The "amp- 33" part of your query could mean a few different things: Amperage Rating : A specific current rating of for a generator or motor. Standard Reference : A shorthand for NEMA MG 1 Part 33 , which covers definite-purpose synchronous generators. Section 32.33 Standard Reference : A shorthand for NEMA MG
Specifies the allowable heat levels during operation to prevent insulation failure.
