Question:
We travel with friends. one has a 30A Cougar and I’ve got a 50A Cedar Creek. Is there a version of the Watchdog Power Center that works for both, or do we need different models?
asked by: Brian
Expert Reply:
Brian, you’ll each want the version that matches your RV’s service. The # HU84ZR is built for 30A rigs like your friend’s Cougar, while the # HU74ZR is made for 50A rigs like your Cedar Creek. They both do the same job - voltage boosting, surge protection, and emergency shutoff - but the wiring and capacity are different.
You can use adapters to plug into smaller pedestals and still use the 50A on both, but that would sort of defeat the purpose of getting the bigger unit, and you wouldn't both be able to use it at the same time of course. I'd recommend just getting the correct one for each RV.
Do you and your buddy usually camp together at places with sketchy power?

Hi Andrew, I read you comments you replied back on the question the gentleman had. I am very interested in this product but I just want to make sure I am understanding and clear on what you are saying. My camper is rigged for 50 amp and I use 50 amp when available but we enjoy a couple campgrounds where they only supply 30 amp. So can I still use the 50 amp model and adapt to the 30 amp outlet with the same functions of the 50 amp. Thank you for your response! Joe K
