I think the point was to protect the machine by bringing it down from a 40 amp. Plus I think this machine would pull more than 8 amps. More like 15-20 amps (being commercial) Then if there was a problem the breaker might trip before some major damage was realized. I don't think you would have to worry about the wiring though. Probably wouldn't even get warm...
My reasoning for the sub panel would be so you could run the grinder and or other appliances off the same feed with their own breakers.
