TrueMotor is a focused NEC Article 430 motor-calculation app for working US electricians — the clean, correct tool for the branch-circuit math people get wrong by hand. Pick the motor, get the answer in seconds, and see exactly how it was calculated. THE SINGLE-MOTOR BRANCH CIRCUIT — FREE • Full-load current from NEC Table 430.250 (three-phase) and 430.248 (single-phase), by horsepower and voltage — the table value, used per 430.6(A), not the nameplate. • Branch conductor sized to 125% of FLC (430.22) against NEC 310.16 ampacity, copper or aluminum, 60/75/90 °C termination column. • Branch overcurrent device — the 430.52(C)(1) maximum by device type (non-time-delay fuse, dual-element fuse, inverse-time breaker, instantaneous-trip breaker), rounded to the next standard 240.6 size. • Overload from the nameplate FLA (430.32) — 125% or 115% by service factor and temperature rise. MULTI-MOTOR FEEDER — TRUEMOTOR PRO • Feeder conductor — 125% of the largest motor's FLC plus the sum of the rest (430.24). • Feeder OCPD — the largest branch device plus the other motors' FLCs (430.62). • An editable motor group — add and remove motors, each with its own branch result feeding the feeder. SHOW YOUR WORK — every result expands to reveal the NEC table row, the multiplier or factor, the formula, and the exact code section. Nothing is hidden. NEVER RECOMMENDS AN ILLEGAL PAIRING — TrueMotor cross-checks conductor ampacity (310.16) and standard device sizes (240.6) and warns, in plain language, if something doesn't line up. BUILT FOR THE FIELD — light and dark themes, Universal iPhone and iPad layout, and calculations saved locally on your device. TrueMotor is a calculation aid for qualified professionals. It does not replace code review, engineering judgment, the equipment listing, or the authority having jurisdiction. From 509 Electric — the same team behind TrueBend, TruePhase, TrueFault, TrueRate, and TrueDrop.
