, though.

New heat pump tumble dryer, 600W: https://www.siemens-home.bsh-group.com/uk/productlist/laundr...

New condensor tumble dryer, 2600W: https://www.siemens-home.bsh-group.com/uk/productlist/laundr...

My dryer is 8 years old and similar to the second one -- half the power of yours, and I'm still not sure what the 24A from above would mean.

Almost all big appliances are 220. Fridges are 110, but the big guys

* EV Charging

* Electric or Induction Oven

* Electric Dryer

* AC

* Electric Water Heater

are all doing to be 220. The amps will vary, and most will not peg the required wire 100%, but may for example do a big pulse to startup (ACs are famous for this).

[kennend3]

For which country is this?

Only a handful of countries actually us 110/220

If it is North America, I think you mean 120 and 240
