What size breaker do I need for a 5500 watt generator?

So, 5500 watts / 220 volts X 0.80 = 20 amps. If you have a 30-amp breaker, you should have plenty of amps to handle the element, associated electronics (which typically only draw a few hundred milliamps), and probably a couple March or Chugger pumps, too.Click to see full answer. Regarding this, what size breaker do I need for a 8000 watt generator?It’s typical to use a 30-amp breaker for generators up to 8,000 watts and a 50-amp breaker with 8,500- to 15,000-watt generators.Subsequently, question is, what size breaker do I need for a 5500 watt water heater? The math shows that 5500 watt water heater is well within the safe maximum for a 30 amp breaker and 10 gauge wire. When heat exceeds circuit breaker rating, then the breaker trips. A 30 amp breaker with 10 gauge wire has 80% safe maximum = 24 amps. 24 amps x 240 volt = safe maximum 5760 watts. Herein, what can you run on a 5500 watt generator? In layman’s terms, a 5500 watt generator can run almost any essential household appliance, including: Small window AC unit. Fridge with a freezer. Microwave oven. TV. Sump pump. Small heating system. Computer. VCR / DVD Player. Will a 7000 watt generator run central air?Although a 7,000 watt generator might not be able to run a large central air conditioning system, you should know that it can easily run a sump pump, a ½ horsepower furnace and other appliances or equipment that run on an electric motor.
