Motor Ampacity (FLA)(FLC) and
Characteristics |
 |
|
|
|
|
| |
Volts' Motor Ampacity and
Characteristics module uses either NEC®
Tables 430.247, 430.248, 430.249 and 430.250 OR known motor nameplate
values for its computations. |

When entering data from the NEC®
Motor Ampacity Tables: |
| |
Volts
interpolates the power value to the correct amperage if an exact
match is not found in these tables. For example, a 7 1/2 hp
inductive motor is rated at 22 amperes at 220 volts. What about
an 8 hp motor? Volts' interpolation algorithm makes it easy.
Volts calculates amperage values either above or below the NEC®
tables and displays the results. |

|
| |
When entering data from the known motor nameplate values: |
| |
Volts
utilizes your entered nameplate values and computes the motor's
required ampacity. |
| |
|
| |
This module computes: |
| |
- The motor's full load amperes (FLA or FLC)
- Required overload (primary) protection
- Required overcurrent (secondary)
protection
- Locked rotor amperes (LRA)
- NEMA starter size
- Reactive power in kVARs
