How To Choose the Best RV Power Surge Protector?

As an RV owner, you will definitely need to buy the best RV power surge protector if you need to protect it and its appliances from any surges and spikes in voltage. Without a power surge protector, appliances will experience damages that will need you to spend much on repairs. This, you do not want.

Being a newbie, you may not have any experience with surge protectors therefore making it difficult for you to make the right purchase decision. There are several important factors that you need to consider to enable you buy the right surge protector for your RV.

30 Amps or 50 Amps?

This basically means the type of electrical supply on your RV. Is your RV 30 or 50 amps? This is an important factor to consider. The surge protector you plan on buying has to match with the electrical supply needs of your RV.

A good surge protector, whether 30 or 50 amps should ideally protect your 50 amp RV conveniently and vice versa. You can easily differentiate the two using the prongs. A 30 amp has 3 while a 50 amp has 4.

Hence, after identifying if your RV is 50 or 30 amp, you can now comfortably buy a surge protector that perfectly suits your RV and the appliances present in it. Failure to do this may lead to false connections which will cause damages eventually.

Portable or Permanent Surge Protector

Mainly, there are two types of surge protectors; either portable or hard wired. Portable protectors are those that are easily mobile, in that you can move them from one place to the other. On the other hand, hard wired surge protectors are permanently installed on your RV’s compartment.

Nowadays, portable surge protectors are more popular among RV owners in comparison to hard wired ones. This is because they are easy to install and replace altogether. You do not need to have any electrical knowledge so as to install it. Their main downside is that they may be exposed to harsh climatic conditions.

Hard wired surge protectors are usually more expensive but are efficient as well. Moreover, they do not face exposure to tough environmental conditions such as rainfall and UV rays.

Easy to Install

Who needs a hard to install surge protector every time they need to embark on a journey with their RVs? You certainly need to get a surge protector that allows you an easy time to set it up and begin usage immediately. Most portable protectors install with much ease unlike the hard wired ones.

Hard wired protectors undergo a complicated process just to install and you may need an experienced technician to make this possible. Failing to install it correctly may lead to dire consequences.

Also, it is essential to make sure that the device you are about to buy comes with a clear set of instructions that eases the installation process. Do not buy something that needs the input of more than one person. You might be alone in the wild and do not know how to install.

UL Certification

A surge protection that features UL certification is more reliable as they as it is proven safe and secure for use by RV owners. If you need to ensure that your appliances are highly safeguarded, then get one that has UL certification. Such surge protectors have undergone frequent testing by experts and have passed such safety tests.

To achieve high performance and excellent output, a UL certified surge protector comes in handy. Those that do not have this kind of certification may greatly disappoint you and cause lots of damages therein.


Normally, budget is a personal decision. It depends on how much you are ready and willing to spend on a certain device. Surge protectors have different price ranges depending on size and the features they possess. Most efficient protectors may cost between $150 and 300$.

Anything costing below $100 may not be reliable. As the saying goes, cheap is expensive. Buying a cheap surge protector may cause a lot of damages which forces you to incur greater costs for repairs. Either way, get a surge protector that is economical but still delivers optimum performance.

LED Display

The LED display on a surge protector clearly outlines important information that you need to know about your RV’s electrical system. Most importantly, it has to be easy to read and understand. Something you do not understand will not quite make sense to you.

Their main function is to caution and indicate any dangers that may occur to your RV’s electrical system. The different lights on this display will indicate issues such as faulty wiring, reverse polarity, open neutral, open ground and high or low voltage among others. Thus, you need to familiarize yourself with the contents on the display.
