find the line current first...

i=(150*735.5) / (sqrt(3)*600*0.8)

assume pf of 0.8

the current value gines u reqd fuse rating

What should be the minimum insulation value of a 20 kw 415v phase motor?

415V commonly available wire is 300V or 600V so that would need to be 600V wire to use a megger or a hipot tester (2* operating voltage +1000V) 2000 volt megger or hipot should verify the wiring in this instance 2500v megger will be necessary for 600V wire and wiring devices you also must look and ambient temperature and humidity a test after some operation time can verify this
