The neutral line is separated with single phase power line.How can used the supply line to the Instrument. Please send the details with circuit diagram and details spares.

2... 240... 60 amp breakers
If you have 4 circuits of 60 Amps you have 4 breakers of 60 amps = total of 240 Amps.
Than what does the 2 indicates?
Double circuits of 4 circuits of 60 Amps = 2 x 240 Amps ? Why?
If not : 2 x what than? It makes no sense to me!
.
And as stated before : 60 Amps means 4" wire. Phase and neutral. Don't forget earth.
.
And what do you still want to know, additional to what you were told earlier?
