What is the proper type flex to flex in a 4160v motor? The flex being used is liquidtight nonmetallic, but didn't think this was correct. I could not find answer in the code book.

Take a look at 356.12(4). LFNC is not allowed where the operating voltage of the contained conductors is in excess of 600 volts, nominal, except as permitted in 600.32(A). 600.32(A) pertains to neon lighting.
Liquidtite Flexible Metal Conduit is allowed and is what we typically use. Flexible Metal Conduit is also allowed as long as the install isn't prohibited by 348.12.
