what will be the motor terminal box connection arrangement
(star or delta). on what basis it decided?

Answer Posted / sasi karthick a

it is standard 6 terminal with 3Starting and 3ending points
of windings. Plz refer the below link for connection
diagram.

for low voltage motors,
Upto 2HP/1.5kW - star
above 2HP/1.5kW - Delta

With the same winding, power of the motor varies 3:1 ratio
in Delta to star.
