Adiabatic equation

[Mattdev]

This one has always made me wonder !??
Does this work as simply for a 3 phase installation i.e 3.3kw over 230volts = 14.3 amps
so does 3.3kw over 400volts = 8.8amps per phase OR is it 3.3kw over 230volts divided by 3 = 4.8 amps per phase ???

Hello.

It will be Ib / square root of 3 x Ul

which will mean

3300 / (1.732... x 400) = 4.76 Amps

a factor may also need to be considered.
