THe direction of 3 phase induction motor can be reversed by
interchanging the connections i.e. if motor is connected to
3 phase as RYB now by connecting motor in RBY will result
in reversal of direction of motor as the direction of flux
is reversed by changing the connections

if any house we instaled a 1.5 ton ac and its phase cable of wiring is installed but netrual cable of wiring not instaed. my question is that is neutual of house(for other wiring is capable for ac load or a sepeart neutrual wiring required
