So the electrical service is being upgraded in the house to 200Amp.
Three 20A 220V lines are being installed for my SB Heavy 10 lathe and 2 mills, Burke #4 and Van Norman #12. My tiny shop is right next to the main panel.
I agreed to provide the three disconnect switches. They need to be non-fusible.
I am looking at some Cutler Hammer 30A, 240V 2 pole boxes:

Question- there are 2 pole, i.e, they break the two hot wires. What happens to the neutral? Does it go through the box? (unbroken). Should I get a 3-pole switch so that all 3 wires in the 220V cable are broken?
Thanks!
