That means an appliance that normally draws 200 watts can have a power spike of around 600 watts when first started. Two devices in particular create massive spikes: a 200-watt refrigerator will need 1,600 watts to start, while a 1/4 HP furnace fan will need 1,600 watts to start and 600 to run.įor other electric motors, you should assume they need three times as much wattage available as it takes to run one of these devices. If a device has an electric motor, it needs more watts to start than it does to run. If you know the appliance’s power in amps, multiply that number by the voltage it uses, either 120 or 240. Keep in mind that quoted wattage is generally for output: a 1,000-watt microwave produces 1,000 watts of heat, but needs more power than that due to inefficiencies and non-heat loads like the turntable and display. To get the best estimate of the power required, use a load tester to get accurate measurements. Which end of that range your home falls in depends primarily on the type of heating systems and water source it uses. How Much Power Do I Need for My Home?įor the majority of homes, 3,000-6,500 watts is enough to power most household appliances. All Honda generators are single phase, so they can’t power devices that require multiphase power like welders. Home appliances typically run on 120-volt power, but some items like well pumps, require 240-volt power. Without this switch in place, the changes in power could cause generator fires and electrocute anyone working on the system. This isolates your home’s electrical system to prevent “backflow,” which is the flow of current back into the grid or the generator. If you’re looking into using the generator as a backup for grid power, it will need to be wired into a transfer switch. For example, if your area has noise ordinances, you may need a quieter EU series instead of an EM or EG Series. EB Series industrial generators have GFCI outlets for ground fault protection.ĭespite these classifications, your needs may fit a different application.EM and EG Series home generators are built to run several hours on each tank of fuel.EU Series RV generators are designed to be quiet.EU-i Series recreational generators are designed to be portable.These are the main differences between the models: Honda divides their generator lines into industrial, recreational and home use. That depends on how and where you’ll use it. Which Honda generator should you buy, though? Need a generator? Honda’s reliable engines, automatic power control and high-quality components make their generators a great choice.
