The numbers
Published calculators state the method, assumptions, and sources relevant to their results. Some tools are limited to arithmetic or reference information; they do not select equipment or establish code compliance. A result applies only to the inputs and limits shown on its page.
Your responsibility
A licensed electrician should do the installation. Local rules can be stricter than the tables on this site. Do not copy a result onto a permit without checking the assumptions on the card.
