VoltWirer - Five essential calculators built for licensed electricians

Hey Product Hunt 👋 I'm Jonathan, and I built VoltWirer after getting tired of bouncing between five different clunky calculator sites every time I needed to check a wire size or voltage drop on a job. VoltWirer puts the five calculators electricians actually use every day in one clean, fast tool: Voltage drop Wire ampacity Conduit fill Box fill Conduit bending Everything's built on NEC 2026 standards, so the numbers you get are code-compliant, not just "close enough." No sign-up walls, no clutter, no ads slowing you down on a job site with spotty signal — just punch in your numbers and get your answer in seconds. I built this as a solo project because I wanted something I'd actually want to use myself — and if you're in the trade, I think you will too. Would love to hear what you think, and if there's a sixth calculator you wish existed, tell me — I'm actively building this out based on what electricians actually need.
