About the service

Backup Generator Guide is an independent research publication. It provides general information to help readers compare backup-power options and prepare questions for qualified professionals. It does not manufacture or sell generators, install equipment, arrange financing or provide emergency services.

Use of the site does not create a contractor, engineering, advisory or other professional-client relationship. Contacting us does not engage a professional to assess your property or equipment.

Research and professional decisions

Articles describe general scenarios and published equipment information. They are not a site-specific electrical design, installation approval, code interpretation or instruction to perform hazardous work.

Have qualified professionals assess electrical loads, transfer equipment, fuel supply, placement, permits and service requirements. Follow the exact equipment manufacturer’s instructions and applicable local requirements. In an emergency, contact the appropriate emergency service or utility.

Specifications, prices, warranties, product availability and local requirements can change. Check the exact model, fuel, configuration and current source before relying on a statement. Document research is distinct from independent hands-on testing. Our evaluation approach and editorial policy explain the evidence framework and correction process.

Calculators and downloads

Calculators and worksheets provide estimates based on your inputs and the assumptions shown with each tool. They do not verify the accuracy of your inputs, recommend a particular model or establish that equipment will safely power your home.

Sizing results do not certify startup performance, fuel-specific capacity or installation suitability. Runtime results estimate fuel duration; they do not establish safe uninterrupted operating time, maintenance intervals or fuel-delivery capacity. Preserve the tool’s assumptions and limitations when sharing a result, and have the proposed system checked independently.

Permitted use and intellectual property

You may read the site, link to its public pages, and save or print reasonable copies for personal research or internal planning. You may use the provided worksheets to discuss your own project with a contractor. Keep relevant source attribution and limitations with copied materials.

Original text, graphics, design and software are protected by applicable intellectual-property rights. Except as allowed by law or an express permission, do not republish substantial portions, sell copies or present our content as your own. This provision does not restrict fair use or other rights granted by law.

Manufacturer names, trademarks, photographs and source materials belong to their respective owners. Their appearance does not establish sponsorship, endorsement or a commercial partnership.

Responsible access

Do not use the site to submit spam, malicious code or another person’s confidential information, interfere with its operation, bypass access controls or conduct unlawful activity. Automated access must not overload the service or bypass technical restrictions. Ordinary linking and lawful citation are welcome.

We may restrict access that threatens site security or availability. Content and tools may be revised, moved or withdrawn, and uninterrupted access is not guaranteed.

Messages and corrections

Submit only material you have the right to share. Sending a question or correction allows us to review it and use the relevant factual information to investigate or improve the publication. It does not transfer ownership of your original material or authorize publication of your private contact details.

We cannot guarantee a response or adoption of every suggestion. Our Privacy Policy explains how contact messages and other information are handled.

External websites and commercial relationships

Third-party links are provided as research references. We do not control those websites, their accuracy, availability, products or services. Any purchase or service arrangement you make with a third party is between you and that provider.

Our disclosures describe the publication’s current commercial relationships. No listing or mention guarantees a contractor’s qualifications, availability or suitability for your project.

Disclaimers and limitations

To the extent permitted by applicable law, the site and its tools are provided “as is” and “as available,” without warranties of accuracy, completeness, fitness for a particular purpose or uninterrupted operation. Research and estimates cannot eliminate the need for professional assessment.

To the extent permitted by applicable law, the publisher is not liable for indirect or consequential losses arising from use of or inability to use the site, including decisions based on incomplete, outdated or incorrectly entered information.

Nothing in these terms excludes responsibility that cannot lawfully be excluded or limits mandatory consumer rights. These terms do not require arbitration or waive a right that applicable law protects.

Updates and questions

Revisions will appear on this page with an updated date. Changes apply prospectively and do not remove rights that already apply under law. If any provision is unenforceable, the remaining provisions continue to apply to the extent permitted by law.

For a question about these terms or permission to reuse material, use the contact page and identify the page or material involved.
