115v 11amp 700 Feet Of Wire Size
115v 11amp 700 feet of wire size is fast with WireGaugeCalc, since you enter 115 volts, 11 amps, and the 700 foot run and the tool returns a conductor size.
The calculator checks the NEC 310.16 ampacity for your conductor material and termination temperature, then it measures voltage drop over the full distance.
You get a gauge that carries the load and keeps the drop in check before you pull a single foot of wire.

Why 700 Feet Pushes The Gauge Up
An 11 amp load only needs a small conductor for ampacity, so a long run is what really decides the size.
Resistance adds up over 700 feet, so voltage drop grows as the run gets longer.
WireGaugeCalc upsizes the conductor until the drop on 115 volts stays inside the 3% branch-circuit guideline.
What The Wire Size Result Covers
The calculator weighs both ampacity and distance for this run:
- NEC 310.16 ampacity at 60, 75, or 90 degree C terminations
- Copper or aluminum conductor selection
- Voltage drop checked against the 3% target on 115 volts
- One-way run length of 700 feet entered directly
- An 11 amp load value you can adjust for similar circuits
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
Does ampacity or voltage drop set the wire size at 700 feet?
Voltage drop usually wins on a run this long, since 11 amps needs only a small conductor for ampacity. The calculator sizes up the gauge so the drop on 115 volts stays near 3 percent.
Should I use copper or aluminum for this run?
Copper has lower resistance per foot, so it often gives a smaller gauge over 700 feet, while aluminum costs less but needs a larger size. Verify the final size and termination listing against the current NEC and your local authority having jurisdiction.
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.
