For disconection times we have to hit 0.4 for up to 230v U0. 0.2 for 400-1000U0.
I always took this to mean what it says.
both single and 3 phase V to earth is 230, so we use the 0.4 disconection.
Taking my 17th update and got told that was a typo!!!!
So for 3 phase we are supposed to use 0.2, single 0.4.
Now that is not what the book says!
So what am I supposed to design my circuits for?!
The question is partially moot as I always use MCBs so they knock off in 0.1, but that is not not the point.
When I chuck in my next 88, what should I desgin it too?
