If you live in the United States, you’re likely well-familiar with our typical wall-socket setup. Your plug has two flat pieces of metal roughly half of an inch wide, with one side sometimes being slightly wider than the other. Your wall socket has two slots that match this, with one side also being slightly larger than the other. However, sometimes there’s a variance: some plugs have a third prong below and between the normal two, and most electrical sockets also have a third hole to match this plug. What’s the difference between these two types of plugs and is one better than the other?

To put it simply, yes, one is better than the other. When it comes to electrical plugs, the old adage “less is more” does not apply—the three-prong plug is far better than a two-prong. To learn why, let’s discuss the difference between the two.

In order for electricity to flow, you must complete a circuit. A circuit essentially is a connection from your power source to the device, and then from the device back to the power source. The line that brings power from the power source to the device is called your “hot wire”, which is most often red and comes off the positive terminal (noted by the large “+” sign). The line that then returns from the device to the terminal, usually a black wire connected to a “-“ sign, is known as the “neutral wire.” A plug must have both of these lines in order to work.

However, the third prong in a three-prong plug is a “ground” plug, which dramatically improves safety. When an unexpected burst of electricity happens, such a short in the device or a surge from your power supply, the ground plug will take that abundance of additional electricity and move it away from the device and down into the ground where it is safe. This prevents your device from being overloaded which can cause overheating, sparking, and fires in addition to ruining it.

Three-prong plugs didn’t become the standard in homes in North America until the late 1960s. If you have a home that was constructed around this time or after, odds are your wall sockets are probably already of the three-prong variety. Two-prong plugs can work with three-prong sockets just fine, and you’ll rarely experience any issues.

However, if you have any old two-prong plugs, you’ll likely need your electrical system updated in order to upgrade to a three-prong setup. Properly installing ground wires can involve several hours of electrical work and even cutting into your walls in order to do so properly, so it’s a rather large undertaking. However, it’s by far the safest and most prudent option.

Another option that doesn’t involve tearing open your walls is to install a ground fault circuit interrupter outlet, otherwise known as a GFCI. These sockets are two-pronged, but feature a miniature circuit breaker that measures the resistance through a plug and mechanically shuts off when the risk of a shock is present. While this can help you avoid being shocked by a faulty device, there is still no ground wire present so your electronics are not protected from a power surge.

Warm weather makes it more appealing to be outside after the sun goes down, and do-it-yourself lighting projects can add a distinctive flair to outdoor gatherings. Mr. Electric® has ways to power your tomorrow and help make your backyard the place to be on summer evenings with these great DIY backyard lighting ideas.

This inventive project uses a small can, a thrift-shop vase and a wooden stick to create outdoor lighting that looks store-bought. It requires a few simple tools, but is very quick to put together. Real or battery-operated candles inside the vase will cast a dreamlike glow across your yard. Try making a few of these and lining a sidewalk or porch with them.

Recycle old wine bottles by making a mosquito-repelling torch. All you need is a bottle, washer, wick, and citronella oil. You can add decorative stones or rocks to the bottom of the bottle to decrease the amount of oil you need. This can also help weigh the bottle down if you are worried about stability. Place the torches around the backyard where the flame won’t be blown out.

This project turns recycled cans into lanterns that can be painted and hung outside. Some of the steps require extra time, so plan ahead. Lanterns are a simple way to add color and light to your backyard or porch. Not only are they fun and easy to make, you can customize the paint colors and design to fit the atmosphere you want.

This is a simple project that can add lots of character to your yard. All you need is an opaque glass light shade and a string of lights. The string lights can be coiled inside of the shade and when placed around the yard, add a muted glow. They are also simple but striking decorations during the daytime. A benefit to this project is that the orbs are easy to reposition throughout the yard. Invest in a few extension cords to make sure you can put the lights exactly where you want them.

From the 1950s to the 1980s, the Federal Pacific Electrical Company (FPE) installed electrical panels in millions of homes across the country. Unfortunately, these electrical panels are basically recipes for disaster—over the years, electricians and home inspectors have found that FPE panels often fail to protect homes from overcurrent or short circuits. The danger seems to happen randomly: even if panels have been installed and working properly for years, a single incident can quickly cause the panel to overheat and create a major fire hazard.

Remember—circuit panels trip in response to unusual surges of electricity. If they fail to trip, as FPE panels often do, those electrical surges cannot be stopped or shut off manually and will move through your home until they run out of fuel or until the wires burn out. This could cause the panel to overheat and catch fire, leading to a potentially serious disaster.

FPE panels may not be up to modern safety codes – electrical safety standards have been updated significantly since the 1980s, and experts say that FPE panels, which were produced from the 50s and into the 80s, do not meet these updated standards. Some of the deficiencies noted by home inspectors include:

FPE panels may have serious design flaws – not only do FPE panels not meet modern safety standards, but they also came with some serious design flaws that weren’t even common among panels built around the same time. Some of the most significant flaws include:

FPE panels may have manufacturing defects – as if that weren’t enough, the Consumer Product Safety Commission (CPSC) has noted a number of defects that make FPE panels unfit for homes, including weak materials used to construct the breakers that may prevent them from tripping and could cause the panel to catch fire.

If you live in an older home and you’re worried your panel might be a danger, call Kolb Electric. Our trained electricians are familiar with the potential hazards of FPE and other outdated panels and can replace your existing panel with a modern panel that will keep your home safe for decades.

This months roundup post is for the month of November, 2016. It’s been a crazy month, but nonetheless; happy thanksgiving!

This month has been filled with tons of crazy news, and we are about to share it all with you in this months LED lighting link roundup. From insects and LEDs to towns and cities retrofitting their streetlights, we are going to cover these and many more in this edition.

Now… Here is the third addition of A Month in The LED Lighting Industry Link Roundup…

Several Cities Convert To LED Streetlights In Conservation Efforts

Listen (or read) in on this conversion where they talk about cities that have made the conversions, what it has done, and who is planning to convert next. It’s exciting stuff to hear about all of these cities making the conversion, especially since they are all saving money and producing better light.

East Lyme to begin retrofitting streetlight with LEDs

This town is making a smart move by retrofitting their streetlights throughout the town. Not only will they save in energy consumption reductions, but they will also reduce initial investment costs by Insects and LED Lights New Research

How are wildlife and insects affected by outdoor LEDs? This *video* goes over the topic, and how they may be affecting insects specifically.

LEDs Light Up Indoor Farming and Marijuana Cultivation

Marijuana growing is becoming a huge industry, and quickly too. LED technology is making growers be able to turn a better profit all while growing better crop.

LEDs come in rainbow colours

A new way to achieve various vibrant colors is making it cheaper and more efficient to do so. Learn how it’s done by reading this one!
