Bad ground is instant. High voltage I don't know but speculate it is instant as I agree it should be.

(to me), If the voltage falls below 104 Vac for more than 6 seconds, the EMS will disconnect. A loss of ground will cause an instantaneous disconnect. When an error occurs and then the cause clears, the time delay starts. In your example, if the error occurs every sixty seconds, power would not be restored, because the delay would be resetting to zero each time.

Interesting reply from Progressive, especially since without proof I question it's veracity. ๐ I own a calibrated DVM and used it to calibrate my own EMS-HW30C's voltage readout which as delivered was wildly inaccurate so I am familiar with the inner workings of this device. I also know from personal experience while camping that my unit does trip the instant incoming source voltage falls below it's low voltage trip threshold of 104 vac. Of course the most accurate method to confirm this would be on the workbench, using a calibrated DVM and Variac as a source supply. This I could have easily done back during my career days but now that I'm retired I no longer have access to a Variac and I'm sure not going to buy one just to prove Progressive's claim, one way or the other. My question however is - if their EMS does in fact feature a 6" low voltage nuisance trip delay where is that information in any of their documentation or even online? Common sense says the manufacturer would want to advertise this feature IF indeed it does exist, yet I haven't seen it. :R

Sure - the TRC Surge Guard has traditionally been bagged here on the forums, mostly because of a one year warranty, but new ones now being sold include a limited lifetime warranty as well. Models like the 34830 and 34850 also have a feature the PI units do not - a trip delay of ~ 8" which helps to avoid nuisance trips caused by incoming source voltage that hovers slightly above and below the set trip voltage. I currently am running a hard wire Progressive EMS-HW30C but if I had reason to buy another I'd most likely replace it with a TRC 34830 and install it inside the camper, just as I did years ago with my first Surge Guard, and early version of this same EMS.

Here's yet another classic example of ***Link Removed*** - TRC EMS units now do include a lifetime warranty and conveniently the author neglects to mention the trip feature which PI units do not offer.

I don't think so. They are American made and no other is better. With a lifetime warranty and direct customer support, I'd not stray unless Bestconverter or somebody recommends something else.

So with that logic I suppose one wouldn't bother seeing their doctor about chest pains they've been having, saying they're not dead yet so why bother? Yeah, that's logical. :S

Sometimes our HW50C will take longer to let power through than it does at other times, sometimes up to 10 minutes. We are in no hurry and by the time we get through setting up, it always connects. That's not the way it's supposed to work but also in no hurry to replace it. :B

It works so why waste time and effort replacing it. It's done this for four or five years and still working fine otherwise after over 200 stops in those years.
