No. The code does not require a neutral on 240 circuits. What was changes was electric ranges and cook tops and ovens. In the past, these items bonded the neutral to ground at the device and combined neut and gnd. That is what changed to require a neutral with a 240 v circuit. The saw only requires 240 and a ground, but no neutral. And if powered by 120 v, the saw is required to be GFCI protected, as are all other 120 v circuits in a garage or shop. So bottom line is, change to 240 operation.

I was being facetious. Luckily, the OP hasn't been back since the second post.

@Rick Christopherson : That is my understanding. I don't know when it came into being, but it only seems to apply up to the receptacle. I have not read it in the code. Plenty of tools (e.g Harvey) don't have a neutral wire and it is certainly not necessary for safety. OTH, i have run into appliances that require neutral for the reason stated above. There are lots of things in the code that never made sense to me; this is one that kinda-sorta makes sense, but the thinking part of me says, "If you don't need it, why pull it?"

It's not code. Care should be taken when writing with authority (as an authority) when the information is only speculative.

The original poster has not returned since the beginning of this thread, but as I stated a couple days ago, he needs to first find out why an unloaded 2hp motor is tripping a newly installed 20-amp breaker. That should not be happening; so something else is wrong. Throwing a larger breaker at it, or rewiring for 240-volts is not the automatic solution until the original issue is determined.

You are absolutely right and I stand corrected. It is not code, and I erred in that statement.

I know I am late commenting on this thread. I think that the motor is a cap start and you tried to start it on an undersized circuit and that burned out the capacitor. Is that is why you had a new circuit installed?

This thread has slightly worried as I'm getting my new Harvey ( same model) delivered tomorrow. I have plenty of power in my shop. But only have one 240v outlet on opposite side of the shop where my welder stays, ugg

 

[Hunter734]

Fwiw the chart I see on Harvey's website only shows 16A draw with no recommended breaker size

Is there space in your electric box for another 240v breaker? It wouldn't be that difficult to run a line for the saw.

The 16 amps is for 115v. A 20 amp breaker with 12 gauge wire would supply enough power. Generally it's a good idea to size the breaker where the draw is 80% of the breakers limit which would be 16 amps.

There is spare space. But the whole reason I went with a 2 hp saw was for the mobility of being able to move it around as needed. I should have went with a 3 HP as it stands now.
I do appreciate all the advice. When I get it sorted out I'll be sure to post the results

If your house is new chances are the circuits are 15 amp which would be too small for that saw. An older house will generally have 20 amp circuits for the outlets which would work for you. If you went with 3 hp you wouldn't have a choice but to supply 220v to it.

I have a newer garage with a 100A service. I'm fortunate in that aspect. Was just hoping 20A would be good as I have those outlets on all walls. It's always something lol

Like I said a 110v 20amp circuit would work for that saw.

Hey Steve I appreciate your advice and you were correct. I just fired up my new 2hp saw on the 110v 20A circuit with no issues.
I'm not a really experienced woodworker, but wow this saw is half as loud and twice as powerful as my 25 year old craftsman was. For anyone looking for a new table saw sign up for Harvey's email flyers. They have great flash sales. I got this one for 1775$ plus shipping and tax.
It came with compass miter that I haven't opened up yet. A regular insert, a dado insert, 2 thriving knifes, overhead dust collection. I really like it so far

If you are in a position where you are ripping hardwood for hours at a time you might consider re-wiring it to 220v. The motor won't heat up as fast on 220v.

Don't make me...

The motor doesn't know the difference. It won't run cooler. It won't have more power.

I've done it both ways and it helps.

 

[Hunter734]

I'll borrow a amp draw meter from my electrician coworkers just to see what the actual draw is. I'm a skilled trades guy at a large auto plant.
I'm sure it would be more balanced on 220 if I remember correctly from what I've learned over the years from the electricians I've worked with.

My guess is the OP figured it out…
