Equipment & SystemsQuestion 349 of 521
What marking must a generator carry?
a.A nameplate giving the maker, rated frequency, power factor, kW or kVA, voltage, and rating such as continuous or standby
b.No marking is required
c.Only the serial number
d.Only the fuel type
Explanation
Section 445.11 requires each generator to have a nameplate giving the manufacturer, rated frequency, number of phases, subtransient and transient impedances, power factor, rating in kW or kVA, normal volts and amperes, and the rating (such as continuous, standby, or prime). A serial number or fuel-type marking alone would not satisfy this requirement.
