The benefit from the FLA correction is the possible use
of smaller power wiring and/or starter size.
The locked rotor amperes (LRA) are read directly from
Tables 3 and 4 for specific Motor Code and voltage. This
is because the LRA is dependent only on motor size and
voltage and is independent of input power (kW).
Inrush amperes (IRA) depend on LRA and the type of
starter applied. The inrush can be calculated using a
percentage of LRA shown in Table 5.
