Lots of people have “dog-bone” style surge protectors, something that plugs into the end of their RV’s provided cable and then into the park’s power supply. Although they work, they’re not the most elegant solutions, and if you’re staying someplace sketchy, they’re easily stolen. I prefer to have the surge protector inside the RV, and have it be completely automated and impossible to forget or loose.
Surge protectors can also prevent you from hooking up your rig to a power source that isn’t set up correctly. This happens surprisingly often in RV parks, and you’ll be glad your surge protector is doubling as a wiring-inspector too!
Progressive Industries EMS
This is more than just a surge protector, it’s a complete Electrical Management System (EMS). It protects against just about everything your RV can encounter when connecting to shore power.
- Under Voltage
- Over Voltage
- Open Ground
- Open Neutral
- Reverse Polarity
- Accidental 240V Protection
- A/C Frequency
- Miswired pedestal indication
- and of course, surge protection
Progressive Industries EMS-PT30X RV Surge Protector
Similar to the unit above, this device will help protect your rig from fluctuations in shore power quality and bad wiring at the pedestal.
This unit can be easily stolen though, and is an extra piece of hardware that must be attached and detached manually.
I would only recommend this unit if you are looking for a temporary solution or for whatever reason cannot install a permanent EMS like the unit above.
