Over here the standard household max Amps is 13A = 3120w.

It's funny I have always thought it was 240v but they claim its 230v but when you measure it it is always 240v,
The wall sockets have a lever that when the Earth pin goes In it then opens the Holes for the Live and the Neutral pins on the plug, plus you can change the fuses on the plug, which range from 1A, 3A, 5A, 7 or 8A, 10A and 13A

It depends on how many amps the outlets are. Most standard household outlets are 15 - 30 amps. I always made mine out of minimum 12/3. To be totally safe then 10/3 is a better choice. The cord I described is very useful and served me well when I was in the temporary power industry in the 90's. We used them mostly for daisy chaining GFI boxes from small 25KW generators that were pulling light loads at construction sites.
In the spirit of Expedition Portal and its user base this cord is more useful for someone who has a rig that needs to be plugged into a 208 single phase source that may not be available.
Again the key is to make sure it's plugged into to separate circuits. And that is very simple to check. After plugging into the receptacles measure across the hots at the female end. If the voltage is 0 then it's on the same circuit. 240 or so then you are good to go.

We always said 208 to indicate a single phase circuit. In reality it's about 240. Temporary power and generator service speak....

My RV has 30 amp service. I have a plug that reduces the 30 amp plug to 15 amps.
I can plug into any standard plug with it. That allows me to use my AC when I am at a relatives house.
I can also use the fridge on electric without blowing the breaker. Try and use the microwave and it pops.

Academically speaking, AC voltage rating partly comes down to how you measure it. For AC power, there are different methods for rating the voltage of the sine wave: Peak-to-Peak, Root-Mean-Square, Average Voltage, etc.
Which gets used depends mostly on who you are talking to and what that person plans to do with the energy. An electrical engineer, who is likely to care about power, will probably use RMS voltage, as that more accurately captures the area under the curve. (This is the value most directly analogous to a DC voltage.)

Couple the different methods with the real-world variability of power delivery at a distance, and the number could be +/- 30% or more.

And if you really want to mess things up try using North American 60 HZ frequencies on delicate audio and video equipment. When I was in the generator industry we had to adjust our HZ on the generators to accommodate foreign performers equipment. It was a very difficult process to get it just right to avoid feedback and buzz.

I disagree. Makes no difference how much power you connect to. Your unit should have a main breaker and sub circuit breakers protecting the truck and appliances. Which is exactly how homes work too.
On the other end, if the power supply is 15amp and you are drawing 30amps. That 15amp service supply breaker will give you a black out.
