I recently moved into a rental house while I’m stationed in Virginia and the garage at the house only has 15 amp circuits. I have a Grizzly G0715P hybrid table saw that I have a NEMA 5-20 plug on as Grizzly recommends.

Question is, being that I do not have 20 amp circuits in the garage and would like to avoid any modifications to the house, can I install a 15 amp plug on the saw and use it? Grizzly claims the motor draws 16 amps at 110v however the wiring is 14 awg and I know 12 awg is required for 20 amp circuits while 14 is for 15.

Would this work or will I just be tripping breakers? Has anyone successfully done this? Thanks as always for any advice and enjoy the weekend!

Honestly, I’d be very surprised if that would work w/o tripping the breaker. Someone correct me if I’m wrong, but I believe that normally breakers will trip around 80% of the rated amperage, so on a 15A circuit, you’re really only looking at about 13A of usable.

I had a G0715P briefly and I had quite a few problems with it tripping my 20A 110v circuits. Remember that whatever you do, don’t simply swap out that breaker for a 20A breaker.

Unfortunately, I think your only recourse here is to install an actual 20A circuit with 12ga wire. Hopefully the owner lets you do that.

+1 on buzz’s comments, with the following info.

depending on what is also on the circuit with the TS and operating while the TS starts up, a 15A breaker will probably trip. the motor ratings are usually full load amps, i.e., the amperage the motor would draw at full load, or when it is doing the most work spinning the blade. at start up, there’s a chance the saw would start without incident, even given the start up surge, provided there’s nothing else operating on that circuit. however, apply a load to the saw, like ripping a thick piece of hardwood with a 40 tooth blade, and the odds are very good that the breaker will trip.

-- there's a solution to every problem.......you just have to be willing to find it.

Thanks for the replies!

I ended up giving it a try with a NEMA 5-15 plug and so far, so good. Saw starts right up and I’ve ripped 8/4 alder with it and havent tripped a break so far, even with me attempting some pretty forceful ripping speeds to see if it would.

Have your say...
