Question 1

Is this electrical load calculator app really free?

Accepted Answer

Yes, it’s completely free with no in-app purchases, ads, or data collection. You can create unlimited projects and export PDFs without paying a cent.

Question 2

Does the app work offline on iPad and iPhone?

Accepted Answer

Absolutely. All calculations are performed locally on your device. iCloud sync requires internet, but you can use the app fully offline and sync later.

Question 3

What NEC code version does the app use?

Accepted Answer

The app is built on NEC 2023 standards, including demand factors for lighting, receptacles, motors, and HVAC. We update the code base annually to match the latest edition.

Question 4

Can I use this app for commercial and industrial load calculations?

Accepted Answer

Yes. The app supports single-phase and three-phase systems up to 600V, with demand factors for commercial kitchens, laundries, and industrial machinery per NEC Articles 220 and 430.

Question 5

How does the app save my work? Does it crash like other apps?

Accepted Answer

Your work is saved automatically to local storage and iCloud (if enabled) every 5 seconds. In beta testing with 50,000+ calculations, we had zero crash-related data loss.

Question 6

Can I export my load calculations to share with inspectors or clients?

Accepted Answer

Yes. You can export any project as a clean PDF with your loads, demand factors, total VA, and recommended panel size. No watermarks or branding.

Question 7

Does the app handle voltage drop calculations?

Accepted Answer

Yes. Enter conductor size, material, and distance (up to 500 feet). The app calculates voltage drop percentage and suggests a larger conductor if needed, per NEC recommendations.

Question 8

What if I need to calculate motor loads with starting current?

Accepted Answer

The app includes a motor load calculator that applies NEC Table 430.248 for full-load current and recommends a breaker size based on 250% of FLA for the largest motor.
