Wire size for control panel

We are about to run wire for some preassembled control panels for a motor and pump we are confused. The motor is a 10 hp, 480 volt. Which would only be 14 amps. However the control panel has a sticker on the front saying the motor is 2 amps. It also calls for 60 amps even though the control circuit is only 5 amps. Where are they getting these numbers from? How do I determine my wire size?


Here are some pictures of the motor name plate and the sticker on the panel
 
I would have the manufacturer clarify and ship out a new nameplate because that thing is obviously not it lol.

That UL# doesn't look right to me. They usually start with an "E".
 
If there was only one motor or one ten HP motor bring able to run at a time the 60 Amps is way too high. A conventional plain Jane NEMA frame two or four pole motor only draws between 12.5 & 13.5 amps. That one states 14 amps. I have installed 10 HP 480 vo!t three phase motors on 20 amp quality time delay fuses using 12 gauge copper THWN wire. Control circuit almost always are supplied by a 480 to 120 volt transformer. Even with the control transformer a 30 amp circuit should be able to supply power.
