I am another member of the Progressive Industries fan club. Their EMS-LCHW50 unit has protected our RV from low voltage on numerous occasions, a reverse polarity hookup, and another one that had an open ground.

It is even more important if your RV uses a 50 amp hookup. If the neutral wire is disconnected at the campsite, instead of 2 x 120 volts, you now have a single 240 volt circuit. That was probably what caused the pop sound at the state park mentioned earlier.

I would not hookup at a campsite without a Progressive EMS.

Definitely recommend the Progressive Industries unit. You actually need more than just a surge protector, you want something that checks the power source for low and high voltage, reversed polarity, etc. Cost is about $300, but pays for itself the first time you connect somewhere that the power is screwed up. Second trip out with ours I encountered an outlet that was wired backwards (hot on the ground).

Cyn Cyn.....I've been in the AC/heating/appliance business for 40 years so I can speak from experience. Get a surge protector! I won't list all the reasons, but there is great wisdom in having it.

Absolutely Progressive Industries. Saves my circuit boards at a CoE camp ground. Just bought a 50 amp for my 5er. Will sell my 30 amp hard wire for $175 frt included. In box complete like new.

If you are considering generators you need to know the Yamaha 2000s are not compatible with the PI EMS but the Honda's are. If you have the Yamaha 2000 generator you simply do not use the EMS while on gen power, and for the built-in EMS you would just need to add a by-pass switch. I would've gone with the Honda's had I initially known this.

Smile Surge Protector

I have used a Progressive since shortly after I bought my rig. I was it hooked up to power at my home and was hit by a surge that took out one TV and severely jolted everything else. I have had no problems since I installed the protector. The protector did fail once (my fault) and Progressive sent me a replacement circuit board, no questions asked other than the failure symptom.

One caveat, when running on a generator you have to switch the protector to bypass mode. You still have surge protection but the open ground/neutral detector it turned off because generators are not grounded.

Buy a protector and enjoy your rig.

Wow , I have been RVing 30 some years and never had the need for one . Do you have one on your house ? Is your RV cluttered up with sensitive equipment ?
