Why does the horse power of the motor matter? I want to use this with a 15 amp miter saw, but the manufacturer doesn't give a horse power rating.

Horse power shouldn't matter, I just mentioned it in my comment because they stated it should work for routers up to 2 1/4 HP.

there is 746 watts per horsepower if the voltage is 110 and the current is 15 amps the wattage is 110*15 = 1650 watts which is 2.21 hp. 20 amps at 110 volts is 2.94 hp

On 110v motor the larger the horse power, The higher the amp draw. If you are running a large 110v motor and under load and it is drawing over 20 amps. It will keep blowing the fuse or burn this unit up.

Yes, I would say horsepower matters, but this is related to the amperage. I use this speed control on a router that is also 15 amps and it works great. I'm not sure why you would want to change the speed of a power miter saw, but this unit should work fine.

Not sure. Mine is on a 15 amp circuit and has never kicked the breaker. Almost all of the draw is at startup and that is handled by capacitors, once the blade is in motion there is enough inertia that I've never noticed it slowing down (and thus requiring additional current draw) for anything I've ever cut with it, which is most generally oak or dimensional softwoods. I'm not outside at the moment (recovering from eye surgery yesterday), so I can't check the motor for its specs. Try the Makita web site for detailed electrical specs.

Says 1.7 amps on the sander data plate. Seems like the motor has a lot of power for that low of an amperage rating.

The ohms law answer is incorrect. Manufacturers always use a current rating in their UL safety application which is much higher than the devices actual usage. A better way to calculate the wattage is to work backwards from the horsepower. There are 746W to 1HP, so a 1/2 HP motor will use 372W.

I run my ten inch hitachi miter saw on it. Had to mount it to a piece of 3/4 plywood then mounted stand feet to the plywood!! Works great!

As long as the motor is wired for 120 volt, it will work just fine. There are jumpers that need to be set in the Motor for 120 or 220 volt operation.Make sure to ask somebody who knows how to do it. My saw was already wired for 120 volt.

The key is your extension cord. Be sure you use one that's rated for 15 amps or you are risking burning out the motor.

It's 2 hp and let me tell you how good it is. I found out about this saw from a older friend who is an electrician. He said it worked very good especially lighter weight and not having to deal with mix fuels/oils and such. So I bought one. I have been cutting huge 18-20" timber and it just keeps up as well as my Poulan or my Sthil. Just make sure your chain is tight and you keep the chain oiler filled.

I also looked in my book and couldn't find the info either. I didn't see the information on the saw either. This is a light weight saw. I have used mine quite a bit over the years I've had it. I works great. I did find a phone number you might want to try. 1-877-bosch99. Maybe they have the info you want.

A 2 hp motor @120v draws 20 amps. The rating on relay contacts is only 15amps. So no.

It will draw 15 amps at start. It does not have a soft start. That being said this is a great quality saw. Very light weight but very versatile and quality tool. I would buy this tool over and over again.

The answer to the horse power of the Grizzly model G0715P Polar Bear series is 2 HP. It is a 10 inch saw with all the power you need. The saw is well built and very accurate and to say the least I really like this saw a lot. Great buy.

Ohms law says amps X Volts = Watts, So with the information provided the compressor runs on 120 volts at 15 amps will be 1800 watts. However when this compressor motor starts under a load I'll bet it spikes upwards of 20 amps probably around 30 amps so if your going to use a power inverter to run this compressor better be a good one ! At least 3600 watts at the minimum

It will run it, I used it to run a dewalt circular saw. Its a modified sine wave instead of pure sine wave, its not the best for electric motors. Long term tool use i dont recommend.

Depends on the starting current draw of the saw's motor, but I suspect the motor might blow the fuse on the controller which is 15 amps. The startup current of the saw may be more than that.

Bit works fine for me....I would suspect too deep a cut rather than the motor. Try several shallow cuts if you haven't tried this already. Note that I used a Porter Cable model 6912, which is 1 3/4 hp, same as the router power you used. Of course if the router vibrated before it touched wood then you have a balance problem. Unlikely.

Assuming they haven't made any improvement in the blades, just added more power to the motor, the 1.5 amps in extra current is worth about one-fifth of an extra horsepower over the 13.5 amp model. Seems like a bit much when the price is 40% more for just a 10% increase in power. For what its worth, I own an SJ620 from 4 years back, and love it. Not sure if I would have gone for a more powerful model if it had been available at that time.
