PART 1
GENERAL
**************************************************************************
NOTE: This section covers motors with special
features of construction which are considered
necessary to provide maximum insurance against
failures where the motors are to be operated only
for short periods of time, at infrequent intervals,
and at locations where the average relative humidity
of the air is high. Where operating characteristics
or features of motor construction differ from this
specification but are considered desirable, this
specification may be modified accordingly. The
designer must also consider unusual service
conditions such as direct exposure to the sun,
vermin infestation, or high altitude.
