About & how this site is built

Who

Built and owned by Jeremy Panasuk, New Auburn, Wisconsin. Contact: [email protected]. Jeremy is a data/software person, not a licensed professional engineer (PE) or electrician. He is not a licensed professional engineer and this site is not a PE stamp. These are planning tools, not professional advice.

How

The calculators use published rules of thumb from the sources listed on each page. Page text is drafted with AI agents (Cursor and local models) from those sources. Formulas are checked against the cited sources. If you spot an error, email [email protected] and it gets fixed.

The lab-tool method is written out on Methodology.

Why

The site earns money from Amazon affiliate links. That doesn't change the math.
