There is a cnc tech here today. He is installing a fused disconnect switch to our machine. The machine is running 208v 3 ph. It takes 45 amp fuses. The tech wants to install a 60 amp 600 v disconnect.
Is this legal? Safe? Proper?
I want him to instead install a 60 amp 300 v disconnect switch that I have on hand.
He doesn't understand voltage (208 vs. 480) and insists this is the correct box because that is what the manufacture sold him. The machine is multi-volt from 208-480.
