- The electrical worksheet compares 2017 NEC Table 8 resistance at 167°F and flags reactance, ampacity, and installation conditions as separate checks.
Field notes
The page describes searching supplied PDFs and fixed external snapshots, with results tied to a source and locator. Its battery worksheet is explicitly synthetic: it uses 24 hours of standby, five minutes of alarm, and a 20% margin, while warning that other system types may differ. The electrical worksheet uses a historical 2017 NEC resistance table and calls out several factors it does not cover.
