Best RV Surge Protector | Top 5 Best RV Surge Protector Reviews

The right RV surge protector for you can be found in this post because you are given options based on what you need.

Having an RV and using it for traveling entails that you have to use several sources of power, and those sources have to deliver good power. This means that it doesn’t have faulty grounds, has the right frequency, legs are not disconnected, and the voltage is just right or maybe it has a neutral condition. You can be like others and carry the voltage meter, but that does not give enough protection because the condition can shift while it is plugged. The best thing you can do is to use an RV surge protector. There are RV surge protectors given in this post to help you pick the best.

Things to Look for When Selecting Surge Protector

  • Size

To get the right size, check its Amp rating first. What is indicated on the surge protector points out the kind of power you will most likely use when you plug your RV. One option is to get an adapter to use the input power when you are at a park where you don’t have enough power supply. Although, you should not get a large or small amperage and constantly adjust the power by using adapters. Pick a surge guard that is appropriate for your application and this is going to lessen the risk of overheating, fire, and other electrical problems.

  • The rating

You need to observe the protection rating and the measurement comes in joules. The most popular way of rating the amount of protection is to check the rating of the joule. When there is too much energy because of spikes or wrong supplies try to enter the coach, the Surge Guard does its job and dissipates the additional energy into heat, and this is to protect you from any danger that may occur.

  • The type of surge protector
  • The first kind of RV protector is only a surge protector. It will plug into the power of the pedestal found in an RV site and it’s been programmed to give protection against large surges. It gives protection against lightning strikes, and that’s all. It does not give protection against shifting voltage conditions nor faulty wiring detection. The basic surge protector is better than not having anything, but it will not help with electrical problems other than big voltage spikes like the ones that come from lightning strikes. There are two models for this: 30 amp and 50 amp. It is ideal to buy the ones made by known brands because they already have a good record for their warranty and customer support.
  • The second kind is the basic protector that comes with an indicator for faulty wiring. These indicators are good because you don’t have to plug your RV into a pedestal that has a faulty wiring or has been damaged and could shock you. These are an upgrade from the basic one, but they also don’t have protection against shifting voltage conditions. 30 and 50 amp models are also available for this.
  • Complete protector for RVs is the third type and these protectors can prevent damage caused by large spikes in voltage, high and low conditions, as well as faulty wiring. Since majority of the electrical damage comes from low or high voltage conditions instead of power surges, and this is the best kind of power surge protector to buy. They cost a lot more than the first two, but they have more features.

Surge protector safety precautions

  • Use RV surge protectors indoors and only in dry locations
  • Make sure that you don’t exceed the surge protector’s electrical rating
  • Do not use the RV surge protector with aquariums or other products associated with water
  • If a power cord comes with the surge protector, unwind it before use and make sure not to cover it. Do not allow your pets to go near the power cord
  • When you are using a surge protector with devices like power tools or other appliances, make sure that the amperage requirements of the device is met and will be able to take the current that the device is using

Inspect the electrical system

  • Begin inspection with the electrical cord that is used to connect the RV to the power source at the park. Check if there is 20, 30, or 50 amps and if the park offers the amps you need. If the system has 50 amps, make sure that you use a step-down cord to lessen the amps from 50 to 30
  • Inspect the cord if there are any damages, cracks, breaks, and cuts where plug can be connected to the cord, crumbling or a feeling of stickiness is an indicator of serious wear
  • Check if the plugs prongs are secure and intact, or if they are wiggling. See if they are bent and if the ground prong is intact

Fuse boxes and circuit breakers

  • You should know where they are
  • See if there are marks to indicate what they are controlling
  • Try to see if it is a replacement breaker of fuse
  • Are corrosion signs or deterioration?
  • Inspect if they need to be repaired
  • Check if all of them are working properly
  • The breakers have to be flipped on and off

Before you plug the RV at the park

Line voltage – Buy and use a line voltage meter or gauge, and also a tester for polarity. These do not cost much and will warn you before damage happens.

The polarity tester should be used for checking the shore power before plugging anything into it. There is a light system in the polarity tester that will indicate if the shore power has faulty wiring so you can go to another site.

When it is already plugged in, check the inside of the outlet to make sure that the line voltage belongs to the safe zone, which is between 105 to 130 volts. You can leave a voltmeter with three prongs in an outlet so it will keep on monitoring and will remind you that it needs to be often checked.

Preparation for emergency

You need to have candles, flashlights or lanterns. If there is the moon, it is almost impossible to perform repair inside or outside. Together with additional fuses and circuit breakers used as replacements, surge protectors might be able to save your system from any electrical fluctuations in the park. It is wrong to think that just because your 30 amp RV is connected to a 50 amp power source, it can be used to run any appliance. There is still a limit of 30 amp.

You were given safety precautions so that you’ll know how to take care of the RV surge protector you are going to buy. Choosing from any of the products is one thing, but knowing how to take care of it is another consideration. Remember that spending a little on a surge protector can save your RV and sometimes it can keep yours from danger.

The products listed are my top choices because I have been using RV surge protectors for years and I am equally happy with any of them. The product you will choose among the best surge protectors above depends on what you need. Make sure to check them out, especially if it is your first time to buy because you will not end up being disappointed.
