About Electrical Calc Elite Nec Code

Electrical Calc Elite™ is the electrician's code calculator that follows the NEC® edition your inspector enforces — one purchase, no subscription. Size wire, check voltage drop, fill conduit and size motor circuits — offline, in seconds. Answers that come from a code table print which one. Ten editions of the National Electrical Code® are built in — NEC® 2026*, 2023, 2020, 2017, 2014, 2011, 2008, 2005, 2002 and 1999 — and every table, correction factor and code reference follows the one you select. BUILT FOR Electricians, contractors, estimators, engineers, maintenance techs, inspectors, apprentices studying for the exam, and homeowners checking their work. WIRE SIZE AND AMPACITY • Required wire size in AWG or kcmil from amps: copper or aluminum, single-phase or three-phase, 60/75/90°C insulation, at 100% or 125% • Ampacity in raceway or free air, from the NEC® ampacity tables (310.16 and 310.17, or the earlier equivalents) • Ambient temperature correction above or below 30°C, in °C or °F • Adjustment for more than three current-carrying conductors in a raceway • Parallel and derated conductor sizing • Circular mils and kcmil for any wire size VOLTAGE DROP • Volts and percent dropped from one-way length, amps, phase and wire size, with Chapter 9 Table 8 resistance corrected to 60, 75 or 90°C • Wire size for a long run, flagged VD WIRE SIZE when the drop, not the ampacity table, set it • Longest one-way run a wire size will carry inside your limit: 3% by default, or any limit you set • 1- or 3-phase, copper or aluminum, feet or meters; wire resistance per 1000 ft on its own key CONDUIT SIZING AND FILL • 12 conduit types: EMT, ENT, FMC, IMC, LFNA, LFNB, LFMC, RMC, PVC schedule 40 and 80, Type A and Type EB • Trade size for a mix of THW/THHW, XHH/XHHW or THHN/THWN conductors • Fill percentage, cross-sectional area and area remaining, from the Chapter 9 tables, with the correct 1-, 2- and over-2-wire fill limits • Maximum conductors of a given size a conduit will take MOTORS • Full-load current for 1-phase, 3-phase, synchronous and DC motors, from NEC® Tables 430.247, 430.248 and 430.250 • Horsepower from amps, and full-load amps from horsepower • Maximum fuse and breaker size from Table 430.52 (430.52(C)(1) in 2023 and 2026): single- or dual-element fuse, inverse-time or instantaneous-trip breaker • Motor overload protection sized from nameplate amps, per 430.32(A)(1) • NEMA starter size, per NEMA ICS 2 GROUNDING • Equipment grounding conductor size, per 250.122 • Grounding electrode conductor size, per 250.66 POWER, MATH AND CONVERSIONS • Convert between amps, watts, volts, VA, kVA, kW, power factor %, efficiency % and DC resistance • Ohm's Law: enter any two of ohms, volts or amps to get the third • Kirchhoff's Law • Parallel resistance • BTU ↔ kilowatt-hours • Doubles as a standard calculator, with Store and Recall memory keys CODE REFERENCES YOU CAN CHECK Wire size, fuse, breaker, overload and grounding answers print the table or section they came from, numbered as your selected edition numbers it. Fuse and breaker cards show the percentage of full-load current used and the current it was applied to. HELP ON EVERY KEY Press and hold any key for a help page on that function. A Getting Started guide, worked examples and the full manual are included. WORKS OFFLINE Every calculation runs on the device. No account, no sign-in, no ads, and no signal needed in a basement or a mechanical room.
