A tool designed to estimate the power requirements of electrical devices, enabling appropriate generator selection. For example, a household preparing for a power outage might use such a tool to determine the generator size needed to run essential appliances like refrigerators, sump pumps, and lighting. Inputting the wattage of each appliance allows the tool to calculate the total power demand, guiding the user toward a generator with sufficient capacity.
Accurately assessing power needs prevents generator overload, which can damage both the generator and connected appliances. It also helps avoid purchasing an undersized generator, ensuring critical systems remain operational during outages. Historically, generator sizing involved manual calculations and often resulted in inefficient or inadequate power supply. Modern tools streamline this process, providing precise estimates that promote safety and optimize resource utilization.
