• How Do You Hardwire Hughes Watchdog Surge Protector 30A In RV?
  Greg, the Power Watchdog Surge Protector # HU72VR gets wired as the first stop on your shore power cord, right where it enters the coach. That way it protects the transfer switch if you have one, your breaker panel, and all appliances. With a transfer switch: Pedestal > Cord > # HU72VR > Transfer Switch > Distribution Panel Without one: Pedestal > Cord > # HU72VR > Distribution Panel You’ll cut your main cord, land the pedestal side on the # HU72VR input lugs (bottom of surge protector),...

• Which Surge Protector Is Best Option For 2023 Grand Design Reflection With 50A Service Plug In
  Kendra, congrats on the new Reflection! Those are super nice. Since your RV has 50 amp service, you’ll want the Watchdog Power Center Surge Protector # HU74ZR. The Watchdog Surge Protector # HU72VR is 30 amp and won’t cover both legs of your panel, and it gets hardwired in which isn't for everyone! The # HU74ZR simply plugs in without any hardwiring, will protect against surges, monitor each leg individually, and boost low voltage on heavy draw days. Have you run into low power at campgrounds...

• Which Surge Protector Is Good For 2005 Newmar Mountain Aire Travel Trailer Stored In Barn With 30A
  Sandy, the # HU84ZR is actually built as a portable-style power center, so it’s meant to plug into the pedestal (or wall outlet) and then accept your RV’s shore cord on the other side. That means it usually lives outside at the hookup point, and its housing is weather-resistant for that purpose. If you’re using it in a barn or garage, that’s fine too - just keep it off the ground where it won’t sit in puddles or dust. Unlike the hardwired # HU72VR, there’s no rewiring involved; just plug...

• Can Watchdog Power Center Surge Protector Be Mounted In Compartment On Its Back?
  Steve, you’re right to ask. The Watchdog Power Center Surge Protector for RVs and campers # HU74ZR should never be mounted on its back. It’s designed to rest on its legs in the upright position so the ventilation slots can do their job. If it’s laid flat, airflow is blocked and there’s a real chance of overheating - the unit will even shut itself down if internal temps climb past 165°. Also, this unit is meant to sit outside near the power pedestal, then your rv plug runs outside to connect...

• Will Watchdog Surge Protector Give Errors When Using Generator With Jayco Jay Flight?
  Alan, that’s a great question. Yes, the Watchdog Surge Protector # HU72VR works fine with generators, but you may see open neutral or open ground codes if your generator has a “floating neutral.” That’s not the Watchdog malfunctioning - it’s protecting your rig. The fix is the Hughes Ground Neutral Bonded Plug # HU33FR. Just plug that into an unused outlet on the generator, and it bonds the neutral and ground properly. (you may not need this, but figured I'd mention it) Do you plan to...

• Can Watchdog Surge Protector 30A Be Used With 15A Residential Adapter For Storage?
  Yes Keith, the Watchdog Surge Protector # HU72VR will still protect your RV even if you’re plugged into a 15A residential circuit with an adapter like Mighty Cord RV Power Cord Adapter - 30 Amp Twist Lock Female to 15 Amp Male # A10-1530DBK. It doesn’t care about the amp rating - it just watches the voltage and wiring for safety. The only difference is you’ll be limited on what you can run in the RV running off only 15A as opposed to 30A. Perfect for keeping batteries charged and the fridge...

• How To Install Hardwired Surge Protector In Winnebago Minnie Travel Trailer With Transfer Switch 30A
  Jim, you’re on the right track. The Watchdog Surge Protector 30A # HU72VR is designed to be wired in ahead of your transfer switch, so it sees the pedestal power before your coach’s electronics do. That way, the transfer switch itself is protected along with your appliances. The install is pretty straightforward: disconnect shore power and turn off breakers in RV, cut your main line, and land the input/output leads on the labeled lugs. We recommend mounting near the power cord entry in...

• Does Watchdog Surge Protector Keep Record Of Faults And Store Them?
  Yes, Mark, it does. The # HU72VR logs each fault in the app, so you can check when, why, and how long power was cut. That’s especially handy if you leave pets or food in the rig and want to know if things warmed up while you were gone on a hot day. Would you like me to walk you through setting up the app notifications so you’ll get alerts on your phone?

• Does Wired-In Watchdog Surge Protector Allow Live Power Usage On Phone App?
  Brenda, the # HU72VR has the same smart monitoring as the boosters. Through the app you can see volts, amps, watts, and even kWh used since hookup. It’s really handy for load balancing - turn on the microwave and you’ll see the amperage spike in real time. Do you want me to walk you through setting alerts in the app?

• Can I Use 2 Surge Protectors On RV 30A At One Time For Extra Protection?
  Rick, you won’t need to double up. Both the 30A # HU72VR and the 30A # HU84ZR already have full surge protection, emergency shutoff, and monitoring built in. Running them in series could actually create more hassle and even issues perhaps. If you mainly want voltage boosting (to keep A/Cs happy in hot campgrounds), then the # HU84ZR is the better fit. If you just want hardwired, permanent surge protection and monitoring, the # HU72VR is perfect. But you don’t need to run both at once -...
