- The homepage lists 21 appliances and 49 cited primary sources, and says test conditions are shown for figures such as pump flow at a 10-foot lift.
Field notes
The generator example distinguishes steady demand from startup demand: its listed appliances total 2,450 W running and 4,650 W at the starting peak. The sump-pump material compares Liberty, Zoeller, Wayne, and Basement Watchdog, and reports flow at a stated 10-foot lift. The site says its calculators expose their formulas and its figures link to numbered sources; it recommends checking results with a licensed electrician.
