If you are looking for a piece of mind when traveling to new places, hardwired surge protectors are the way to go.
The Progressive Industries one is the safe bet.
Surge protectors keep the electrical components in your RV safe from unexpected fluctuations in current.
It is necessary for lighting strikes, surges, faulty wiring, and other similar issues that can cause sudden current change.
Campers know that campgrounds offer have power fluctuations, because of improper maintenance and many people connected to the grid at the same time.
But, before we get into details with RV surge protectors, let’s break things down about RV power failures.
RV Power Failure: What can be the Cause
Almost all power failures in RVs are caused by one of the following four things.
If you park in the older campsite, there is a risk that the campground doesn’t have updated electrical wiring.
During the summer months, because of excessive air conditioning use, the risk of low voltage is even higher.
A power surge is a sudden and significant increase of power.
The most common reason is a lighting strike, and the symptoms are smoke, damaged electronics, and burnt wires.
When the live and neutral wires aren’t switched correctly, the electronics stay on the grid even after you turn them off.
Open Ground Outlets
Unprotected surges can happen when there is a defect to the current ground wire.
An outlet without ground connection can also cause it.
Portable VS Hardwired Surge Protection
RV users can choose between two styles of surge protectors.
Several factors such as convenience, ease of use, and safety determine the style for you.
Portable surge protectors go directly into the shore power electrical box.
They are compact, lightweight, and easy to use.
I like that the portable surge protector doesn’t require installation, so I can say it is a plug-and-play product.
But, you need to retrieve it and store it when you are leaving and plug it in whenever you reach the new campsite.
They go outside your RV, so there is a risk for theft.
You can try locking them to reduce the risk of theft.
The alternative is hardwired surge protectors.
They go into the electrical panel and look like a medium-sized black box.
You need to install them, and sometimes even hire a professional to do it properly.
Once installed, hardwired protectors require minimal maintenance.
Hardwired surge protectors offer continuous protection and are safe from weather and theft.
The Difference Between Management System (EMS) and Standard Surge Protector
If you are looking for a new RV surge protector, you are probably wondering about EMS and standard surge protectors.
The two differ by the level of protection and price tag.
EMS surge protector offers broader protection.
It protects against wiring issues, reverse polarity, low/high voltages, open ground and an open neutral connection.
RV Insurance Policy
I always advise RV owners to maintain insurance coverage for their campers.
However, many insurance policies don’t cover the power surge events and potential damage to RV electrical system.
Therefore, it is always advisable to check with your chosen insurance company to clarify the options about electric damage.
If the insurance policy doesn’t cover the surge damage, a quality surge protector is a must.
Features to Look for in a Surge Protector
Here are the best features to look for in a surge protector.
Reverse Polarity Detection
This feature protects you against poor electrical wiring.
However, if you are staying in the campground, you are unaware of the electrical wiring work.
Therefore, reverse polarity detection is a safe option for traveling.
The most common problem occurs when neutral and live wires connect to opposite terminals.
The consequences can be severe damage to electrical appliances.
When the grounding wire isn’t installed properly or damaged, a protector won’t work.
Therefore, before you rely on a surge protector, check the open ground error.
Accidental 240V Connection
A 120 Volts outlet is the most common in the United States, but some appliances need a 240 Volt supply.
Those are clothes dryers, stoves, electric cars, ovens, etc.
When you accidentally plug your motor home into a 240V without a surge protector, you risk excessive and immediate damage to your electronics.
AC Frequency Monitoring
EMS surge protectors monitor the AC frequency and keep your system safe from deviations that are too far from 60Hz.
It is practical touch for traveling around the country because older campsites have an unstable frequency.
Some surge protectors come with LED displays to monitor error codes.
Others include indicators.
In both ways, it is useful to know what the problem is.
Error Code Recall
Memorizing past errors allows you to understand what happened to your power supply system while you were absent and prevents future troubles.
Things to Consider When Buying a Surge Protector
Let’s check the most important things you need to analyze before you buy your surge protector.
30 Amps or 50 Amp
Amps measure electrical current, and there are two systems – 30 amp and 50 amp.
The amperage depends on the size and electrical requirement of your appliances.
Smaller RV usually have 30 amps systems, while large ones with multiple appliances such as invert AC, refrigerators, etc. have 50 amp systems.
If you have a 50 amp system and you plug it in a low voltage 30 amp max power source, you can destroy the system and cause burns.
So, a 50 amps surge protector works with a 50 amp RV power supply.
The same applies to 30 amp surge protectors.
In most cases, every surge protector has manufactured both systems.
The Class and RV Size
The larger the camper and the larger the electrical use, the greater the need for electrical protection.
People with a class A or C motorhome, or fifth wheelers are advised to choose the EMS system, because of the advanced protection.
In most cases, large motorhomes have high-end electronics, so a surge can cause a lot of damage.
The Camping Location
Electrical power supply quality differs across different campgrounds.
Modern campsites have professional installations that reduce the risks of a power surge.
Older campgrounds haven’t been maintained, so there is a high risk for potential damage and problems.
If you camp on few locations that prove to be safe, you can pick a standard surge protector.
If you like to explore and park in older campgrounds, an EMS surge protector might be a better choice.
There are good and bad sides to hardwired and portable surge protectors.
To sum up, let’s go briefly through them.
Hopefully, you will be able to decide which style is for you.
Portable Surge Protectors Pros:
- Simple plug-and-play operation
- Suitable for outdoor use
- More options on the market
- Cheaper than hardwired
Portable Surge Protectors Cons:
- High theft risk
- When not plug in, you need to find a place to store it
- You must plug it on every trip

Hardwired Surge Protectors Pros
- Easy to use
- Better security
- Maximum protection against different issues
Hardwired Surge Protectors Cons

Don’t wait until your fridge or TV gets fried to get a surge protector.
Prevent it whether by choosing a portable or hardwired unit.
The choice is totally on you.
Remember, even a cheap portable, one-time surge protector is safer than traveling without one.
