What Elecatrix Publishes
Elecatrix publishes U.S. electrical calculators for conduit layout, wire sizing, raceway fill, voltage drop, load calculations, motors, circuits, lighting, PV systems, backup power, and field testing. Each calculator is built around a specific electrical task with defined inputs, units, formulas, and results.
Who the site is for
Elecatrix is written for electricians, contractors, engineers, estimators, instructors, and students checking electrical values before layout, estimating, design review, troubleshooting, or study.
What we publish
Calculators handle focused calculations with defined inputs, units, formulas, and result fields. Guides explain field procedures and concepts. Charts, formulas, and downloads provide supporting reference material as those resources are published.
How pages are maintained
Calculator behavior is maintained in the Elecatrix calculator system so the displayed inputs, result structure, formula basis, warnings, and tests stay connected. Editorial pages are maintained as WordPress content and should be updated when their sources, scope, links, or practical guidance change.
How to use results
Use Elecatrix results as planning and reference aids. Always verify the applicable code edition, authority having jurisdiction, manufacturer instructions, engineered documents, equipment ratings, and actual job conditions before installation, inspection, or sign-off.
Find a tool or report a correction
Start with the calculator library or browse the Guides. If a label, formula, link, or reference looks wrong, send the details to Elecatrix.
