All the foregoing comments are good. Different blade, separate circuit. I’m of the “Tim “The Tool Man” Taylor” school of thought. More horsepower! as the third solution. While the wrong blade will bog down almost any saw under the right (i.e., worst) conditions, having enough power to do the job is another. I’ve literally burned up cheaper table saws, replaced motors, etc, trying to do too much work with them (thick or continuous ripping usually). A good (true) 3hp/240V. Unisaw or Powermatic will make quick work of 8/4 maple (or 12/4 for that matter). I’ve never been able to bog down my Rockwell unisaw and I’ve cut plenty of 8/4, 12/4 and (in two passes) 16/4 stock.

One more idea. When ripping thick stock, I will often resort to the bandsaw—-my Hitachi B600 resaw will rip anything you throw at it—even if it does have that crappy “3hp” universal (screamin’ demon) motor on it. With a much thinner kerf, and a good skip-tooth blade, this is the perfect time to call on the bandsaw for support. You’ll have to joint the faces afterwards, but you’ll do that anyway on most TS cuts.

Ok, one last thought, if you can manage it. Rewire your saw for 240v. That will reduce the current in the motor and it may run cooler. Not sure if your saw supports that or if you can manage that in your shop. Sounds like you may be electrically limited as it is. But if you are going to put in another circuit anyway…just a thought.
