Prime Rating generators are the one intended to run without any restriction of running hour. Output of these generators can be of varying load to a peak demand of 100% for an unlimited time. A 10% of overload capability is allowed for emergency use for a maximum of 1 hour in 12 hours.
Standby Rating generators are the ones for supplying emergency power for the duration of normal power interruption. No sustained overload capability is permitted for this rating.
The size of a generator is related to load type (inductive, resistive, liner, non-linear etc.), loading steps or sequences, application (Prime, standby, continuous) and operation location ambient conditions.
