Continuous vs. Startup Power
During a power outage, appliances draw different amounts of power depending on whether they are in steady operation or starting up, making it critical to distinguish between continuous and startup power requirements. Continuous power, or running wattage, is the steady-state energy needed to operate an appliance. Startup power, or surge wattage, is considerably higher and occurs momentarily when the appliance begins operation, such as compressor start-up in refrigerators or freezers. Essential appliances often have a startup power requirement 2-3 times their continuous power. Accurately evaluating both values ensures the generator can handle initial surges without overload. Misjudging startup power risks equipment shutdowns or generator overloads. Consequently, understanding these differences allows for selecting a generator that reliably meets both steady and transient power demands during outages.
