By downloading or using Solar Wire Calculator ("the App"), you agree to these terms. If you don't agree, don't use the App.
Solar Wire Calculator provides wire sizing estimates based on NEC 2023 tables for solar, residential, marine, and industrial applications. All calculations run locally on your device.
Results are approximations and may not account for all installation conditions. Always verify conductor sizing with applicable NEC articles, local code amendments, and your authority having jurisdiction (AHJ). This app is not a substitute for professional engineering judgment. Consult a licensed electrician or engineer for final design decisions.
You own your data. All calculation history is stored locally on your device. We do not have access to your data. If you delete the app, your data is permanently gone — we cannot recover it.
Some modes (Solar DC, Marine, Industrial) require a one-time Pro purchase through the Apple App Store. All purchases are processed by Apple and subject to Apple's terms. Refund requests must go through Apple.
Use the App for its intended purpose. Don't attempt to reverse engineer, modify, or redistribute the App.
The App is provided "as is" without warranties of any kind. We do not guarantee that the App will be error-free or uninterrupted. Wire sizing results are estimates — the user is responsible for verifying all calculations against applicable codes and standards.
To the maximum extent permitted by law, Digital Copilot shall not be liable for any indirect, incidental, or consequential damages arising from your use of the App, including but not limited to damages arising from reliance on wire sizing results. Our total liability shall not exceed the amount you paid for the App.
We may update these terms as needed. Continued use after changes constitutes acceptance.
