How do you call this tool and action in english
#21
John if you have only 15A, how do you manage to get enough power for your tools? At 110V it's only 1650W... or do you have more? My vacuum cleaner is 1600W already...
I think you mix the amperage on each plug and the total amperage for the whole residence.
Please check that.

Yes, I'm sure about the 40A as total amperage in Belgium. But we have very strict control over new installations. Old or uncertified installations may have only 20A. I agree this is outrageously high but not that dangerous as long as you have the proper installation.
If fact, 40A is the power between the counter and the circuit breakers box. Each circuit breaker limits current to 20A down the house for power plugs and 16A for lights. Which is still way too much IMO.

But consider that my sister bought a 7kW electric cooker, on 220V it's 32A (in the US you would need 64A...) and we had to pull a specialy large cable up to the kitchen. But we didn't need any special autorisation.
It goes without saying that she is never using even half of that crazy power.

In such case, we can resort to 3-phase (or 3 lines, not sure how you call it in english) which demultiplies voltage and allow for less amperage and stronger devices. 3-phase voltage in Belgium is 380V (you would think it should be 3x220, but no. Because of mystical physics of waves crossing each others and so on, it's 380V).
Now 3-phase current is realy dangerous stuff.
(it just reminds me that I don't know how much 3 phases works here in Lithuania and how the connections must be made. I don't use it anyway)

The danger is increased when you have more amperes than what you need. Then in case of electro shock you get all these amperes through your body...
To avoid that there are circuit breakers with various sensitivity, clamping at very low amperage (300 and 30 mA).
But the real risk is with voltage because the higher the voltage the easier the current will reach your body.

Fred, I'm not an electrician, so I could be wrong about the 'line in' into the house.  After all, that's what really counts. Each separate trip switch is somewhere around 15 amps, maybe 20 amps. And there are quite a few of these in my electrical switch box.

I understand. You must have more than 15 or 20A as a whole.
Oh and you call these circuit breakers trip switch. How sweet... S5

Same thing Fred. Its just that my 72 year old brain couldn't bring up the "circuit breaker" phrase quick enough. S13

Here is your tutorial.

Most USA homes have either 100 or 200 amp service. Increasing from 100 to 200 amps is about 30% more costly.

What Is The Difference Between 100amp 200amp Service?




The breaker box in my house is a 30 space box.  Its like this one right here, so it could be 100A, 125A, 150A, or 200A circuit. I couldn't find the information about it, so it must be on the outer side of the box.

Our boxes look like this:

And they are full of these little things:

So in the US you have at least 100A, it's like us having 50A. That's more enery than us.

John, the total current coming to your house doesn't depends on the box model, shape or color. You must look for the main circuit breaker, the very first device between the very large wires entering your property or your house and the breaker box. It stands usualy right next to the counter. This thing should be able to turn off the power of the whole house at once. It should be written on it how much it is.
