CircuitSense is the field calculator built for electricians who'd rather pull wire than dig through code books. Enter your circuits once and it sizes conduit, conductors, and grounds to the 2026 NEC — handling voltage drop, derating, and box fill automatically, with the math shown so you can trust every number. PLAN YOUR CONDUIT Build a complete run from a single input. CircuitSense balances circuits across conduits, picks the optimal raceway size, applies ambient and conductor-count derating, upsizes for voltage drop, and segments the run at every J-box / pull point. You get a full pull schedule with per-conduit fill percentages — before and after each box. EVERY NUMBER, EXPLAINED No black boxes. Each result shows the calculation steps, the NEC section behind it, and an upsize history so you can see exactly why a conductor went from #12 to #8. Perfect for inspections, plan review, or just double-checking your gut. A FULL NEC TOOLKIT Conductor sizing & voltage drop — ampacity, derating, and VD in one flow Conduit fill — by conductor count and type Box fill — NEC 314.16 volume by AWG and device Pull box sizing — 314.28 straight, angle/U, and splice Load calculations — dwellings, multi-family, and offices Fault current — available fault-current estimates Transformer sizing — kVA, amps, and OCPD suggestions Conduit bending — stub-90, offset, 3- and 4-point saddle Panel phasing — see circuit phases by slot (12/24/42) Construction calculator — feet/inches and tape-measure fractions Concrete & trench — slab, footing, trench/backfill, and duct bank ORGANIZED BY PROJECT Group runs under jobs, track which are complete, and reopen any run to tweak and recalculate. Your work is saved on-device and ready when you're back on site. SHARE PROFESSIONAL OUTPUT Export any run as a clean, detailed PDF — conduit schedule, fill, derating, and EGC sizing all included. Hand it to an inspector, a GC, or your own crew. BUILT FOR THE FIELD 2026 NEC referenced throughout Works offline — no signal required in the basement or the bucket Fast, single-input workflow designed for gloves and daylight Copper or aluminum, EMT and more Whether you're roughing in a panel, planning a duct bank, or checking voltage drop on a long run, CircuitSense does the code math so you can keep moving.
