Makes connections so easy to check at the post. Then switch power on unit at the panel.
Could you have used a 30 to 50 adapter along with your 50 amp protector instead of buying a 30 amp unit? I have an adapter that plugs into the 30 amp pole outlet that I plug the 50 amp protector into and plug my 50 amp camper cord into the protector.

I'm the farthest from being an electrician as you can get so I don't understand this, I installed the Progressive Industries EMS-HW50C at my storage unit a few weeks ago and fired up my portable generator to play with it, seemed to work just fine.

It really depends on each generator and how they are wired.

Great job on the install.

I am just plugged in in my drive way - I bought one because we seem to have a lot of power surges in my area and after having to replace a refrig. in the house because of a power surge I just felt it was a good idea.. so far I guess it has saved me more than a few times

To all your surge protector gurus out there... I ordered at EMS-HW50C that should be in tomorrow but as I was reading up on my factory installed Progressive Dynamics 9280 Series INTELI-POWER converter it would seem it does all the same things. This EMS might be redundant and not needed if I am reading everything correctly.
Here is the info on what I have from the factory:
PD9200 Series RV Power Converters

Thoughts?

VERY different devices.

What you now have is a POWER CONVERTER. It takes 120 VAC power and converts it to 12 VDC to charge your batteries and possibly supply 12 VDC to the RV systems.

The HW-50C is a 120 VAC EMS system that will monitor the incoming quality of the shore power making sure that it meets the posted standards for good power. It monitors both HIGH and LOW voltage, monitors the 60 HERTZ cycles, monitors your NEUTRAL and GROUND connections making sure they are correct PLUS it covers you with 3580 JOULES of SURGE suppression during power voltage SPIKES. If any of those conditions were to be out of limits, the EMS cuts all power to your RV in nanoseconds protecting all of your electronic devices in your RV including your Power Converter.

It looks to me lie it would only protect the converter itself, and the 12v side, but not things like AC's, TV's, microwave, etc..

I could be wrong though

Cheap protection when you think about the cost of the 5'er electronics.

Makes sense now that you point that out. Thanks

For instance, my rig is 50 Amps. My surge Guard in wired in, not a portable one, regardless it still protects me when I'm at a 30 Amp site. There in no need to have a second 30 Amp Surge protector, if thats what I'm understanding from your post.
But I never did carry proper adapter at the time due to just having the 30 amp cord and extension.

Sounds to me like it protects only its self.

My understanding from having wired one in, because it is fed by the 120AC circuit beakers, it protects itself and 12V things attached but only to a certain extent and does nothing for 120 AC. I went with a Progressive Industries EMS.

I have a question regarding my surge protector remote install:
I was going to have Camping World install my EMS-HW50C on the $29 install special this month but now I am thinking about at least installing the remote myself for quality control reasons and wanted a little advice.
I would like to install the remote where the control panel is for all the other goodies (levels check, slide control, water pump) in the hall wall. Does anyone have advice to run a wire inside that wall? I would need to run the wire from there to the electric area where the EMS will be mounted which is on the same side of the coach.
