Match the evidence to the claim

Product specifications should identify the exact model, generation, fuel and source. A current manufacturer page or matching manual is the starting point for equipment facts. Safety guidance should link to the relevant official authority or equipment instructions. Local requirements should identify their jurisdiction.

Independent tests can support performance conclusions only within their tested conditions. Owner reports and installer experiences may identify questions worth investigating, but they do not establish a population-wide failure rate. We do not describe document research as hands-on testing.

Compare equivalent systems

A comparison should explain whether the candidates include the same scope: fuel-specific output, transfer equipment, installation assumptions and service arrangements. Equipment MSRP is not an installed quote. A warranty summary should point to the terms for the actual model rather than imply that one headline duration describes every product.

Our evaluation framework sets out the questions behind these comparisons.

Updates and corrections

Reasons to revisit a page include a manufacturer revision, replaced model, changed price reference, new safety guidance or a substantiated reader correction. Source-check dates identify the information checked; they should not imply that every sentence was newly researched on that date.

To request a correction, use Contact and provide the page URL, disputed statement and relevant documentation. A correction should be made where the claim appears so readers do not have to find a separate notice to understand it.

Authorship and commercial independence

The publisher is Backup Generator Guide.com. We do not claim a named expert reviewer unless that person’s participation and relevant role are established. Our current commercial relationships are described in Disclosures.

Limits of planning content

Calculators and checklists organize assumptions; they do not approve an installation or substitute for equipment instructions. Readers should take the resulting load and scope documents to qualified professionals who can assess the actual home and applicable requirements.

What makes a correction request actionable?

An actionable correction identifies the page URL, disputed statement and evidence for the change. For model specifications, include the model number and document revision. For a price, include the date and package scope. Submit that information through the contact page so the specific claim can be reviewed.
