Types of RV protectors

1. Hardwire

This one is built into your power system. The advantage of this type is that most have a bigger capacity compared to other types of protector. On the flip side, in case the protector melts or burns out, you will not have power in the RV until you replace your surge guard.

2. Portable (or plug-in surge protector)

Unlike the hardwire surge protector, this one can easily be plugged in or plugged out and is very easy to replace however they can easily be stolen or you can forget to carry them during your camping trip.

What to look for when buying an RV surge protector?

Amps Rating

Amp is the quantity of electricity present in an electrical current. Ensure that the amp rating of the surge you purchase is compatible with that of your RV. A 30 amp guard is made for a 30 Amp 120-volt outlet while a 50 Amp is designed for a 50 Amp 240-volt outlet. Note that a poor choice of an RV surge guard increases the risks of overheating and fires.

Joules protection

This is the level of protection you get whenever there is a surge. If a surge guard has a high joule rating, it means it can withstand a high amount of electricity. A good surge protector should protect you against power surges, low voltage, miswiring, and improper grounding. The most important aspect of the protector should be how fast the surge protector cuts off electricity supply in case there is a danger. If your main concern is protection against lightning or protection for sensitive electronic devices, then a surge with high joules rating would be the most ideal choice for you.


Look for a guard with a display that is easy to read and understand. A well-elaborated surge will enable you to easily detect any issue that may arise. Most of them will include flashing lights and indicators to alert you when a problem arises.


Electricity is nothing to mess around with. Go for a surge guard that has a simple and easy to understand installation instruction menu.

Power management

Some high-end surge protectors include a power management system that will shut the whole system for you should there be a problem.


Very heavy surge protectors will slow your RV down or, it may not fit in your utility closet.


If you are on working within a tight budget, go for a guard with just the basic features that you need. But, if the price is not a constraint, go for quality, and convenient one with all the protection features possible


Some fans in certain models produce more noise than others. Also, some models have flashing lights and loud alarms. If noise is an issue for you, go for ones that have padded feet and with less noisy alarms.
