One of the most common questions we get from RVers is about which surge protector is best for their RV. The short answer is that you don’t actually want a surge protector. You want an EMS: electrical monitoring system. The longer answer, however, is important for you to read and know so that you protect your RV from damage in the long run.
A surge protector can help prevent damage to your RV from things like power outages, lightning, and even discrepancies between amperage that works for your RV and what is at your RV park (this is common at older RV parks).
What is an EMS?
An EMS works by blocking any bad electricity from flowing into your RV and allowing good electricity in. EMS devices work to protect you from anything that is electrically flawed and at risk of shorting. This could fry your entire electrical system or even cause a fire. EMS systems truly work to protect the entire RV.
What type of EMS should I buy?
EMSs are available in varying amperage levels. The two are typically 30amp or 50amp. You match the amperage to your RV. There are converters available to help accommodate your needs.
Should I buy a portable EMS or hard wired system?
There are several things to consider when choosing whether you want a portable EMS or a hard wired system. First and foremost, consider whether you plan to stay in your RV for a long time. If you do, then perhaps hardwiring the system makes more sense. If, however, you’re looking at selling and upgrading in a year or two, then a portable device might be a better option.
Portable EMS devices are easy to install, easy to by pass, and can be tested at a campsite more easily. A hard wired system, however, is less susceptible to theft, impossible to forget, and is conveniently located indoors. Ultimately it depends on your preferences.
