What Is The Meaning Of An Electrical Power Surge?

In today’s modern world, we depend heavily on electricity to power our homes and devices. However, every now and then, we may encounter an electrical power surge that can cause disruptions and potentially damage our electrical appliances. But what exactly does the term “electrical power surge” mean? In this blog post, we will explore the meaning of an electrical power surge and its potential effects.

Understanding Electrical Power Surges
An electrical power surge refers to a sudden increase in the voltage flowing through an electrical circuit. These surges can last for a very short duration, typically milliseconds, but can have far-reaching consequences. Power surges can occur due to a variety of reasons, such as lightning strikes, faulty wiring, power outages, or even when high-powered electrical devices are turned on or off. Regardless of the cause, power surges have the potential to cause significant damage to our electrical equipment.

Effects of Power Surges
The effects of power surges can vary depending on their intensity and duration. In some cases, a brief power surge may go unnoticed, while in others, it can lead to immediate damage. Here are some common effects that can occur due to power surges:

1. Damage to Electrical Equipment: Power surges can cause severe damage to sensitive electronic devices such as computers, televisions, and home appliances. The sudden increase in voltage can overload the circuits, causing components to short-circuit or burn out. This damage can result in costly repairs or, in some cases, the need for complete replacement.

2. Data Loss: Power surges can also affect electronic devices that store data, such as computers or external hard drives. When a power surge occurs, it can cause data corruption or loss due to the disruption of the device’s internal components. This is especially problematic if you haven’t backed up your important files regularly.

3. Fire Hazards: In extreme cases, power surges can create a significant fire hazard. When the voltage suddenly increases, it can generate excess heat, which can cause electrical wires to overheat and potentially ignite nearby flammable materials. This not only poses a risk to your property but also to the safety of you and your loved ones.

Protection Against Power Surges
Considering the potential risks associated with power surges, it is essential to take measures to protect your electrical equipment and appliances. Here are some steps you can take to safeguard against power surges:

1. Surge Protectors: Installing surge protectors throughout your home can provide a significant level of protection. These devices work by diverting excess voltage from power surges away from your electronic devices. Make sure to choose surge protectors that are specifically designed for the equipment you are using.

2. Unplugging Devices: During a thunderstorm or when you’re away from home for an extended period, it is advisable to unplug sensitive electrical equipment. By doing so, you eliminate the risk of power surges damaging your devices, ensuring their safety.

3. Whole-House Surge Protector: If you live in an area prone to frequent power surges or lightning strikes, you may consider installing a whole-house surge protector. This device is connected directly to your electrical panel and offers comprehensive protection to your entire home’s electrical system.

4. Regular Maintenance: Ensuring your home’s electrical system is in good working condition is crucial in preventing power surges. Regularly inspect your wiring, outlets, and circuit breakers for any signs of damage or wear. If you notice any issues, it is best to contact a professional electrician for repairs.

An electrical power surge refers to a sudden increase in voltage that can cause damage to our electrical equipment and potentially pose risks to our safety. It is imperative to understand the meaning of power surges and be aware of the potential effects they can have. By taking proactive measures, such as installing surge protectors, unplugging devices during storms, and conducting regular maintenance, we can protect our homes and ensure the longevity of our electrical appliances.

Can I Learn To Be An Electrician Online?

Can I Learn To Be An Electrician Online?

Electricity is a very important aspect of our lives. We use it to power our homes, our offices, and everything around us. It is essential to have proper electrical wiring and systems to avoid accidents, injuries, and even fatalities. That is why electricians are in such high demand.

For years, traditional electrical training courses were the only option for those who wanted to become electricians. However, in recent times, people are turning towards online courses to meet their needs. Online education has advanced dramatically over the last few years, but is it possible to learn to be an electrician online? Let’s take a closer look.

Can an online course teach you everything?

Online electrician courses can teach you some of the theoretical aspects of electrical systems. You can gain an understanding of the principles of electricity, electrical safety, electrical systems design, and installation. After completing the theoretical aspects, you can learn and enhance those skills with a practical experience program.

Online courses are designed in such a way that some courses provide constant access to instructors who are always ready to help you answer any questions you may have. The courses can supplement you with a variety of study materials, including video tutorials, reading materials, and quizzes.

However, electrical systems involve practical work, and that’s what makes learning to be an electrician a bit challenging online. It is not possible for an online course to give you hands-on experience with electrical systems. But, with practical training, in-person internships, or on-the-job learning, the skills learnt through online e-courses can be honed and amplified.

An online course can provide you with the foundation of electrical knowledge and help place you in the right direction. However, it is essential to have real-life experience under a knowledgeable practice to ensure that you learn the subtle nuances of being an electrician. In essence, online courses alone are rarely enough.

Are online courses accredited?

Accreditation is an essential characteristic that highlights the credibility of an online course. You need to check if the course you choose is legitimate and accredited by an authoritative body. Check for a course authorized by the National Electrician Association and National Joint Apprenticeship Training Committee. Enrolling in an unaccredited online course is a waste of time and a significant loss of essential skills in your career advancement.

Pros of online training

Online training has many benefits despite not offering hands-on experience. Some of the advantages of learning to be an electrician online are:


Learning online provides a flexible schedule for individuals to accommodate working on their electrical projects. The majority of online courses offer pre-recorded lessons, enabling electricians to progress through the curriculum on their schedules.


Another advantage of online learning is the cost. Online courses are typically less expensive than traditional electrical courses, less room and board needed. Additionally, transport and commuting expenses are not a burden on the electrician. It is a significant consideration for learners who have a limited budget but need to gain knowledge.

Self-Paced Learning

Online courses often enable electricians to work at their most optimal pace and schedule. Whether you want to learn at night or early hours of the day, you can interact with your study material, quizzes and assignments whenever the right time comes.


Online classes offer electricians an opportunity to learn from anywhere, provided there is a reliable internet connection. It means they can learn while travelling, on breaks, or at home. It eliminates commuting time to and from class or laboratory, which is especially beneficial for those who work a full-time job or have a family to look after.

Cons of Online Training

The online nature of learning presents a few drawbacks as well, such as;

Limited Practical Training

Online learning does not offer adequate hands-on training, which is needed in the electrical field. Working on electrical systems requires precision and practice, which can’t be substituted by online classes. An exploration into electrical works such as troubleshooting, repairs and installations is highly recommended.

Limited Interaction with Professionals

Online courses may not offer feedback from professionals regarding your performance. While having an experienced electrician to lead you through a problem is a fantastic way to learn practically, online courses do not offer much guidance in this aspect.

Final Thoughts

Online learning is a fantastic way to learn, but it isn’t perfect for everyone. As an electrician, you need a balance of theory and practical experience. Electrical systems can be dangerous and cause unforeseen issues that a professional electrician should tackle. Therefore, it is incredibly crucial to have a practice experience and practical training.

Once you complete online training, it is advisable to look into apprenticeships. These offers access to professionals, practical training and real-world experience. It’s a perfect way to apply and improve the skills gained through online studying.

In conclusion, you can learn to be an electrician online. It is important to seek reliable accreditation, and courses that combine theory and practical training. Indispensably, practical training under the guidance of expert electricians will ensure you have the experience to handle real-world electrical issues. With this combination, you can learn to be an electrician and excel in the field.

Can I Replace A GFCI Outlet Or Should I Call An Electrician?

Can I Replace A GFCI Outlet Or Should I Call An Electrician?
GFCI outlets are a necessity for preventing serious electrical shocks and fires in the home. They are a safer option than traditional circuit breakers or fuses and can cut power in under 30 milliseconds to protect your health, property and family. These types of outlets are vital for many areas in the home, including kitchens and bathrooms where water may mix with electricity. However, a faulty outlet can be dangerous even when not in use, so it is always a good idea to have an electrician inspect your home’s wiring to ensure you have these outlets installed correctly.

What Is A GFCI Outlet?
A GFCI outlet is a safety device that protects people from electric shocks and electrocutions. It monitors the flow of electricity and shuts it off in case there is a ground fault or other electrical malfunction that could result in an electric shock. This kind of outlet is installed in wet areas, such as bathrooms, kitchens and garages. It is also required by law in new homes. In fact, water and electricity are a dangerous combination, so it is recommended that you install these outlets in all wet areas of your home.

How Do I Replace A GFCI Outlet?
Replacing a GFCI outlet is a home improvement project that many homeowners can do on their own with the proper preparation. It does involve some basic understanding of electricity, so those with limited knowledge should consider hiring a professional to perform the work. First, shut off the electricity to the old outlet by flipping the switch on the circuit breaker that controls it. Then, use a voltage tester to verify that power has been disconnected. Next, prepare the wires for the new GFCI outlet by labeling each one and stripping them to about three-quarters of an inch. Push the wires into corresponding holes on the outlet and give them a slight tug to make sure they are secure.

Can I Replace A GFCI Outlet Without A License?
A DIYer with basic knowledge of electrical wiring may be able to replace an existing outlet with a GFCI outlet, but only when swapping out a three-prong outlet—two plugin slots and a hole. Outlets with only two slots and no third hole indicate the presence of older wiring that should only be replaced by a licensed electrician. So while it’s not impossible to replace an outlet yourself, you should generally always hire a professional if you’re not familiar with how outlets are wired. The task is not particularly difficult, but it’s risky and can lead to serious injury if done incorrectly.

Should I Call An Electrician To Wire My Hot Tub?

Should I Call An Electrician To Wire My Hot Tub?

Many homeowners choose to take on the wiring themselves. They figure it will save them money and time. But hot tub installation is not really such a simple task, and it can involve all kinds of unforeseen details. In addition, you may even need to upgrade your electrical service to accommodate the increased power load.

Upgrading Your Electrical Service

When you buy a hot tub or install one, it requires a certain amount of power. Depending on how old your home is, it may not have the extra circuit breakers needed to accommodate this increased power load. That is why upgrading your electrical service is so important. This allows your new appliance to use the energy it needs safely and efficiently without tripping your breaker or burning out your appliances. If you are putting a new appliance in that will consume more power than your panel can handle, such as a hot tub or air conditioning, the entire service will need to be upgraded to accommodate this. This is especially true if the house was built more than 10 years ago and doesn’t have the required breaker space to accommodate your newest technology. This will also allow you to lower your insurance premiums and add value to your property.

The Potential Hazards

It’s best to leave the installation of a hot tub to a professional electrician. They are trained and experienced in wiring heavy-duty electronics like spas, and they know what to look for during the installation process to ensure your safety. In addition, they will ensure that your electrical system is in compliance with code requirements. For example, they will install a GFCI outlet to prevent any electrical shorts that could be harmful to anyone using your hot tub. Aside from that, they will also ground your hot tub’s wires to the earth in case of an emergency. If you don’t do this, then you risk the possibility of your hot tub tripping the breaker and causing a fire. Another common mistake is failing to bond the metal parts that carry current together and secure them to the panel. This can lead to electrocution if they’re not properly bonded, especially when touched by someone in the hot tub.

Call In The Professionals

A hot tub is a great way to relax and unwind after a long day. It is also a wonderful addition to your home and can be used year-round. But before you can enjoy the benefits of a hot tub, it must be wired correctly. The wires should run through a conduit, which can be buried under or above ground. And before you start digging, it’s important to call your city building department to learn the appropriate depth and location for your conduit. DIY wiring mistakes in this area can often pose a serious risk, exposing you to shock and electrocution if the improper wiring is not fixed. Therefore, as with any electrical wiring project, you should always hire a licensed electrician to help do it for you. 

How To Choose A Ceiling Fan Replacement

How To Choose A Ceiling Fan Replacement

When choosing a new ceiling fan, it’s important to think about where you plan to hang it. Will the ceiling fan installation take place in a living room or are you searching for the best outdoor ceiling fan to cool off things on your patio?

Getting Started

A ceiling fan is a simple design intended to circulate air, creating a cool breeze. Depending on the model, you may have a number of options for blades and accessories like light kits or a downrod. The first thing to do is decide what you want your new fan to do. Do you want it to be a main source of cooling, add extra lighting or simply increase the overall ambiance? Next, you’ll need to determine where in your home you plan to install it. Generally, fans work best in rooms where people spend a lot of time – such as living rooms and office lobby areas – and where the ceilings are relatively high. And before starting the project, you will need a number of tools and supplies. These include a screwdriver, voltage tester, wire cutters and wire caps.


The overall cost of a new ceiling fan will depend on the type you choose, the features and accessories you add and the labor you need to install it. The cost will also be affected by whether the existing wiring needs to be changed or if you want your electrician to run new wires and add a switch. If you need to change the existing wiring to support a ceiling fan, you will have to pay extra for this. The electrician will have to open up walls, run wires, and put boxes in place. It can be a big job that might cost up to $2,000.

Energy Efficiency

Whether you want to save money on your energy bill or reduce your carbon footprint, a new ceiling fan can be an excellent way to cut back. You just have to choose the right one. To find out how much a new fan will cost to run, first determine its wattage. Then, multiply that number by the cost of a kilowatt hour that your utility company charges. The resulting number should be close to zero. That means that it costs less than a nickel to run the fan for an hour, which is a good start. If you want to really save money, look for fans with high airflow efficiency and low electricity usage. That will mean that you don’t have to turn up the speed or increase the blade size to move more air, which will use a lot more energy.

Ask A Professional

It’s hard to beat the convenience of mounting your fan directly to your ceiling joists. To do so, you’ll need a specially rated hanger and box and a sturdy ladder or scaffolding. For the best combination of quality and price, you’ll want a professional to get the job done right. Fortunately, Walsh Electric is here to help. Our staff will provide you with an estimate and set you up with all the tools you need to install a top-of-the-line ceiling fan replacement in no time at all. You’ll also find our helpful staff available for questions and advice at your beck and call. So, let’s get started! You’ll soon be ready to tackle your upcoming project with confidence!
