What Gauge Extension Cord For Table Saw? | Complete Guide

Want to find out what gauge extension cord for the table saw is just right for your work? In this article, we’ll explore the different gauges and discuss how they affect your cord, and how to choose the right one for your workshop. We’ll give you the information you need to make the right choice.

If you are in the market for a new table saw then you need to take a look at the gauge extension cord for the table saw. The blades of table saws can get very hot, depending on the type of wood you are cutting. The last thing you want is the extension cord to melt and cause you to get hurt.

What Gauge Extension Cord For Table Saw

Choosing the right extension cord for your table saw can make a big difference in your ability to do woodworking projects. A quality extension cord is essential for anyone who uses the table saw. Extension cords come in different gauges, and each one has its pros and limitations.

Here’s what you need to know about different gauge extension cords:

12-Gauge extension cord

These are most commonly used for general household purposes. They’re usually rated for up to 120 volts. 

14-Gauge extension cord

It is typically used for commercial applications where higher amperage is needed. These cords are usually rated for up to 240 volts.

These are ideal for use with small appliances such as hairdryers, curling irons, and electric shavers. They are also useful for powering smaller household items such as lamps, fans, and air conditioners. 

16-Gauge extension cable

It is designed for industrial use and is usually rated for up to 480 volts. This type of extension cord is ideal for professional woodworkers.

Things To Consider For Extension Cord For Table Saw

When choosing an extension cord for your table, there are two things to consider:

  • Voltage rating
  • Amperage rating
  • How much power do I need
  • Keep the length of the electrical cord to a minimum

Voltage Rating

Most extension cords are rated for either 120 volts or 240 volts. The voltage rating refers to the maximum amount of current that can flow through the cord. A 240-volt cord can provide up to 1 amp of current, while a 120-volt cord can only provide 0.5 amps.

Amperage Rating

The amperage rating tells you how much current is flowing through the cord. An extension cord with a higher amperage rating means that it can handle more current than a cord with a lower amperage rating.

For example, a 10-amp extension cord can supply up to 10 amps of current, while a 5-amp extension cord can only supply 5 amps.

How Much Power Do I Need?

Before buying an extension cord, you also need to decide how much power you need. This depends on the size of your table saw. If you have a smaller table saw, you may not need a very powerful extension cord.

Keep the length of the electrical cord to a minimum

While the table saw starts it draws many times the rated amps. A 12-gauge extension cord is okay for the running load, but it limits the amperes on start-up. Every extra foot of cord chokes the current flow during start-up. So you have to keep the length of the electrical cord as short as possible.

How Do You Pick The Right Extension Cord For Your Table Saw?

To choose the right extension cord for the table saw, you first need to determine whether you’ll be using it for home or business. If you plan to use the extension cord for home, then you don’t need to pay too much attention to the amperage rating.

You’ll probably only be using it for occasional tasks like powering a small drill or circular saw.

However, if you plan to use the cord for commercial purposes, such as powering a larger drill or circular saw, then you should look into the amperage rating of the extension cord.

In this case, you want to find an extension cord with a higher rating so that you can run heavier equipment without overheating the cord.

There are many different types of extension cords available, each designed for specific uses. Here are the three main categories of extension cords:

  • Power cords
  • Grounded power cords
  • Safety ground cords

Power cords: A power cord is used to connect a power tool to a wall outlet. A power cord usually consists of two parts: a plug and a cable.

Grounded power cords: A grounded power cord is used to provide a path for electricity to flow safely through a circuit.

Safety ground cords: A safety ground cord is used to protect people who come in contact with live electrical wires. A safety ground cord provides a safe path for electricity to travel through a circuit.

How To Choose The Correct Extension Cord Sizes Table Saw

Choosing the correct extension cord size table saw is essential to ensure safety and efficiency. There are two types of extension cords: straight and round. Straight extension cords are usually longer than round ones.

They are made up of three parts: plug, cord, and receptacle. A table saw requires a minimum of 15 amps of current. If you use a standard extension cord, it won’t provide enough amperage to run your table saw. Therefore, you must purchase a larger one.


Length is measured from the center of the plug to the tip of the cord. The length of the cord depends on the type of tool you’re using. When selecting an extension cord, measure the length of the cord. Make sure it’s long enough to reach where you plan to place the cord.


Amperage refers to the amount of electricity flowing through the cord. This number indicates the maximum amount of current that the cord can deliver safely. The higher the amperage rating, the greater the capacity of the cord.

However, there is no guarantee that a higher amperage cord will be able to handle the current required by your tool. Always buy a cord with the highest amperage possible.

Plug Size

Plug size refers to the diameter of the plug. The smaller the diameter, the thinner the wire. Choose a plug with a large diameter.

Receptacle Size

Receptacle size refers to the width of the socket. The wider the socket, the easier it is to connect the cord to the outlet.

Why Understanding Wire Gauge And Amps Matters

Understanding wire gauges and amps matters because understanding these two things will make life easier for you.

Let’s talk about wire gauge first. Wire gauge refers to the thickness of the wire. There are different types of wires used in electrical circuits.

For example, there are thin wires, medium wires, thick wires, etc. Thick wires are usually used for power lines. Medium wires are usually used for low voltage wiring. And so the thin wires are usually used for small appliances.

So what does this mean for you?

If you’re using a thicker wire, you’ll require more amps to run it Amps refer to how much electricity flows through a circuit. If you use too much amperage, your appliance won’t work properly.

Here’s another example. A 100 amp fuse is needed to protect against short circuits. But a 200 amp fuse is needed to prevent overloads. This means that if a 100 amp fuse is used, you’ll need to increase the circuit’s current capacity by 50 amps to prevent damage.

Now let’s talk about amps. Amps measure the flow of current. The higher the number, the greater the current.

For example, a 20 amp fuse protects against a 20 amp current. A 40 amp fuse protects against a 40 amp current. 60 amp fuse, 80 amp fuse, and so on are used for protection against the 60 amp current, 80 amp current respectively, and so on.


Q: What Is Considered A Heavy-Duty Extension Cord?

The heavy-duty extension cord is one that is designed to withstand higher voltages and currents than regular cords. They are usually rated 10 amps or higher and are made of thicker wires. They are typically used for power tools, appliances, and lighting.

Q: How Many Amps Can A 12 Gauge Extension Cord Handle?

12 gauge extension cord can handle up to 16 amps.

Q: How Many Amps Can A 14 Gauge Extension Cord Handle?

A 14 gauge extension cord can handle up to 12 amps.

Q: How Many Amps Can A 16 Gauge Extension Cord Handle?

16 gauge extension cord can handle up to 7 amps.

Q: How Many Amps Can A 18 Gauge Extension Cord Handle?

16 gauge extension cord can handle up to 5 amps.
