Question:

Would the Hughes watchdog 50 amp be something I could use coming from a generator or is it only good for 120V?

Thanks for your question, Zach.

The short answer is yes, the Power Watchdog # HU74ZR can work with a generator, BUT it depends on the type of generator you have.

Some generators have a “floating neutral,” which can make surge protectors think there’s a wiring problem. If that’s the case, you may just need a simple neutral bonding plug for it to work correctly.

If you can tell me the brand and model of your generator, I can dig deeper into this for you.

@ZachK Thanks for getting back to me, Zach. I was able to find the instructions for your generator and it does list it as a bonded neutral so you wont need anything in addition for the it to work with the Hughes Watchdog part # HU74ZR. Both the power center and you generator will have step by step instructions when hooking up that you will want to follow. Hope this helps answer your question. If you run into any more questions, let me know!
