As I have scoured forums, blogs and RV sites, I've read a lot about getting power to the RV. There are some great articles out there about 12V and 110V systems and how to maintain everything from your batteries to the wiring. I'll list some links at the bottom of this post.
A lot of people have reported that they can't rely on campgrounds to provide "clean" power. My electrical knowledge is slightly above novice (I can install light switches), so I don't even pretend to understand all of nuances. All I know is that sometimes the campground power is either not enough, it's too much, it's improperly grounded, or it isn't wired correctly.
If you plug your RV into a campground's power outlet and the outlet has one of the above problems, that nasty stuff can travel right into your coach and literally destroy appliances, lights, and electrical equipment.
Surge suppressors are devices that fit inline between the campground's power grid and your coach. Portable ones plug into the campground outlet and then you plug your RV power cable into the suppressor. Built-in suppressors are inside of your coach's power bay, between the interior end of your RV power cable and everything else in the rig. The better surge suppressors not only shut down the power if there's something wrong with it, they will tell you what's wrong with the campground power or power outlet.
My research, as you would expect, came up with several types of suppressors that are good to use with RVs. But one manufacturer's name kept coming up whenever recommendations were made: Progressive Industries.
The coach we are buying will require 50-amp service to power everything in our RV - including the three air conditioners. A lot of coaches only need 30-amp service. When you get a surge suppressor, you need to get one that matches your rig's highest capable requirement. So I needed a 50-amp surge suppressor.
The one I'm planning to get is the Progressive Industries EMS-HW50C. It's a 50-amp built-in energy management system that sells for a little more than $400. I like that it has a lifetime warranty and also has a lot of features.
I'm hoping that there will be some time between when the coach has completed manufacturing and when we pick it up so that we can have the factory service center install it for us before we arrive. If we can do this, it's one of several things we'll buy when they start construction and we'll ship it to factory service for the installation.
