About this app
SPARKIQ puts the NEC 2020 in your pocket.
Designed for licensed electricians and electrical professionals, SPARKIQ delivers fast, accurate code calculations on your Android device — no internet connection required.
WIRE SIZING
Calculate the correct wire gauge for any circuit. Select amperage, wire type (THHN, XHHW, USE, and more), and installation conditions. Results reference NEC 310 tables directly.
BOX FILL
Verify box fill compliance per NEC 314.16. Add conductors, devices, clamps, and fittings — the app tallies required cubic inches and tells you whether you're within code.
CONDUIT FILL
Calculate conduit fill for EMT, RMC, IMC, and flexible conduit. Add multiple wire types and sizes, and instantly see whether you're within the 40% fill limit per NEC Chapter 9.
CONDUIT BENDING
Compute offset bends and saddle bends. Enter the offset height and multiplier — SPARKIQ gives you exact mark locations for clean, code-compliant bends.
NEC NAVIGATOR
Browse common NEC 2020 code references by topic. Keep critical articles, tables, and ampacity values at your fingertips without hunting through the codebook.
WIRE SIZES BY TYPE
Reference conductor ampacity ratings for THHN, THWN, XHHW, USE, RHW, and more. Covers 14 AWG through 1000 kcmil.
BUILT FOR THE FIELD
- Works offline — no internet required for calculations
- Fast interface designed for one-handed use on a job site
- Dark mode for low-light environments
- NEC 2020 / NFPA 70 compliant references
SUBSCRIPTION
SPARKIQ includes a 7-day free trial. After the trial, a subscription is required to continue using all calculators and reference tools.
Perfect for journeyman electricians, master electricians, electrical contractors, apprentices studying for licensure, and inspectors needing quick code lookups.

What’s new
• Fixed: subscribing failed on Android. The app could not reach its server, so checkout showed an error and pricing fell back to placeholder values. Purchases now work and the app shows live pricing.
• Free trial terms are shown in full wherever the trial appears: when it ends, that a payment method is required, the price after, auto-renewal, and how to cancel.
• All prices stated in U.S. dollars.
• New: Fault Current calculator (NEC 110.9).
