Protect your investment

If you aren't using a surge protector, you're taking a big risk. While spikes caused by lightning can damage your electrical system and appliances, there are common electrical issues that can be just as dangerous. Choosing a surge protector with advanced features will help you protect your RV.


Smart Surge Protection

Electrical problems are not uncommon at campgrounds, especially ones where wiring was originally installed decades ago. When a campground is full on a hot day and everyone is running their air conditioners, low voltage may cause a brown-out situation and damage your RV appliances. On the flip side, faulty transmission, bad wiring, or spikes caused by other RVers connecting to a shared line can all lead to voltage issues that may not be significant enough to trip a basic surge protector.


Power Watchdog surge protectors with Emergency Power Off are equipped with computers that monitor voltage and disconnect when voltage is at risky levels. Plus, they automatically reconnect power when power returns to normal. This keeps your RV safe from problems caused by low voltage like motors overheating in fans and air conditioners.


In the event of a major spike, you can replace the surge protection module itself rather than the entire unit. The modules are plugged in without soldering, so you don't need to be an expert electrician to make an easy repair. In fact, the only tool you need is a screwdriver.


Information at Hand

The Power WatchDog smartphone app

The Power Watchdog app lets you connect to your surge protector via Bluetooth. You can monitor your energy usage, making it easy to diagnose any ongoing energy issues you may be experiencing. When voltage increases or decreases to risky levels, you will be notified right away. You can also reset your surge protector without stepping outside.

  • Do 2024 Kia Telluride's Come With A Trailer Hitch And Wiring Already Included
    Kia Tellurides are in our install shop all the time for hitch and wiring installs since Kia typically will not install them at the factory. Manufacturers use "tow package" as a buzz word to charge you more typically so you'll want to get explicit descriptions of what is included with the vehicle. If it doesn't come with a trailer hitch then you can install the Curt Trailer Hitch Receiver # C13420. For wiring you would first need to install a 4-pole wire harness like the Curt Powered Tail...

  • Installing Power Watchdog 50 Amp
    Hi Tom, I reached out to the manufacturer of the Power Watchdog Surge Protector with Bluetooth and Emergency Shut Down - Hardwired - 50 Amp # HU27FR who said they need to be installed between your power cord and the transfer switch. They said the inputs and outputs are labeled on the terminal block and be sure to follow that. I have also added a link below to a video of an install we did which I hope is helpful.

  • Can The Lights Of The Hughes Autoformers Watchdog Surge Protector Be Dimmed
    Hey Sean, The Hughes Autoformers Adhesive Dimmer Shade # HU28VR is exactly what you need. This shade just has a 3M backing to stick to your Watchdog Surge Protector # HU67FR (30amp) or # HU87FR (50 amp) to dim the LED's to something more acceptable. This would also work for the hardwired versions (30 amp # HU77FR and 50 amp # HU27FR ) if you have them in a spot where the light could potentially be an issue.

  • Does 50 Amp Surge Protector Offer More Protection than 30 Amp Surge Protector?
    The Hughes Autoformers are certainly the deluxe of all the power protection products. On top of all the low-voltage, high-voltage, Mis-wiring protections they offer - the hardwired units offer protection from thieves! This unit goes inside your coach instead of hanging from the outdoor post. However, buying a 50-amp unit offers no more protection than a 30-amp unit IF your coach or trailer only connects to 30-amps. If your camper only plugs into 30 amp then you should purchase the...

  • Will Hughes Autoformers Voltage Booster and Watch Dog Work on a House with Generator
    The Hughes Autoformers Voltage Booster with Surge Protection part # HU24FR and Power Watchdog Surge Protector with Bluetooth and Emergency Shut Down part # HU77FR are designed for trailers but so long as you don't try to pull more than 30 amp through them it would not be an issue to use them on a home with generator. The booster is basically a step up transformer, that will boost voltage 2% all the time, and if/when your voltage is low 113V or lower, it will go to a 10% boost. The watchdog...

  • Can the External 30A Portable Power Watchdog Surge Protector be Locked
    Hey Harvey! Definitely a valid question - I'd hate to invest in something and run the risk of something happening to it. The Portable Power Watchdog Surge Protector # HU42VR has a loop at the bottom of the door that covers the connection so you can lock your power cord to the protector. An alternative to this is to use the hardwire version of the Power Watchdog Surge Protector # HU77FR which installs on the inside of your trailer as opposed to the outside.

  • Does The Redarc DC to DC Battery Charger Have A Battery Isolator?
    The Redarc DC to DC Battery Charger # 331-BCDC1225D has a built in battery isolator. You will not need to add on an additional smart isolator. You are right it would be overkill, since your trailer is already set up with that functionality.
