Surge protectors should have a joule rating of 1080 if I want to keep my sewing machine safe. We’ll go into more detail about surge protectors and whether or not you need one to protect your sewing machine in the following section.

For those familiar with the terminology, we’ll explain the need of surge protection and how to identify the Joule Rating you require. However, do you know how many watts the sewing machine uses??

Sewing machines are not designed to draw a lot of power There are machines, however, that require a greater amount of power.

What Are Joules?

When measuring the amount of energy that has been released over time, the joule is used. One billion joules of energy are released in a fraction of a second during an average lightning strike.

Joule ratings indicate how much energy can be absorbed before a surge protector breaks. Surge protection is enhanced by a higher joule rating. Type and value of protected equipment are important factors to consider when determining the appropriate level of security.

Valuable Equipment Needs a Higher Joule Rating

Inquiring minds may be asking, “How much surge protection do I need?” Whether you’re safeguarding a $500 PC or a $5,000 home theater depends on the response. A surge protector with a greater joule rating is necessary if you have valuable equipment. Surge protection can benefit any device plugged into an AC outlet, although low-cost items like lamps, digital clocks, and blenders don’t require a high level of protection.

These little devices can safely be protected by a surge protector rated at up to 1000 joules. Protective circuitry is needed for some components that contain sensitive electronics, but do not retain a lot of data. Power tools and office equipment like printers, copiers, and routers can be adequately protected with surge protectors rated at 1000 to 2000 joules.. Consumer electronics like home theater systems and gaming consoles with joule ratings above 2000, as well as computers that store sensitive data like customer lists or bank records or irreplaceable photographs and other records, should all be given the utmost priority.

Location is also a Factor

A higher level of protection is needed in places where lightning storms occur on a regular basis. When it comes to electrical surges, Mother Nature isn’t responsible for all of them. Power surges can also be caused by problems with the utility provider. The usage of power tools and heavy machinery in industrial settings can result in surges and line interference that can be destructive.

Most surges start within the home or business, even in the quietest residential neighborhood. Small surges, which you may not notice when power tools, air conditioners, or even refrigerators and ovens start up and shut down, might damage your electrical devices. This type of voltage surge can’t be prevented by a whole-house surge protection system.

How a Surge Protector Works

Surge protectors suppress excessive voltage when it increases above a permissible level, protecting the system from damage. An internal component known as a metal oxide varistor (MOV) is responsible for absorbing any excess voltage and securely sending it to the ground line.

Is Your Surge Protector Still Working?

However, most kinds of surge protectors have an LED that indicates the presence of protection even if the protector itself does not show how many joules it can provide. However, if the surge protector is tucked away beneath a desk or behind a piece of furniture, these lights may go unnoticed. Surge protectors aren’t built to last a lifetime. It’s a wonderful opportunity to invest in new surge protectors if you’ve had a big electrical event, such as lightning, that resulted in a power outage or if your units have been in operation for some time.

How Many Joules Of Surge Protector To Protect My Sewing Machine?

Your machine requires a surge protector with 1080 joules of protection. For added peace of mind, a security system with an alarm or light is highly suggested.

High-end and computerized electric sewing machines must be protected from electrical surges for household or electric use. To be safe, it’s best to consult with an electrician about how many joules your sewing machine needs in terms of surge protection.

Can I Plug My Sewing Machine Into A Surge Protector?

If you don’t use surge protectors, your sewing machine is more prone to catch fire than other electronic and digital gadgets. In some areas, a surge protector for your home may be required by the local construction inspectors.

High-end sewing computers, in particular, should be protected from power surges and blackouts at all times. Your machine’s expected lifespan in the event of power outages, such as those caused by lightning or a breakdown in the power grid.

If you use a surge protector, you’ll have more peace of mind knowing the equipment won’t be damaged. A modern machine’s delicate parts could be more sensitive to variations in the current.

It’s possible you’ll read in the manual that the machine needs a constant current running at the correct voltage in order to work properly. What’s most important to remember is that your sewing machine is just as vulnerable to damage from a power surge as a high-end computer.

Do surge protectors actually do any good?

Depending on the model, surge protectors can protect sewing machines as well as laptops and electronic gadgets. If, for example, you fail to unplug your sewing machine during an unexpected storm, you could run into trouble.

There could be a slew of devices in your house that are power hogs. This could increase the load on the grid and lead to spikes.

An overvoltage protector will divert it to a grounded wire when it is detected. Consequently, they protect the electrical components of your devices from high voltages.

Is it too tough for you to operate an electronic machine? To find out which one is better for you, compare a mechanical and an electronic sewing machine.

How Do I Choose A Joule For My Surge Protector?

Depending on how you view your equipment, several people recommend a surge protector with a higher joule rating. Because of this, low-end electronics like lamps and blenders don’t need the same joule ratings as, say, an entertainment device surge protector.

In general, a surge protector with an energy rating of 1000 joules is enough to protect most devices from power surges. More than 2000 is excellent for devices with sensitive electronics and substantial data storage capacity in the event of an electrical surge.

What Does Joules Mean On Surge Protector?

The amount of energy dispersed by a surge protector is measured in joules. More power it can absorb before needing to be replaced means a higher joule rating.

As a result, it’s easy to see why a high-quality surge protector is a superior investment. For the sake of argument, let’s assume that the 1,000 joules is more effective at keeping your gadget safe.

During times of high power, surge protectors protect electronic appliances and gadgets such as sewing machines. As a result, household appliances will last longer if there are no problems with its electronic components.

How do you choose the right surge protector to meet your requirements

  • Inquire about whether or not it has been certified by Underwriter’s Laboratories (UL).
  • Use the joule rating that corresponds to your appliance.
  • Check to see that the surge protector has enough ports to accommodate your needs.
  • Clamping voltage is the amount of voltage that a surge protector can protect against
  • Indicators of the surge protector’s security must be clearly displayed.
  • Pick an acceptable warranty for your surge protector.

What Are Surge Protector Joules and What Joule Rating Do You Need?

What Is a Power Surge?

As the name suggests, a power surge occurs when the electrical current in your home surges. A thousandth of a second is all it takes for the spike to cause catastrophic harm to your electronics and home appliances if you don’t have the proper protection.

What Causes a Power Surge?

Lightning and high-power electrical devices are the primary causes of power surges.

Appliances might be damaged even if lightning strikes far away from your home. If it hits a power line in any way, it can generate an electrical current surge. This can spread to your home and cause your computer or television to malfunction.

Lightning can’t be protected by any surge protector on the market. Your home should be fully protected in the event of lightning strikes. Lightning arrestors can be used to deflect the bolts to the earth. Most major US cities have high crime rates, making extra security for your property a must. Roofing businesses like Castle Roofing and Chad Dodson Roofing are also recommended by many electricians. Get a good roofer and an electrician in your region before you need them.

Power surges can also be caused by high-power electrical devices.

Refrigerators and air conditioners are examples of high-power gadgets that are already in your home. When these appliances are turned on, a surge of electricity is released that can damage nearby electronics.

Inadequate electrical wiring (such as outdated or damaged wiring) exacerbates the issue.

Understanding Surge Protectors

Why would a surge protector be useful then?

When there is a spike in power, your surge protectors can handle it. If your surge protector doesn’t have a high enough clamping voltage or joule rating, it won’t be any use to you.

As a result, understanding how surge protectors function is critical. In the end, you’re just squandering your money if you buy the wrong one

Clamping Voltage

Clamping voltage is the amount of voltage it takes for the surge protection to activate. The better the protection, the lower the voltage should be set.

How many joules your surge protector can handle doesn’t make a difference. Even a minor power surge can destroy your equipment if the clamping voltage is high enough.

Clamping voltages in the range of 330 volts are common in most standard surge protectors. Anything having a voltage greater than this should be avoided at all costs.


How much energy is dissipated by your surge protector depends on its joule rating.

But what does this really mean?

A surge protector’s joule rating indicates how much power it can withstand. The greater the rating, the better the protection.

When comparing the lifespan of two surge protectors, a 1,000-joule protector is going to last longer than a 500-joule protector will.

How Many Surge Protector Joules Do I Need?

Depending on the type of equipment you’re trying to protect, the amount of surge protector joules you require will vary. If you just purchased a $1,500 laptop, you’ll need more joules of protection.

To help you choose what kind of protection you need, below is a joule rating guide.

500 to 1,000 Joules

Avoid joule rates below 1,000 unless you are protecting small devices that do not hold vital data. However, if you’re protecting stuff like blenders or table lamps, a lesser rating suffices.

Because of their compact size, you may easily tuck these surge protectors beneath furniture or other items. They may be used in a variety of settings, from a home office to a kitchen counter, thanks to their compact size.

A surge protector with a low joule rating is also the cheapest solution. You may want to consider this surge protector if you’re on a tight budget and only have a few small devices.

1,000 to 2,000 Joules

Surge protectors with this wattage level are suitable for office equipment such as printers and copiers.

Surge protectors with a joule rating of 1,000 to 2,000 joules are recommended for devices such as cell phones, laptops, printers, routers, and copiers.

Your power tools and other construction appliances will work OK with this rating as well.

2,000 to 3,000 Joules

Get a surge protector with more than 2,000 joules to protect expensive or delicate equipment.

Computers, game consoles, and home entertainment equipment are all included in this category. These surge protectors are essential for businesses that store sensitive data such as client information or financial papers on their computers.

When to Buy a New Surge Protector

Surge protectors aren’t built to last a lifetime.

Cheap surge protectors may fail after a single power surge if they have low joule ratings. Higher joule rated surge protectors may last longer, but they will degrade over time.

This means that purchasing one surge protector will not suffice.

There are LED lights on most surge protectors to indicate the protection is still active. While it won’t tell you how many joules are left, if the surge protector stops operating, it will turn itself off.

Keep an eye on your surge protectors if you store them out of the way or behind furniture. After a spike in your home’s electrical current, it’s a good idea to check or replace your surge protectors.

Buying the Right Surge Protectors

Consider purchasing a surge protector with a high grade of surge protector joules for those who own expensive equipment or need to safeguard vital data. For enterprises, this is even more critical.

Losing important data can have a negative impact on your company’s performance and lead to additional expenses.
