    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.
