All You Need to Consider When Buying A Surge Protector

Surge protector’s main role is to protect your RV’s electrical appliances and other electrical things you may have. Power surges do happen, and they can damage the appliances that you have on your rig or your entire electrical system. To solve this problem, purchasing a surge protector is important.

A surge protector is a device that you would have when you are traveling on the road. You will never know when a power surge may happen, so in order to prevent this problem, purchasing a surge protector is the best way to go. All full-time RVers may rely a lot on the limited appliances that they have, so buying a reliable surge protector is crucial.

30 Amp Vs. 50 Amp: Know the Amperage

The amperage is the main thing that you need to pay attention to when you are buying a surge protector. There are two versions when it comes to amperage, which are 30 and 50 amp. It is important that you must get the right one for your RV, and it is easy to figure out which one you would need.

All you need to do is look at your rig’s power cord. If you see three prongs, you need to purchase a 30 amp surge protector, which is typical in smaller campervans. If you have a power cord with four prongs, you would need a 50 amp which is mostly found in most motorhomes.

The Joules Rating and Power Rating

As you may have noticed above, I have mentioned joules ratings which essentially tells you how much protection the surge protector provides your rig. A surge protector would disperse heat in the event of a power spike. The highest the joules rating is, the more effective the device is at prevents any overheating. The joules protection becomes important when you are looking for devices that have a longer lifespan and fuller protection.

On the other hand, the power rating is rated above the maximum energy level that your rig will generate. You need to make sure to consider all the appliances that you regularly and concurrently have in your RV.

Diagnostics and LED Display

Now, surge protectors have evolved to be sophisticated, and modern versions use diagnostics to detect any issues that the protector may have in the power supply. When there is a problem, the protector will alert you if there are any problems. This feature can come in handy when you are visiting new campgrounds with unknown power supplies.

When the surge protector detects any irregularities, the LED display will come in handy because it will let you know what’s the problem. The LED display should be easy to read and should be bright enough for daytime use which is one of the issues that some surge protectors have.

Types of RV Surge Protectors You Need to Know

There are two types of surge protectors that you would need to know when you choose your surge protector.

Basic surge protectors. These surge protectors are as basic as they can get; just like what the name suggests, it is a basic device. They can protect your rig against unstable electricity at RV parks or campgrounds.

Complete surge protectors. On the other hand, these devices offer a higher level of protection and come with a higher price tag. Some surge protectors come with electrical management systems that bolster RV protection. The protection includes things like faulty wiring, high and low voltages, and open ground.

Power Strip. The best thing about this surge protector is that you can easily plug it into an electrical outlet. It also has several unique outlets, which makes it possible for you to plug several appliances into it.

Hardwire. Hardwire surge protectors can conveniently and firmly attach to the internal parts of your rig. This type of device is often available in a specific compartment where your wiring takes power. One of the advantages of this device is you can stay connected at all times. It will eliminate any worries as far as safety and protection are concerned.

Portable. If you don’t want to deal with the hassle of installing your surge protector, then it is best to go for the portable type. This is easy and convenient to use since it doesn’t need any complex installation process. All you need to do is connect it directly into an electrical pedestal’s outlet, and you are good to go.

It is best to purchase the complete surge protectors, which will provide much more comprehensive protection than the basic ones.

How an RV Surge Protector Work

The primary purpose of an RV surge protector is to offer assistance every time you plug your vehicle into an unfamiliar or unknown power source. These sources can be a friend’s home, RV parks, campgrounds, or a storage unit. It works by analyzing the power source to figure out if it is neutral or a proper ground.

It prevents any issues that are related to reverse polarity and low as well as high voltages. You can expect it to work in monitoring any changing situations such as low and high voltages as well as surges. Surge protectors also function similarly to the ones that you use for your home electronics.

Now, the main advantage of using a surge protector for your rig is that you can conveniently plug it into a power pedestal at specific RV sites without worrying. Some also feature a kit that you can use when it comes to wiring the surge protector to a primary power feed directly.

Another great function of the RV surge protector is it examines power sources such as proper voltage, neutral condition, grounding, frequency, and reverse polarity. It also works by constantly keeping track of power situations that you might encounter along the way.

Lastly, a surge protector also ensures in case of certain changes, and the device will immediately cut the power of your rig. It can offer protection for your expensive devices and electronics by preventing any costly damages to them.

Final Thoughts

Purchasing a surge protector is a great investment since it is necessary for your safety on the road. In my opinion, the best choice for a surge protector is the Camco RV Defender because of the joules rating and other features it offers. It also has an automatic shut-off, which is great for saving my appliances in my rig. With all the options that you have above, it is up to you to choose which one will be the best fit for you!
