torque
values.
(2) All torque values are calculated for oil
lubricated threads. Increase this value by 10
percent when threads are not lubricated.

Unit
Function
Differences
.
The engine gener -
ator sets are provided in three configurations accord-
ing to class and mode of operation. The class desig-
nation of a unit is determined by its
frequency
and
voltage performance and the mode designation is
dependent upon the output
frequency
. Table 1-4
provides a quick reference for determining engine
generator
set classification and special component
complement required.

Performance
Characteristics
.
The electrical
performance characteristics for Class 1 and Class 2
sets are provided in tables 1-5 and 1-6.
