I have a Briggs & Stratton Storm Responder generator that is rated at 5500 watts with a 8250 startup watts capacity. The user manual is a little confusing: it seems to state that I have to take the starting wattage of each appliance into account when I compute the wattage load so I don't exceed the maximum running capacity (5500 watts, in my case). So what do I do with the "8250"? How does that factor into the equation?
motors have a surge load upon starting which is higher than running load requirements. Use the rated amps of desired appliances or tools,that will be fine when matched with running wattage of the generator. remember Watts = Amps x Volts 5500/110 = 50 amps A couple of caveats though: older motors may not be as efficient as factory specs. Longer wire runs reduce amp rating as does undersized wire. Also, hot wires have reduced carrying capacity Cold motors have higher surge than warmed up motors. Example: A 15 amp old air compressor may trip a 20 amp breaker. hopes this helps
