FieldVolt Electrical vs TrueOhm

Built by a licensed electrician for work in the field. PIPE BENDING Offsets, 3-bend saddles, 4-bend saddles, rolled offsets, back-to-back 90s, and parallel offsets. Mark placement calculated from the working end. Shrink, gain, spacing — all of it. CONDUIT FILL NEC Table 1 calculations for mixed wire fills. Add conductors, get fill percentage. AMPACITY Wire sizing and derating for ambient temperature, number of current-carrying conductors, and conduit type. VOLTAGE DROP Feeder and branch circuit voltage drop for single-phase and three-phase systems. BOX FILL NEC 314.16 calculations for device, conductor, clamp, and support fitting fill. FIELDVOLT PRO Ask electrical questions, get straight answers. Code interpretation, troubleshooting, load calc logic — the kind of thinking you'd get from someone who's been in the trade for 30 years. 5 free sessions included. Pro subscription available at $4.99/month or $50/year. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

TrueOhm is a fast, free electrical calculator built for electricians, apprentices, and engineers. Five powerful calculators in one app: • Ohm's Law Wheel — Enter any two of voltage, current, resistance, or power and instantly solve the other two. • AC Power — Calculate real power, apparent power, current, and voltage for single-phase and three-phase systems. • Power Triangle — Solve the relationship between kW, kVAR, kVA, power factor, and phase angle. • Energy Cost — Estimate energy consumption and cost for any load over any run time. • Efficiency — Calculate motor or system efficiency from input and output power. Every calculation shows its work — tap "How this was calculated" to see the exact formulas and substitutions used. Built-in sanity checks warn you about impossible values without blocking your workflow. Designed for the field. No ads. No subscriptions. Just fast, accurate calculations from 509 Electric.
