We have a large parking area for refrigerated tractor trailers. Each parking spot has a power cabinet with a 60 amp 3phase 240volt outlet. The drivers plug the trailer in to site power for the trailer refer unit. The question is; does the NEC require the 60 amp outlet to be ground fault protected. I have searched and cannot find a reference to other than 15 and 20 amp circuits.

No, you could choose to but if you do I strongly recommend temperature monitoring of the trailers.
