Surge protectors?

My Class A has a internal surge protector. Does anyone also connect an external surge protector to shore power?

Always... It has saved me already . Slot of the older RV parks have old wiring and we had a surge once. The surge protector did its job. Better safe than sorry

If you have a built in protector, having another one isn't needed

I have both and I always hook up the portable one to check the power if nothing else. Since it is already hooked up, I just leave it. It is easier to replace than the installed one if something goes wrong. I would buy one just to check power before hookup if I didn't have one.

You need one that not only protects against surge, but also for over & under voltage. Most of all, the right voltage!!! Several people have plugged into a 240 volt, 30 amp power source. That is not a good thing at all to do!! Motor home appliances will be fried instantly. So invest in a good one like Progressive Industries. They carry a lifetime warranty. Expensive? Yes, but worth every penny. The hard wired ones will indicate line voltage and amperage, as well as the hertz. They also protect against 240 accidental voltage. Just my opinion.

Not quite accurate. If you have a built it Progressive (or other third-party surge protectors) that might have been installed by a previous owner, you're probably good to go. However, if you rely on the built-in surge protector installed by the manufacturer of the MH, you need to know that they are only good for spikes in power, and do NOT handle low power situations which can do just as much harm to your coach.

With shore power being iffy at many older RV parks, installing or carrying one of the Progressive surge protectors is cheap insurance.

If you have an internal surge protector that is all it will do. Protect you from surges. What they usually won't do is protect you from mis-wired pedestals, or protect from low power, which happens frequently. When you consider all he electronics that are vulnerable. The cost of an outside surge protector, which will cover most faults, is cheap.

If you want the whole story go to WWW.progressiveindusties.net

Good luck.

Surge Protector

All the advice is greatly appreciated.

The one installed in the RV is a TRC surge guard. It states it checks low voltage, reverse polarity, bad ground etc. If I also use an external protector, will that affect the current coming into the coach in any way? Thanks.

A picture or model number might help. They appear to make something similar to what Progressive offers, but yours might not be an equivalent product.

No unless there is a surge, bad ground, neutral etc... Then it will stop it from damaging your coach or even the installed surge protector. On edit, you should understand that if there is a bad surge, it will destroy the surge protector in most cases. Thats a good thing.

I just added a Progressive EMS-HW30C to my old Flair 22D. I think it's a more elegant solution than having to plug in a separate EMS (that might walk off) at the pedestal.

I do run computers, tv, bluray, tv, a bunch of different battery chargers for various cameras and electronics, phones/ipad. I treat it just like the S&B and run them all through separate surge protectors. That's enough peace of mind though.
