110 vs. 220 Table Saws - Which is Better for You?
If you have the budget for a 220V table saw, get the 220V table saw. For anyone that is an aspiring woodworker or simply looking to upgrade their current table saw, one that is wired for 220V is almost always the best bet. The only exception to this is if you are limited by your budget and are an infrequent user.
Otherwise, looking at table saws that run on 220V offer many more features than their 110V powered counterparts. Saws powered on 220V (same as 210, 230, 240V) offer stronger motors, greater power efficiency, and a host of other features that only offered on higher grade table saws.
4 Benefits of a 220V Table Saw
220V table saws offer two primary benefits that lead to several other benefits. For one, most better, higher-end table saws run on 220V and two, 220V table saws offer significantly more power.
Better Table Saws Run on 220V
Higher end table saws run on 220V power due to the size of their motor needing more power at a given instance. Purely from a marketing standpoint, those who need more power will be the heavier users of the product, and thus there’s a greater availability of features on table saws that run on 220V power.
For example, the SawStop Professional Cabinet Saw (PCS) 5HP has many features beyond the standard jobsite saw, including:
- Cast iron top
- Premium fence system, option for T-Glide style fence
- More precise angle adjustment
- Model-specific accessories made by the OEM and third parties
Access to More Power
With a 110V table saw you’re typically limited to the available power on a 15A circuit. This can be an issue when ripping through a dense hardwood like maple. Your standard jobsite saw may not have a motor that can handle making a deep cut through dense wood. Other times, the circuit your saw is connected to may not have enough available power to feed the motor.
Having more power behind each of your cuts increases the efficiency of the cut and results in a smoother and better cut. The motor can draw the necessary power to drive the saw blade through thick and dense material. When the blade can move through the material quicker and smoother there’s a lesser likelihood of burn marks or binding of the blade.
Less Likelihood of Power Interruption
For a 220V table saw, you’ll likely have a separate outlet that runs on a dedicated breaker. Assuming you install the correct size breaker, the saw can draw all the power it needs to make cutting through thick material faster.
A 110V saw connected to your standard 15A outlet may be sharing the capacity of the breaker it’s connected to. For example, your entire garage may be on a single 15A circuit. Your lights, garage door, and other tools all run on the power connected to this circuit.
If using shop vac and job site table saw at the same time it’s very likely you’ll run into a scenario where you trip the breaker and the whole garage will go dark. Shop Vacs use around 8 to 12 amps and when the table saw is trying to draw up to 15 amps from the circuit to power the motor, you may trip the breaker.
Longer Lasting Tool
In the long run, a 220V saw with a 3HP will likely outlast and outperform a 110V saw with a 1.75HP motor when cutting the same amount of wood the same way. The 220V saw is built to withstand more abuse and 3HP is often more than enough for even some professional woodworkers, let alone hobbyists.
You’ll rarely ever be pushing a 3HP saw’s motor to its capacity and thus there is less wear and tear on its inner components.
3 Factors to Consider for a 110V vs. 220V Table Saw
Added One-time Electrical Costs
A 110V table saw does not require any additional costs to install. Simply plug it into any wall outlet.
A 220V table saw will likely require a separate outlet to be installed on its own breaker. In theory, you could potentially use the outlet that your dryer is plugged into, but constantly unplugging and then plugging in the dryer isn’t practical.
The cost to install a 220V outlet shouldn’t be more than a few hundred dollars for parts and labor from an electrician. If you’re feeling confident in your DIY work, this is something you can do yourself and there’s plenty of video tutorials online for how to do it. Before starting that, I recommend you read the upgrade information section towards the end of this article.
Your Home’s Max Amp Service
For most newer homes, built around 2010 or later, you probably have 200A service going into your home. Meaning, your whole house has the ability to use up to 200 amps before tripping the master breaker. For older homes, some may have 200A service, but most will have 100A or 150A.
The main concern is for homes that have 100A service, as a 3HP 220V table saw will need around a 25A to 30A dedicated breaker to run. This could be an issue in that your home may not have enough available capacity for that size of a breaker.
That’s not to say you can’t run the saw. You can run the saw even if your home has 100A service, but you’ll want to be conscious of any other electrical devices or appliances that have a high amp draw. Things like the dryer, your oven, vacuum cleaners, or any other item that has a heating element or motor attached to it.
You don’t want these running while you’re running the table saw, else you may end up tripping the master breaker.
Frequency of Use
If you frequently use a table saw, then this doesn’t take much thought. It’s a bit of waste to buy more power than you need and if you aren’t planning to work your home shop regularly, then a 220V table saw simply doesn’t make sense. If you are somewhat infrequent in your projects, but still want a high quality saw, a contractor’s saw is a great option.
SawStop’s Contractor Saw provides many of the same benefits as its professional cabinet models, but with a smaller motor and lower price point. There’s no need to do any electrical work as this saw can plug directly into the wall.
110V vs. 220V Table Saw Upgrade Recommendation
Run a sub-panel
If you’re going to run a 220V outlet, I highly recommend running a subpanel from your main breaker box. The amount of work is only a little bit more than running a single 220V/240V outlet, but provides you with a ton of flexibility later on down the road.
The reason for this is you can then run other outlets, lights, and other items directly from the subpanel box and in the end, it only takes up a single breaker in your main panel.
This is something I had done in my home that had a 200A breaker box. I ran a 60A sub-panel from the main breaker. From the sub-panel I ran several more 15A outlets, a 220V/240V outlet, and an electric vehicle charger. Additionally, the area is set up to run additional lighting in the garage and replace the two measly bulbs that there.
Work with solid wire
If you’re wiring this up yourself, solid wire is typically easier to work with than stranded THHN wire. Buy about 20% more than you think you’ll need and be consistent in your color coding. The standard wiring color codes are as follows:
- Green = Ground
- White = Neutral
- Black = Hot
- Red = Hot
These wire colors may differ depending on when and where your home was built. It’s always best to remain consistent with what is already in your home and keep adequate documentation easily accessible.
