WHAT'S INSIDE - Voltage Drop. Single- or three-phase, copper or aluminum, with drop %, voltage at the load, and the smallest wire that holds your target. - Wire Ampacity. Adjusted for ambient heat and bundled conductors. - Conduit Fill. EMT, rigid, and PVC, with the 53 / 31 / 40% limits applied. - Conduit Bending. Offset, rolling offset, three- and four-bend saddle, 90 degree stub, and back-to-back, with per-size take-up. - Box Fill. Required volume from conductors, devices, clamps, and grounds. - Ohm's Law. Solve any two of V, I, R, and P. - Three-Phase Power and kVA to Amps. - Motor Full-Load Current by horsepower. - Unit Converter. AWG to mm2, kW to HP, F to C, ft to m, and more. THE BEND ANGLE LEVEL Turn your phone into a digital angle finder. Lay it on the conduit and read the bend angle live, hands-free, with a set-zero reference. Most apps charge for this. Codewire includes it free. SHOWS ITS WORK Every result has a tap-to-reveal with the formula and method behind it, so apprentices learn the why, not just the number.
