Here in the usa, the home voltage is 120/240 with a typical panel in a new home being a 200 amp main breaker. What is it in Finland?
also, weather update - Keep in mind my location is Tennessee . . . hang on, I need to look at a map to get the degrees longitude . . . . ok, I got it now: 36 degrees north, ele 551 feet [1680 M] - pretty far south compared to you
Temp is a balmy 29 Degrees F. or - 1.66... C. and no wind
96% humidity and lightly snowing. It is expected to continue until about 2030 hrs local.
7" of snow [17.78 cm] and slightly wet. snowball packability is exceptional, though not deep enough for a fort to be built. [you can see where my priority is here, heh?]
