You are correct. But it will not connect if there is a problem.
I installed mine on the wall to the water heater and have connectors connecting it in case it goes bad I also can by pass it.

Installed my Progressive remote read out up in the overhead by the electrical readouts. If it does not like the power I'm plug in it will give me an error code. If it is happy it will allow power from the Progessive to the camper. Once established it will show volts, amps, and no error. I've had built in surge protectors for over 20 years and have never had a problem. In my prior Class A twice in one hot summer we were in 2 different campgrounds that had low voltage due to high heat and too many AC's running in campground. Voltage was too low so it would not allow or pass voltage to my unit. I had the option to do the by-pass, as allowed with Progressive's remote, but I chose not to and ran the generator all weekend. Fellow neighboring campers were not happy and campground would not refund my money so I stayed put. Told them, I;m paying for good electric, so either give it to me or refund my money. Thats the nice thing with the Progressive builtin unit, it has a bypass switch so that if you chose to bypass it only then becomes a surge protector like a GFI. On bypass it doesn't protect from high and low voltage conditions.

I just ordered a Progressive Industries EMSHW30C and will install before our summer trip.

I've looked closely at the photos of installations from "Bikerbill" and "PSchw". Best I can tell from your photos it looks like you both installed the EMS after the ATS (Auto Transfer Switch), such that it protects both generator and shore power. If that is correct have you had any issues with this setup?

I noticed that the Progressive installation instructions mention wiring it this was, but their FAQ says not to do it and install before the ATS:

"Should a Hardwired EMS be installed before or after the transfer switch?
A hardwired EMS should be installed prior to the transfer switch. The reason for this is RV generators already have built-in voltage and frequency protection. If the EMS is installed after the transfer switch, this leaves the transfer switch vulnerable to power problems."

I may also contact Progressive and see what they think of the Interstate setup.

I've had no problems with it AFTER the transfer switch as that is what I feel is the best place. Doing so you monitor via their readout volt, amps, cycles, plus error codes but importantly it shows me that when on generator my cycles are not normally 60 but range from 60-62. No big deal but nice to be aware of.

Seems from this string that you installed such that it monitored both incoming A/C and your generator. Progressive reviews suggest a problem with protecting the generator due to a floating gound. Did you have such a problem, and if so how did you resolve it? Can you provide a diagram of how you wired it - Progressive reviews said that wiring intructions were not clear. Thanks much - I am new to the AI and find some things that clearly need improvement but don't want to make it worse.
Thanks

I didn't do anything special and I do not remember any message from Progressive about NOT wiring the generator into it. Call them. They are very helpful. Last week we dry camped for 3 days running the generator each morning and evening for at least 1.5 hours with no problems.

My either. I got it form somebody who sold his AI and had some stuff left over. Knowing of bad power supply in RV parks I sought it would be a good idea to have it. The PO had it rigged to be in between the outside connection which IO found to be a hassle carrying it around and hocking it up every time with the possibility to leave it behind.
So I installed it permanently after the power switch and used quick disconnects so if anything goes wrong I can hock it up as it was before.
Again it works fine used it with different power sources on shore power and with the generator during dry camping.

There is no issue with installing the EMS after the transfer switch and it will certainly monitor the generator power.

I chose to install my Progressive EMS before the transfer switch as recommended by Progressive tech support. I called them to make sure I understood their reasoning as mentioned in their FAQ. The transfer switch has built in electronics that can be damaged. They think it is more important to protect the transfer switch since it is a bigger risk from possible damage from bad power than monitoring the generator that has its own protective circuitry built-in.

Also you can use regular telephone cable to extend the remote display if you use 4-wire telephone cord, also know as data cord, rather than the 2-wire type which looks almost the same. You can tell the type of wire by looking closely at the colored wires in the clear plastic connector ends.
