Where Do You Install An RV Inline Surge Protector?

Camping is fun but when you’re bringing electric-powered devices, there’s always the risk of surges, overloads and shortages due to the sometimes unpredictable power supply available in parks and campgrounds. This can lead to damage in electrical equipment. Using an RV surge protector is a good idea since it will protect electrical systems from overloaded circuits and a faulty power supply. But where do you install a inline surge protector in a RV? Portable units are handy and lightweight but can be easily stolen. A better choice would be something that’s hard-wired and has been partly installed.

How To Choose RV Surge Protection

Power needs vary greatly, depending on usage and number of electrical equipment used. To find out, compute the maximum number of volts you will likely use and then buy according to your needs. Newer RV units use circuit boards for major electrical systems built into the vehicle. With other added personal gadgets thrown in, the power requirement increases significantly. Devices are generally hardwired to the coach, generally in 30- to 50-amp sizes. Thirty-amp models can generally handle a maximum of 120V while 50-amp units can manage 240V. Some models may come with amp monitor displays, although a more basic model that uses led light indicators to show it’s working will often suffice.


Hardwired surge protection for RV gadgets should be performed either by a professional or a skilled DIY person, not by a novice. Installation consists of mounting the gadget at the output terminals with an electric wire running from a converter. Next, the power surge protector is plugged into the pedestal at the campsite while the power cord is plugged into the input terminal. If using portable devices, these can be placed and plugged outside the vehicle, although this makes them easy to steal. With the gadgets on board, monitoring the device and amps cycling will be much more convenient. A unit performs a test prior to turning the converter on in order to ensure that there is sufficient energy for the system to use. The device can also shut down the system automatically if an overload or a shortage is detected. Once levels are back to normal, the device can then run the system again.

Types Of RV Surge Protection

What matters most in choosing RV in-house protectors is the individual’s specific needs. A tech-savvy person will want a unit that allows him or her to monitor amps and other information on built-in displays while someone who prefers the most basic function will find a simpler setup easier to use. Other than the necessity of an RV surge protector, ease and comfort of use should be a major consideration. There is also another type of home surge protector that may be useful to many RV owners. The portable surge protector with ground offers extra protection against power fluctuations that are so common in campgrounds. A grounded surge protector offers extra safeguard against any risks that may be caused by plugging into unreliable power sources. Without the extra security measure, sensitive gadgets can easily be damaged.

There are also power surge protectors that are especially designed for mobile internet devices. Since the unit uses the energy source from the campground and stores power in the RV’s battery, there is little inconvenience of a downtime. To ensure a consistent power flow in your RV, consider using a polarity checker for testing the AC power in the campground. It’s cheap yet offers the convenience and security you will need.
