2hp Motor Flc
2hp motor flc is fast with WireGaugeCalc, which returns the NEC full-load current for a 2 horsepower motor.
You set the voltage and pick single or three phase, and the tool reads the matching motor table value.
So you have the full-load current ready for conductor and overload sizing.
Open the calculatorEnter any two values and read the rest.
Ohm’s law: V = I × R and P = V × I. Field aid only, verify against the current NEC and your local authority having jurisdiction.
Reading The Full-Load Current For A 2 Hp Motor
Motor sizing uses the NEC full-load current tables, since 430.6 directs you to those values rather than the nameplate for conductors and devices.
A 2 hp single phase motor draws about 24 amps at 115 volts and about 12 amps at 230 volts, while three phase versions draw less for the same power.
The tool reads the right table row so the FLC fits the voltage and phase you actually have.
What The FLC Drives On A 2 Hp Circuit
The full-load current sets the rest of the motor circuit:
- Conductor size at 125 percent of FLC for a continuous motor
- Overload protection sized from the nameplate amps
- Branch circuit protection sized from FLC and the device type
- Voltage choice, since 230 volts halves the current of 115 volts
- Phase, because three phase draws less current per leg
One app for every NEC calculation
WireGaugeCalc keeps the calculations you reach for most in one place:
- Voltage drop and wire sizing for any run
- Conduit fill for EMT, PVC, and RMC
- Box fill and junction box sizing
- Ampacity and temperature derating
- Motor circuit and load calculations
- Conduit bend offsets and saddles
Built for the field, works offline
The whole app runs on your phone, so it keeps working in a basement, an attic, or a job site with no signal.
There is no account to create and nothing to load. Open it, run the number, and get back to work.
- No signup and no signal needed
- Answers in a tap, not a spreadsheet
- Same tool on phone, tablet, and desktop
Every result cites the NEC article
Each answer shows the table or formula it came from, so you can check the method and learn the code as you go.
That makes the app useful on the job and during exam prep, since the reasoning is right next to the number.
Switch the code year your job runs on
Jurisdictions adopt the NEC at different times, so you can match the calculation to the code in force:
- NEC 2017, 2020, and 2023 tables
- Copper and aluminum conductors
- 60, 75, and 90 degree C terminations
- Single-phase and three-phase systems
Run the number, then get back to work

Open the calculatorFrequently asked questions
What is the FLC of a 2 hp single phase motor?
The NEC table lists about 24 amps at 115 volts and 12 amps at 230 volts. Verify the table value against the current NEC and your local authority having jurisdiction for your install.
Should I size the wire from the table FLC or the nameplate?
Size conductors and branch circuit protection from the table full-load current, and size the overload from the nameplate, as NEC 430.6 directs.
Is WireGaugeCalc free to use?
Yes. Every calculator is free to run with no signup. A paid tier adds saved projects, PDF reports, and extra code years, but the core math stays free.
Does it work without internet?
Yes. The app runs on your device, so it keeps working with no signal on a job site, in a basement, or in an attic.
Are the results code accurate?
Results follow published NEC tables and standard formulas, and each answer shows the article it came from. It is a field aid, not a stamp of approval, so verify against the current code and your local authority before you wire anything.
Which NEC code year does it use?
You can switch between NEC 2017, 2020, and 2023, since jurisdictions adopt the code at different times. Pick the year your job runs on.
