ambient (surrounding) temperature in which the
motor is designed to operate. This temperature
is shown in Celsius rather than Fahre n h e i t .
1 4 .INSUL CLASS (Insulation Classification):

1 6 .CODE: The NEMA code letter specifies locked
rotor kVA per Hp (volts multiplied by locked rotor
amps, divided by 1000 times rated HP).
1 7 .S E R I A L : The serial indicates the date of
m a n u f a c t u re, which often appears as year/month
combinations. Serial code information for each
