0.8 Hp Motor Fla
0.8 hp motor fla is simple with WireGaugeCalc, which reads the NEC full-load current near the listed fractional sizes for your voltage and phase.
You enter the horsepower, voltage, and phase, so the calculator returns the amps used for sizing.
That value feeds the conductor and overload numbers you set next.
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.
Where the 0.8 Hp FLA Comes From
The NEC lists fractional motor sizes like 3/4 hp and 1 hp in Tables 430.248 and 430.250, since 0.8 hp sits between common nameplate values.
The calculator references the nearest listed values so the FLA reflects the standard table figures rather than a raw horsepower-to-amp formula.
Conductor ampacity is then sized at 125% of that FLA because a motor runs as a continuous load.
What the 0.8 Hp Motor Tool Returns
Enter the motor details and read off the values you need:
- FLA at 115V and 230V single phase
- FLA at 200V, 230V, and 460V three phase
- 125% of FLA for conductor ampacity
- A baseline for overload protection sizing
- Amps shown clearly for the next wire choice
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

Why does the NEC table matter for a small motor?
The NEC requires its table full-load current for sizing conductors and short-circuit protection regardless of motor size. Verify the figures against the current NEC and your local authority having jurisdiction.
How is FLA found if 0.8 hp is not in the table?
You reference the nearest listed horsepower values, since the NEC tables list standard fractional sizes. The calculator uses those listed values so your sizing stays code-aligned.
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.
