WireStix: Wire Size Calculator

WireStix Wire Size Calculator makes electrical sizing in panels fast, simple, and consistent. Whether you are in front of a live panel, reviewing photos back at the office, or teaching new techs how to think about wire size, WireStix helps you get to a reasonable answer quickly so you can move on with the job.

Built as a companion to the WireStix physical gauge set, this app focuses on one thing: helping you size and verify conductors in real-world electrical work. Instead of flipping through tables or scrolling through PDFs, you get a focused tool that keeps your attention on the panel, not the paperwork.

Use WireStix Wire Size Calculator to:
• Work through electrical sizing in a structured, repeatable way
• Quickly sanity-check conductor sizes when you are looking at existing work
• Organize how you think about wire size when teaching apprentices and new technicians
• Reference documentation and learn more about the WireStix physical gauge set

The app is designed for:
• Electricians and apprentices
• Home and building inspectors
• Maintenance and facilities techs
• HVAC, solar, and low-voltage installers who regularly deal with conductors and panels

WireStix Wire Size Calculator is also the software side of the WireStix ecosystem. Inside the app, you can learn more about the WireStix physical gauge set and how it is used to identify wire sizes directly in electrical panels. The app and the tool are designed to work together: the gauge gives you a fast physical check, and the calculator helps you think through and document your sizing decisions.

Key goals:
• Keep size selection decisions quick and focused on the field task
• Provide a clean, straightforward workflow for electrical sizing
• Support training by making the sizing logic more visible and repeatable
