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.

  • Recommended Surge Protector For 50 Amp RV
    Hello Rick. You will need to get a new surge protector to use with your new 50 amp RV. You cannot safely use a 30 amp protector, and there is no adapter made for this purpose. Since you are in the market for a new one I recommend the Portable Power Watchdog Surge Protector with Bluetooth and Emergency Shut Down - 50 Amp # HU87FR. This one is Bluetooth/smartphone enables and it has a built in emergency shut off to help protect your appliances. You will find our review video for the Watchdog...

  • Troubleshooting An E6 Error Code On A Hughes Autoformers Watchdog Surge Protector
    An E6 error code on the Portable Power Watchdog Surge Protector # HU87FR would indicate that the Line 2 and neutral have been wired in reverse. This means that the outlet you're plugging into has these two wires flip flopped and the Watchdog is kicking off to protect your camper. The outlet will need to be fixed before you can plug back in and get power to your camper.

  • Troubleshooting Hughes Portable Power Watchdog Surge Protector That Won't Connect to Bluetooth
    It's possible that you might not have the correct version of the application, since my contact over at Hughes says there are 2 different applications and that there is an EPO version of app in app store that would be required to connect to your # HU87FR. You'll want to make sure that on the logo for the application- the dog's face should be black in color with red eyes- this is the EPO specific application. If you can confirm that you've got that application and not one with a different...

  • 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.

  • Difference Between Different 50 Amp Power Watchdog Surge Protectors
    Hey Chrystal! The Power Watchdog Surge Protector # HU47FR lacks the emergency shut down so we can rule that one out. The # HU87FR and # HU62VR both have the emergency shut down so the main difference is how they are monitored. If you're fine with Bluetooth only then you want to get the # HU87FR. This also has a higher energy dissipation at 6,100 joules. If you want to be able to monitor this outside of the range of Bluetooth and you have Wi-Fi available at the trailer then the # HU62VR...

  • Comparing Power Watchdog Surge Protector HU87FR And HU47FR
    Hello Sonia. The Power Watchdog Surge Protector # HU47FR has Bluetooth compatibility. The Portable Power Watchdog Surge Protector # HU87FR has Bluetooth and an emergency shutoff feature which is why it is more expensive. The emergency shutoff cuts power if the current drops below 104V or raises above 132V. This helps protect your electronics in the case of a power surge or drop.

  • Why am I Getting an E6 Code on My Hughes Watchdog all was Good when Campground Tested Pedestal?
    Hello Larry, An E6 code on the 50-amp Hughes Watchdog # HU87FR usually means reverse polarity (hot and neutral swapped or another wiring issue at the pedestal). On 50-amp models it can also show up if L2 has a low-voltage or miswire situation, depending on the revision. Since you tried both 50-amp and 30-amp with an adapter and got the same E6, that points more toward a wiring issue at the pedestal rather than your Watchdog itself. The campground might’ve tested with a simple meter,...

  • Power Watchdog Surge Protector Is Showing E6 Error Code After Several Hours Of Use - What Can I Do?
    One would think that with the E6 error code on the Power Watchdog # HU87FR, the code would pop virtually right away, and not after being hooked up for several hours. Generally the E6 code is a sign that something is wrong with the plug you are using, and not the watchdog unit. It is possible that something is wrong with the watchdog unit itself. The best way to be sure is to plug the unit in to a different power source and see if you get the same E6 error code. If you continue to get the...

  • Can Portable Power Watchdog Surge Protector be Locked to RV Power Pedestal
    In general you just plug the Portable Power Watchdog Surge Protector # HU87FR into the power pedestal of your RV park. If you were worried about theft you could use a cable lock like the Master Lock Python Cable Lock part # 8419DPF to lock it to the pedestal.

  • Stray Voltage or Hot Skin and The Dangers of Miswired or Damaged Ground Wires on Campers
    What you are experiencing is called Hot-Skin and it is extremely dangerous. Hot-Skin occurs when the ground wire on a Camper's shore power feed is interrupted somehow. That allows even normal leakage currents inside of a camper to create a stray voltage on the entire RV, including its “skin,” chassis, wheels, hitch and tow vehicle. So whatever you're touching on the camper is hot and that's what's giving you that tingling feeling. Your leakage must be coming from a low voltage short because...

  • Can Ends of Portable Power Watchdog Surge Protector be Cut Off and Hardwired to Trailer Wiring
    You can cut the wires of the Portable Power Watchdog Surge Protector # PWD50-EPO and splice them together using a terminal block but my contact at Hughes Autoformers mentioned this will void the warranty so you'll want to just connect it per the instructions or return the portable version and get the Hardwired Power Watchdog Surge Protector # HU27FR like you initially planned to do so you remain under your warranty.
