If the system voltage is between 150 V and 300 V, then either double insulation or a separate safety ground with the same gauge wire as the hot conductor is required; the purpose of the safety ground is to keep the equipment case or cabinet from reaching 150 V in case of a fault.
In this case a Class C GFCI may be used to provide fibrillation protection, let-go-protection is optional.
A Class C GFCI is 20mA trip current.
This will not spuriously trip your freezer. If you're having issues with this it's because you're designing your power distribution system incorrectly.
