No collection or tracking
The checker performs its calculations in your browser. It does not send your entries to a server, use cookies, use localStorage or other browser storage, run analytics, show advertising, or load remote scripts.
Links and hosting
The page includes links to independent reference sources. Those sites have their own privacy practices. The static site may be delivered by Cloudflare Pages; this tool does not add tracking code or accounts.
Not professional advice
The output is an estimate and planning comparison, not a safety clearance, electrical design, inspection, code-compliance decision, or installation approval. Follow product labels and consult a qualified electrician when conditions are damaged, hot, wet, repeatedly tripping, unknown, fixed, or unusually complex.
