Frequently Asked Questions
- Which NEC code editions does Conduit Fill support?
- Conduit Fill supports four NEC editions: 2017, 2020, 2023, and 2026. Switch editions in one tap and every calculator recalibrates automatically. Tables follow the National Fire Protection Association (NFPA) published values for each edition.
- What calculators are included?
- Sixteen calculators: pipe fill, conduit sizing, pipe bending, voltage drop, wire size, ampacity derate, box fill, EGC sizing, GEC sizing, motor FLA, transformer sizing, generator sizing, service entrance, load calc, pull tension, and Ohm's Law.
- Does Conduit Fill work offline?
- Yes. Every NEC table is on-device. The app works fully offline - in basements, crawlspaces, or anywhere without signal. No data is sent to external servers.
- Why does the app cite NEC tables in every result?
- Every output references the NEC table or section it came from (e.g. Chapter 9, 310.16, 250.66, 250.122, 220.82, 314.16(B)) so the math is defendable when an inspector asks. Always confirm against the NEC edition adopted by your local Authority Having Jurisdiction (AHJ).
- What is Field Mode?
- Field Mode enlarges tap targets and adds haptic confirmations so the app stays usable with gloves on at the job site.
- How does the license stamp on PDFs work?
- Go to Settings → License Information and enter your name, license number, and state. That information renders into every PDF you export. You are responsible for the accuracy of the credentials you enter. Information stays on your device and is only written into PDFs you export.
- How accurate are the calculations?
- Conduit Fill computes deterministically from published NEC tables. However, calculations may contain bugs or transcription errors and Conduit Fill is NOT a substitute for the National Electrical Code, the AHJ, or a licensed electrician. Always verify every input and every output before relying on a result for any installation.
- How do I report a calculation error?
- Email support@pandataps.com with: (1) the input values you entered, (2) the result Conduit Fill returned, (3) your expected result, (4) the NEC table or section reference, and (5) the NEC year selected. We respond within 24 hours.
- How do I delete my data?
- All data is stored locally on your device. To delete: Settings → Account & Data → Delete All Projects wipes the local database. Uninstalling the app also removes all data.
- How do I cancel my subscription or get a refund?
- Subscriptions are managed by Apple. To cancel: open the iOS Settings app → Apple ID → Subscriptions → Conduit Fill. For refunds, visit reportaproblem.apple.com. Panda Taps LLC has no access to your billing details. The Lifetime purchase has no recurring charges to cancel.
- What does the Lifetime purchase include?
- The Lifetime purchase ($69.99 one-time) unlocks all 16 calculators, every NEC year (2017 / 2020 / 2023 / 2026), unlimited project saves, inspector-ready PDF export with license stamp, and photo attachments on calculations. It grants access for the lifetime of the App's availability on the App Store.
- Does Conduit Fill require iOS 17 or later?
- Conduit Fill is built with modern Swift and SwiftUI for performance, reliability, and accessibility. Check the App Store listing for the current minimum iOS requirement.
- What permissions does Conduit Fill require?
- Camera permission only if you tap the camera icon to capture a photo for a project. Photo library access only if you choose to import an existing image. Conduit Fill never accesses these in the background and never enumerates your photo library.
- Is my data shared with any third party?
- No. Conduit Fill has no third-party analytics SDKs, no advertising SDKs, and no tracking SDKs. Calculations, projects, photos, and license-stamp information all stay on your device. See the Privacy Policy for full details.
