Or commercial/industrial, by the looks of it.well i have just qualified as an electrician,but havent had enough experience in domestic wiring
Not going to make a huge difference though is it!
Atleast it is not tens of amps out which it would be if you had originally designed the circuit
He is a qualified electrician tho...
that's the problem with using 230 and 400 though..
230 x sqrt3 = 398.37V..
so depending on the method you use you get a different answer..
power / (3 x Vphase ) = 18500 / (3x230) = 26.81A..
power / (sqrt3 x Vline ) = 18500/ (sqrt3 x 400 ) = 26.70A..
Would your customer be happy to know you have to resort to asking these questions on a forum?
Is that what they pay you for?
i am only enquirying i aint planning on doing anything
You are a danger to your customers and should not be doing this work.
I know you just want a simple answer, but that is not going to happen.
You are installing electrical circuits for a living, so the least you could do is actually make the effort to learn how to properly design and install circuits your self, rather than just guessing at it like you do now.
