Size of the Generator Needed to Run a Circular Saw

Most of the circular saws are portable and can be used in remote areas, which gives it a great superiority over other types of saw, but the portability of circular saw also requires a consistent power supply for the saw to work. Whether you are working in your workshop or remote area, a generator would ensure the required power to run your circular saw consistently.

The Size of the Generator Needed for Running a Circular Saw

There are dozens of portable generators available, each with different power output levels and intended uses. This can make choosing the right model very confusing. To help you pick the right size generator for your circular saw, here’s what you need to know about how they work together and how they impact your productivity and safety while working outside or in the garage. A circular saw runs on a certain volt and watt of electrical power input. If you connect a circular saw with a lower Voltage and lower watt electricity supply, then your saw will either stop working or will work slowly. So choosing the right power generator for your circular saw is important. And choosing the right size of generator depends on the power required to run your circular saw. And you can find it yourself by calculating the electricity input required for your circular saw for optimum performance. Besides, choosing the right generator will save your circular saw from any damage made by a lower or overpowering supply.   

How to Calculate the Electricity Requirement for your Circular Saw?

Calculating the electricity requirement for your circular saw means knowing how many watts of electricity you will be using when the saw is running. And calculation can be done using different input information about your saw. These are how many Amperes your saw uses and how many voltages are required to run your saw. And the formula for calculating the watt required for your circular saw is (Ampere x Voltage = Watt); for example, if your circular saw uses 15 amperes and uses 120 voltages, then your saw will require a power connection of (15*120) = 1800 watt of electricity. You can find the power required for your circular saw on a sticker where the input information is given, or you can look for the user manual of the circular saw. There you might find the electricity input information of the saw. It is possible that the ampere information is not given there only watt required and Voltage required is mentioned. In that case, you can also calculate ampere by simply dividing watt by Voltage.   

What Size of a Generator do you Need?

Factors to consider for choosing the right generator for your circular saw.

There are different circular saws available for cutting different types of materials. The generator size requirement also varies based on the type of circular saw you are using and the watt requirement for your circular saw. And knowing what type of generator is appropriate for your circular saw largely depends on knowing these two facts. first, consider

  1. What is your circular saw type? and,
  2. What is the electricity input requirement for your circular saw?

For example, If you are using a Sidewinder circular saw for woodwork, you will require less power for cutting works of wood, and this machine also uses less electricity as well. For these reasons, the power generator capability requirement for this saw is low. On average, this type of circular saw uses 1400/1500 watts. And you can use any generator that has a power generation capacity of 1800/2000 watts.

And if you are using a heavy-duty circular saw with higher RPM, then the power requirement can be around 2500-4000 watts. Although a general estimation for an average circular saw is that most of the circular saw use around 10-12 ampere and 120 voltage motors and that indicates an average watt requirement for a normal circular saw is around 1200 watt of electricity, but the saw need 2400 watt of electricity to start spinning initially.

Other Factors to Consider

In other factors, we considered the portability, type of material you are cutting, how many tools you are using at a time, size and thickness of a blade.

Some other things to consider when making a choice of buying a generator for your circular saw. These things also affect how your circular saw will work and the overall cutting time required for your saw. Without considering the following factors purchasing a generator may not work best for your saw.

  1. Portability of the Generator.

If you purchase a generator for cutting work with a circular saw, portability should be a big concern for the generator. People who work with a circular saw sometimes require moving from place to place where a stable electricity supply is not certain. For example, if you go to the wood for cutting wood with your saw, then a generator is a must for you, but carrying a heavy generator can be a burden at that time. So it is recommended to consider the portability of the generator too.

  • Type of Material you are Cutting.

The type of material you will cut also affects the power usage, thus the generator. If you cut metal with a circular saw, then the required rpm and electricity supply requirement will be high, but in the case of woodcutting, the electricity requirement will be low; thus, the generator power requirement will be below.

  • How many Tools are in Use?

While using a generator for electricity supply during work, you won’t be using only a single circular saw. Many other electrical devices such as light bulbs and fans of your workshop can be used. Besides, the circular saw’s initial spinning requires a higher electricity supply than the normal requirement. And considering this fact, your generator should have a power capacity of at least 2.5 times your circular saw’s calculated power input requirement.

  • Size of the Blade

The size of the blade also affects how much electricity watt will be required for your circular saw to work. A circular saw with a small diameter will need less power than a circular saw with a big diameter. On average, a circular saw with 7.5 inches of diameter, considered a small saw, will require around 900 watts to work, but in the case of 12 inches diameter, the required power can be 1200-1500 watts.

Bottom Line

When purchasing a generator for your circular saw, you have to know the basic electricity requirement of your circular saw precisely. And the factors that can affect electricity requirement. And using the calculation method and considering these factors mentioned precisely, you can find the appropriate generator for your circular saw. With this guide to make the right choice, you should not face any difficulty next time while making a purchase decision.
