    NEMA Motor Data Calculator


This spreadsheets can make calculations for the following:

First : motors data

For single phase motor:
1-select the horse power rating
2- you will get the results for 115V and for 230V single phase voltage, the results will be as follows:

  • Full Load Amps (FLA)
  • Wire Size
  • Thermal Breaker Size
  • Breaker Cat No.
  • HD Switch Nema 1 Enclosed
  • Dual Elem Time Delay Fuse Amps
  • Fractional HP N1 Starter Class 2510
  • Thermal Unit
  • Integral Starter N1 Enc 2510
  • One Melting Alloy Thermal Unit
  • NEMA Enclosed Starter Class 8536
  • Thermal Unit

For three phase motor:
1-select the voltage
2- select the horse power rating
3-you will get the following results:

  • Full Load Amps (FLA)
  • Wire Size
  • Thermal Breaker Size
  • Breaker Cat No.
  • HD Switch Nema 1 Enclosed
  • Dual Elem Time Delay Fuse Amps
  • Nema Starter Catalog Number
  • Melting Alloy Thermal Unit
  • Nema Size Starter


Second: Transformer Data

1-Enter the KVA and Voltage
2-get three-phase and single-phase currents




Third: wire and conduit data
1-select the wire size
2- get the conduit size for different circuit configurations for both copper and aluminum wires

Forth : voltage drop data
1-Select wire size as before.
2- Enter the cable run distance in multiples of 100 ft.
3- Enter the amperage you will be drawing through the wire.
4- View the voltage drop for single and three phase based on PF.
