How Does A Surge Protector Work?

Ideally, the more joules of protection the surge protector has, the better it can perform. For example, the unit has the capacity to give 1,000 joules of protection; then it is able to withstand about 1,000 joules attacks.

There are several factors that can increase the voltage of electricity, such as when the electric potential energy lasts for about 1-2 nanoseconds, which creates a spike, and when the increase in voltage lasts for 3 or more nanoseconds, thus creating a surge.

When there is a high amount of spike or surge, it can potentially damage an electrical device. Basically, a wire will "burst" when the electrical pressure is extremely high. In case your equipment survives the increase in voltage, the surge can still wear it down eventually, as the surge can put extra pressure on the components.

Is It Necessary To Use It?

Your RV is basically your mobile home that contains lots of electronics and wires. Whenever you park it in between your journey, you connect your vehicle to a park power pedestal.

When something goes wrong with that external power, it can adversely affect your electrical devices and damage your RV. Thunderstorms, too low voltage, too high voltage, faulty connections, are common reasons for fluctuations and spikes.

Electrical systems that have been damaged are a costly affair, not to mention that irregularities of power can fry your motor home.

While the power that you get from the park or campground is beyond your control, there is something you can do to regulate the power and protect your vehicle and gear from damages by using the best RV surge protector.

What They Can Also Do

You can say that surge protector is your first line of defence, once it is installed between the power line and your RV. Note that it is available in portable units as well, but the idea is still the same.

Besides from being your shield against bad power, they are also smart and sacrificial. They have the ability to cut the power when they face electrical problems. The smarter ones are designed to do this.

With regard to sacrificing themselves, they can do it if they cannot shut off the power. Instead, they allow themselves to get fried and force to cut power in case of major power crisis.

Let's hope that it never gets to that point, but in case you find your surge protector get fried, it means the unit saved you and your vehicle by sacrificing itself.

Types Of Surge Protectors

using surge protector

These two types of surge protectors are both recommended. You simply choose what works best for you:


To be able to use this unit, at first, you need to hook up to a power pedestal, and then plug your RV. There is no need for any wiring works in order to plug into an electrical pedestal. No installation process is needed. A portable unit can perform well in any weather conditions.

Remember that when using portable surge protectors, they can easily get stolen. You may use locks to prevent this. Also, if the pedestal you are hooking up is a bit short, a portable unit can drag on the ground.


This type is more compact than a portable unit. Using this type of surge protectors means you need to hardwire it inside the components of your RV. Basically, you look for the wiring, typically beside the power reel, to draw power from the electrical pedestal outside.

Considering it is positioned inside your vehicle, it removes the problem of getting stolen or leaving it behind.

However, it requires correct wiring job to install it; otherwise, you find yourself doing some additional work if it gets fried and needs replacement.

What To Look For

Amperage Rating - The amperage rating of the surge protector should be suitable for the electrical system in your RV. It is the current that runs through the appliances in your vehicle. The two types of amperages are 30 amp and 50 amp. Buy 30-amp surge protector if you have a 30-amp rig.

If you are using a lower electrical footprint for your RV, a 30-amp unit is good enough. If you are using many appliances in your RV, you might need a 50-amp protector. Having said that, it is possible to hook up to a 30-amp pedestal even if you are using a 50-amp protector. Simply use an adapter plug to attach the two protectors.

Features of the Unit -  When buying your surge protector, look for these features to help protect your appliances from all sorts of power failures. The unit should have protection from:

  • Low voltage
  • High voltage
  • Open ground (or neutral)
  • Accidental 240V plug in
  • Time delay
  • Reverse polarity

Manufacture Guarantees - This is also an important factor when buying the best RV surge protector. Choose the one that confidently stands for what they are offering to the consumers. They should have good customer service and a lot of satisfied customers backing them up.
