If you have a star connected three phase system, where the three phases
join together that is the system neutral. If you are delta connected
there is not one. So you are both right and wrong :-)
Any 3 phase domestic systems have some bastardised form of star
connection. A three storey block of flats I once lived in had one phase
per floor. I lived there essentially rent free for looking after it and
some other things for the landlord :-)
