This video is a bit of a departure from our usual. No fancy music or anything. Just all of the behind the scenes removing our Progressive Industries EMS and replacing it with the hard-wired surge guard unit.
This might be super boring for a lot of people, but we hope those that want to know more about the wiring will find it useful.

⚠️ NOTICE / WARNING!!! ⚠️
If you're not comfortable with AC wiring, don't know how to strip the ends of wires, etc., DO NOT INSTALL A HARD WIRED SYSTEM YOURSELF!
Additionally, wiring it yourself might open you the possibility of a nullified warranty. Both the Progressive Industries and Southwire units have verbiage in the documentation stating that it should only be installed by a professional electrician or RV dealer. While this is likely a CYA situation on the part of the manufacturer, it is there in black and white.
❗️Install at your own risk❗️
Wiring an EMS is pretty straight forward. Behind your shore power connection on the RV is a wire bundle. For 50A RVs, this bundle is 4 wires (hot 1, hot 2, neutral, ground). For 30A, it's 3 wires (hot, neutral, ground).
That wire bundle goes somewhere. “Somewhere” is usually a distribution panel or an ATS (Automatic Transfer Switch) for those with an on-board generator.
The goal is to simply put the Surge Guard in-line between the shore power connection and the “somewhere”. If you have lots of slack in the wire, it might be as simple as cutting it where you want the surge guard, stripping both sides and wiring it up.
Most will likely need a bit of extra cable. 6 gauge wire is fairly standard, but match what you already have installed. For us, it was 6 gauge. You can find this at any Home Depot or Lowes and it's commonly referred to as 6/3 Romex. (6 gauge / 3 wires – they don't count the ground – no idea what “Romex” means.)
If you purchased the wired control panel, running this simple phone-style cord to an inside cabinet might be your biggest wiring nightmare! Be prepared for this as well. If you have to run it through some tight spaces, you might have to cut the ends off as I did. This means you need to be familiar with crimping your own RJ-12 connectors.
Get up in your basement, or wherever all of your wiring is, and familiarize yourself with the situation. Make sure you are comfortable getting everywhere you will need to go. You might need to get all the way to your distribution panel if you'll be adding wire between it and the surge guard.
Have a plan BEFORE you get going.
