Mod to Protect the Electronic in my 5th Wheel

This past winter we had a few Power Outages and Power Surges. Because I am hooked to shore power 24/7 When my 5th wheel is parked at home. I decided that I needed to do something to Protect the Electronics and Appliances in my 5th wheel. What follows is a picture story of what modifications that I did.


This is the little Cabinet that I modified in another post. It is located at the rear of the 5th wheel where the power comes in.


When you open the door to the little cabinet this is what you see.Great big holes where the factory cut out the panel to run a couple of wires. Senseless, Stupid is to kind for the stupidity of the manufacture to allow such crap. Exposed Insulation and a Large Gap. While making this Upgrade / Mod I decided to do something about this problem.


I removed the cabinet so I could get in and make some changes. time to cover the large cutout and add some more insulation.


I added insulation and used a 1/2 inch piece of plywood cut to fit the opening and drilled holes for the power cord and romex wiring. The panel you see on the left is to cover the plywood and make a back for the little cabinet.


Much neater and cleaner with no big opening.


The 30 amp EMS system From Progressive industries arrived to day and is ready to be installed. It replaces the junction box in the previous pictures.


The Progressive Industries EMS-HW30C Electrical Management System RV Surge & Electrical Protector is installed where the junction box would be if used.


The EMS is installed with the remote and is ready to be tested. The little remote with digital screen is at the top of the picture. It also has a switch to by pass the EMS when using a ungrounded generator.


The test passed. The remote displays continuously Voltage, Amps, Input and Output, and any error codes. Now to install the little cabinet.


The little cabinet is installed and now all of my appliances and electronics are protected from Power Surges, High Voltage, Low Voltage, No Ground, Reversed Polarity, and many other things that you find when hooked to a RV park or campground Pedestal. I like this fixed mounted one because I can see at a glance what is going on with the power and I never have to worry about it being stolen Like a portable one. The unit can be installed in a compartment or any place where the incoming power is. The remote comes with a 14 ft telephone cable. Everything is very easy to install and requires no special skills.
