Terms of use
Last updated: June 2026
By using wiregaugechart.com you agree to these terms. If you don't agree with them, please don't use the site. They're written to be readable rather than intimidating, but they do matter — especially the safety section.
Safety disclaimer
This site is an educational reference about wire gauges and is not professional electrical advice. Sizing conductors and protecting circuits is safety-critical work governed by the National Electrical Code and local amendments. The data here — dimensions, resistance, and ampacity — is presented for learning and quick look-up, often as simplified or before-derating values. Real installations depend on insulation type, ambient temperature, conductor bundling, terminal ratings, voltage drop, and code requirements that this site cannot evaluate for you. Always confirm against the current code and have work designed, installed, or inspected by a licensed electrician. You are responsible for how you use the information.
No warranty
We work to keep the figures accurate and well-sourced, but everything here is offered on an "as is" basis and may change or be unavailable at any time. We make no warranty — express or implied — about its accuracy, completeness, fitness for a particular purpose, or continuous availability. Standards and code editions are revised over time; a value that was correct when published may not reflect the edition that applies to your project.
Liability
We accept liability only to the minimum the law allows. Worklifted Technologies and its contributors are not responsible for any loss, damage, injury, or cost that results from using, or relying on, this site or its content. If the site isn't useful to you, the appropriate response is simply to stop visiting it.
Acceptable use and content
You may use the tools and read the reference material freely for personal and professional purposes. Please don't attempt to disrupt the service, scrape it abusively, or republish its content as your own. The site's text, design, and original data compilations remain the property of their owner; external standards referenced here belong to their respective organisations.
Changes
We may update these terms as the site evolves; the date above shows the most recent revision, and continued use after a change means you accept it.
