Decisions. Decisions.

I thought I was ready to get in the Grizzly G1023RLX line. Then I saw the G1023RLX5. The fundamental differences are 3HP vs 5HP, 240V 20A (6-15P) vs 240V 30A (L6-30P), and $100 more for the 5HP unit.

I suspect that the 3HP version will meet or exceed my needs. Clearly, the 5HP will easily exceed them.

So, is the extra 2HP worth $100?

I would say yes, only a $100 extra. Sort of why not. But at the same time I would buy the 3hp version. I simply do not need that much saw. And I have used both 3 and 5 hp saws. I really did not notice a difference. I did very much notice the difference between my 1.75 and 3hp.
I am a hobby woodworker and do not do much in the way of production work. I get by fine with my 1.75. So for me 3hp would be a dream in its self.

I suspect this is correct.

However at 100 bux it could be a deal maker on resale, and the old point of have you ever heard someone complaining they had too much power?

IMHO – Decision is little more complicated than cost for different motor?

The power specs given by Grizzly do not met NEC section 430 building code for motor driven appliances.
They only specify absolute minimum plug required to use with the tool. Suggest you research the difference between NEC code table FLC and name plate FLA as part of your purchase?

In another thread discussing new shop power requirements, I cover the topic in this post.
Short version: 3HP requires 30A breaker protected circuit, and 5HP requires a 40A breaker protected circuit.

Some folks might think my mention of code requirements is overboard BS.

Be first to admit that I have run several 5HP motor on 30A circuits, and they work most of time. But when you load up big heavy 7/8” wide dado on 5HP TS, about 1 in ~25 starts it will ‘nuisance’ trip the 30A breaker, due normal surge of extra blade load. No big deal?
Household breakers are not designed to be used like switch, and have finite trip cycle count. After ~100 cycles the trip earlier with lower current. Eventually the nuisance tripping wears out the breaker, it trips more frequently, and it has to be changed.
With proper sized 40A circuit for 5HP, have can not remember my last nuisance breaker trip? YMMV

PS – Start up surge on loaded motor is ~3X FLC/FLA. That is why circuit needs to be oversize compared to slower acting thermal over load protection in motor starter.

Can only believe half of everything you see in forums? Please do not believe this random engineer, spewing code requirements in forum. Ask your local licensed electrician; how to met code for both 3HP and 5HP motor in your shop.

Best luck on decision.

I would get the 5. You can’t have too much power.

Honestly I was disappointed the first time I used a 3hp cabinet saw in comparison to contractors. Was hoping for more.

5 HP needs to be direct wired by most codes. Check yours. My only 5 HP is my ClearView, and it has never tripped on a 30A, (recommended by ClearView) With that massive steel blower, I bet the startup is higher than a saw. More mass, but the saw will have more friction from the belts. There are also differences in motors.

There is nothing wrong with a circuit having a bit of overhead, so if pulling wire for a 5 HP saw, I would pull 8 gauge. I think you move to stranded at that size. Like for a dryer.

On the resale, most people do not have 40 A branches. So it may be harder to sell a 5 HP than a 3.

I an not sure what a 3 HP won’t do on a 10 inch saw. 12 inch sure. Heck, my contractor saw did everything IF I used thin kerf blades. My 3HP ( Harvey) has not slowed down on anything yet, though I have not tried to cut a 2 inch x 3/4 inch dado in purpleheart in one pass. If I was looking at a 5 HP, I might be looking at 12 inchers.

Klutz, could your breaker be fatigued? Enough trips and they do trip at a little lower threshold.

I owned the 5HP Grizzly 12” G0696X BEAST and never tripped the 30amp breaker. Whether the motor was actually producing 5HP or just generously rated at 5HP peak during a full moon when aligned with the earths poles who knows.

Having never used a 5hp saw, all I can offer is that I’ve never even slowed my 3hp Shop Fox W1677. The extra power for $100 seems reasonable in theory, but your needs will determine whether or not it’ll ever get utilized. On the other hand, that $100 will buy a really good saw blade.
