How Many Amps Does a Table Saw Use?

Table saw is a basic tool for woodwork projects at home or professionally. Before you begin using the table saw or any other tool, you must know what kind of work can be done on this device, and how many amps does a table saw use. This information will not only help you setup the device well, but will also give you an idea about the kind of work you can do with it. 

How Many Amps Does a Table Saw Use

Machinery that requires high input is usually heavy-duty work and will not be suitable for small projects, and vice versa. A table saw is a basic cutting device but it can prove useful for various home and professional works. The electric fundamentals are essential knowledge for all woodwork enthusiasts because it helps understand the maximum output of your tools.

Watts, Amps and Volts for table saw

The watt is the measure of power and it is the rate of work done when one ampere current flows through it. Similarly, voltage is the potential of electricity flow between two points, Amperes are the measure of electricity. The current is the number of electrons that flow through a body, and amperes measures this quantity in a circuit. All these definitions do not mean anything when your focus is to work with wood. However, it is good knowledge to understand how much energy your table saw will be needing. 

Watts, Amps and Volts for table saw

The horsepower or the energy required by the table saw can also be explained as hunger. The more electricity your saw needs, the more power it will have to work on the wood you feed it! 

How Many Amps for a Table Saw?

Table saw and most of the rotary motor tools need more power to start than they need to run. If you have a mediocre-sized table saw, which means that it can cut up to 3-inch thick wood panels, the power input required will not be too large.

The bigger table saws that are used to cut thick logs, and saw the tree trunks in halves and quarters will require more power to run, and will also require a greater wattage to start. When you use a table saw for home projects, the maximum amount of power it uses will be no more than a vacuum cleaner. 

While the startup power is much higher, users will also have to consider the power needed to run the tool consistently. If your table saw uses 1,800 watts for running, it will require almost three times the wattage to start.

The most common sizes for table saws used in workshops and home workstations is around 1800 watt. This table saw can cut up to 2.5 inches thick wood pieces, and can run for long period of time. The amps consumed by this size of table saw is up to 12 amps, which can be easily catered by a 15-amp electricity supply.

The electric panel in workshops and at workstations for a medium-sized table saw will have to be in accordance with this consumption so that your work is not interrupted while the machine works consistently. 

There are a few tips that can help ensure that the power output is not disturbed. 

Tips to Ensure Smooth Running of the Table Saw

If you have an electric panel that gives you up to 15 amps of electric current, some tips will help ensure that the power and voltage remain constant and you can cut wood properly.

Tips to Ensure Smooth Running of the Table Saw

Use only one machine at a time

If you use more than one machines of a 15-amp current supply, the voltage on each of them will drip and the machine may fluctuate in power. The best way to ensure smooth working, and consistent work flow will be to use only one motor or machine at a time. This will mean that each machine gets its required wattage and amperes and will not drop in efficiency. 

Update the wiring

Updating the wiring to reduce wastage and consume electricity more efficiently. Old wires often have resistance and this can mean a drop in current flow. The newer wires will have no resistance and electrons will be able to move freely along the conductor. Too much physics? We ensure you that this simple explanation will help you understand how to use your table saw more effectively without wasting electrical energy. 

Circuit beakers

A circuit breaker is a safety shield to prevent your machine from burning out in case there is not sufficient current flow. The more secure the circuit is, the safer your table saw will remain. Many work stations suffer losses due to lack of circuit breakers. 

By following these small steps, you can ensure an efficient and well-working machine that will not use too much electricity and the output will remain good. 

Some Related Questions

Can I use a table saw with a 5KVA generator?

The medium-sized table saw that consumes around 12 amperes of electric current can be used with a generator. However, it is recommended that you use it on the main grid, or a bigger generator. This is because if the wires are old or if there is a project that requires the generator to run for a long time, the table saw may burn out. 

Will a medium-sized table saw require a circuit breaker?

We always want every user to apply things that will improve the life of their machinery. Table saw is a simple cutter and if it is being used for a long time, a fluctuation in voltage can destroy the motor. To ensure smooth and consistent flow of electricity, use a circuit breaker for the safety of the saw. 


Table saws are available in various sizes and the medium-sized one is most common. The ampere consumption of this table saw is up to 12 amperes. You can try a few ways to ensure that the machinery works well and does not consume a lot of electricity due to resistance in the wires.
