Hi dear 'ask me' community,

I have a 30KW generator with a automatic transfer switch - it has a three phase input U, V, W and N which
Needs to be connected to the city power it then has an output that goes to the building. How do I know
Which phase of the city supply needs to go to the U, V, W and N (neutral). Can an incorrect phase
Connection cause damage to the generator - how can I avoid this!

Your help will be greatly appreciated!

Thanks - Maruli!
