Will a 2.8 generator run a 15 amp electrical motor?

[rocktot]

This generator Im looking at would be nice, but its only 2800 watts. With the startup surge, will it power something at 15 -16 amps? Im thinking electric log splitter.

I'm a bit rusty but 110 volt times 15 is 1650 watts. Treat this like internet reloading data.
OHMS law is what your looking for.

The formula for finding wattage is: Volts x Amps = Watts

Motors present a totally different issue:

Electric motors present a special problem. They require up to three times their rated wattage to start.
Example: an electric motor name plate states 5 amps at 120 volts, 5 amps x 120 volts = 600 watts.
Multiply this by 3. This will show the starting watts needed. 600 watts x 3 = 1800 watts to start.

Power(watts)/voltage=current

2800w/110v=25.45amps or maybe I really have no clue.

According to sellersm post you can handle 8.5 amp motor start.

Ok, thanks

Rate your generator as you would a circuit breaker if using it for electric motors. 125% of motor rating or you could have problems tripping the generator's over current protection when the motor starts.

I have a 1850 surge generator, it loads down pretty good when the furnace motor starts up. FYI. Log splitter, will do the same I'm sure.

I think I will wait around for a larger one. Thanks

yeah you will want something at least 4500 watts if you are going to run something like that. check out costco, you can pick up 6000+ watt generators for a good price and they typically have a good warranty.
I bought my 2000W inverter generator there for my camper and love it.

What is rated hp of motor? Is the motor single phase or three phase? The generator will need to be able to handle the in rush current which is 7x FLA

[sniper7]

costco had 2 really nice ones last night. 1 was honda engine powered, I think 7000 watts, $1000. the other was I believe champion model 8000 or 8500 watts, $700 i think

lots of generators on craigslist, decent stuff, decent prices.

Just some examples, coleman brand, couple honda's out there @ decent $. Yamaha, if you're not needing portability, a couple of Onan gensets from motorhomes out there.

just like mine: $275, another listed there for 250.

Another solution to motor start load currents is to build soft start modules for them. It is not to hard to build them yourself if you have some electro-mechanical abilities. This also extends the life of the equipment both on the generator and load system side.
