I am sure you have RV friends who never seem to experience power surge issues but anything could happen.

Mis-wired shore power pedestal – it is inevitable that non-certified electricians are usually hired to wire up the power pedestals at the RV parks or campgrounds.

If one of those electricians doesn’t know what he is doing, all it takes is one mistake on his part to cause instant damages to all the electrical appliances or wiring inside your motor-home.

Defective power pedestal at campgrounds – it is definitely not uncommon to chance upon power pedestals that have issues like no neutral, reverse polarity and no ground.

Such issues will again cause unexpected damages to the electrical equipment and built-in appliances inside your entire rig.

Poorly maintained power outlets – some of these power outlets which lack maintenance may cause under-voltage, over-voltage problems that cause your appliances to operating below or above their usual operating voltage allowance.

Disclaimer Note: This Fact May Shock You!

Most RV surge protectors are NOT going to provide much of a protection to your motor-home.

So what’s the core difference between a typical surge protection device and one that comes with built-in electrical management system (EMS)?

Well, as obvious as it may be, a typically good surge protector protects a power surge, e.g. huge voltage spike especially from lightning and some basic fault indicators. And that’s about it.

Such devices will NOT protects you from anything else like harmful effects from defective power pedestal (an open ground, open neutral or reverse polarity), mis-wiring, high and low voltages and so on.

On the other hand, RV surge protectors (Portable & Hardwired) that come built-in with EMS will provide your RV with features (depending on the brand and model you get) like:

  • Over/Under Voltage Protection
  • Reverse Polarity|Open Ground|Open Neutral Detection
  • Reverse Polarity|Open Ground|Open Neutral Protection

What We Think?

Although this 35550 model is almost as good as those from Progressive Industries, we do not quite like that fact that we have to fork out additional cash just to get the remote LCD display feature which may not make sense for most RV owners. Since it is a hardwired surge protection unit, the remote LCD display should be given by default. Another thing that concerns us is that there is absence of protection against plug and receptacle overheating. Beyond that, we still think it is a worthy buy for RV owners who are out on the road most of the time

Should I get Portable or Hardwired Surge Protection Device?

As you may already know, portable RV surge protectors are simply plug and play. And there is zero hassles although you will have to plug it into the park pedestal whenever you are.

There are absolutely no requirements for electrical skill and knowledge at all.

Whereas for hardwired type, you may have to either possess electrical skills or pay extra cash for someone to wired it into your RV for you.

And obviously you would not run the risk of the surge protection device getting stolen.

Hence whichever you choose, it should all boils down to whether you are technically trained or you would rather get the portable ones and have it plugged in wherever you are.

Bottom Line – Which One Should I Really Get?

Progressive Industries and Surge Guard (Southwire) are two of the most popular brands in U.S. and their customer service is really top-notch. Not to mention the lifetime warranty they provide for most of their products.

I personally would go for one from Progressive Industries if I really have to choose one.

Have you ever calculate the amount of cash you have to fork out should your entire RV get burnt up?

This should include all the expensive furnishings and electrical appliances inside your RV.Progressive Industries
