Store description excerpt
Five NEC calculators for electricians in one offline app — voltage drop, conduit fill, conduit bending, box fill, and wire size / ampacity. Free to use. No signal in the mechanical room, the basement, or a rural panel? Fieldwatt runs 100% offline. Once it's loaded, every calculation works with zero bars — no login, no waiting, no paywall on the math. ═══════════════════════ FIVE CALCULATORS, ONE APP ═══════════════════════ ⚡ VOLTAGE DROP Size a run and check % drop in seconds. Copper or aluminum, single- or three-phase. Based on NEC Chapter 9, Table 8. ⚡ CONDUIT FILL Drop in your conductors and get fill % instantly. All common conduit types and wire sizes, per NEC Chapter 9, Tables 1, 4 & 5. ⚡ CONDUIT BENDING Offsets, saddles, and 90° stubs without the head-math. Get your marks fast and bend it right the first time. ⚡ BOX FILL Count conductors, devices, clamps, and grounds and stay legal under NEC 314.16. ⚡ WIRE SIZE & AMPACITY Look up conductor ampacity and size by insulation temperature rating and conditions, straight from NEC Table 310.16. ═══════════════════════ BUILT FOR THE TRADE ═══════════════════════ • Dark "field-instrument" UI — amber on charcoal, easy to read in a dim panel room or bright sun • Big tap targets that work with gloves on • Live results that recompute as you type • Every answer cites the NEC table or section behind it • NEC 2023 reference values Whether you're pulling wire, bending pipe, filling boxes, or studying for your journeyman or master exam — the numbers you reach for most, in one fast app. ═══════════════════════ FREE TO START ═══════════════════════ All five calculators are free.
