About ElectricalSuite

ElectricalSuite was founded with a straightforward goal: to build clean, fast, and accessible calculators for electrical trade professionals, engineers, and students. Electrical layouts require extreme precision, and we believe that the tools used to check code compliance should be simple to use, transparent, and completely free.

Our Mission

We aim to simplify calculations based on the National Electrical Code (NEC). Rather than hiding the math behind black boxes, our calculators show the direct formulas, constants, and references from the NEC tables. This transparency helps users understand the mechanics behind their calculations, making the tools useful both for verifying field layouts and for preparing for licensing exams.

Core Principles

• No Tracking or Collection: We respect your privacy. All calculations are performed directly on your local device via client-side JavaScript. Your input data is never sent to our servers.
• NEC Compliance: We build our logical formulas around standard NEC tables, such as Table 310.16 for conductor ampacities, Chapter 9 for conduit dimensions and fill limits, and Articles 240, 430, and 440 for breaker sizing.
• Speed and Accessibility: No registrations, no subscriptions, and no paywalls. Open the tool you need and calculate instantly from any browser or device.

Disclaimer: While we verify our formulas for accuracy against code specifications, ElectricalSuite is designed solely as an educational and cross-checking reference tool. Always consult a licensed electrician or electrical engineer before executing physical electrical work.
