During my PDI I was told my a tech that I should consider purchasing a "Surge Guard ", that the factory on board one has the product name "Surge Guard" but was not adequate for all the electronics the New Aire has on it. Since I keep my coach plugged in nearly 100% of the time this concerns me. The factory on board model is the "Surge Guard/Transfer Switch Model 40350-RVC . Surge Guard being the brand name evidently. I called Newmar and talked to Steve Moser and after he ran it by another tech in the room they came to the same conclusion. I've asked this before but didn't get much response. Any thoughts on this and anyone out there using a power pole (potential theft prone) Surge Protector such as the Progressives in addition to the factory on board supplied unit. They have two models for around $300 - the Progressive Industries 34850 (green) and the EMS-PT50X (black). I don't know the differences in these two or which is the better? Any thoughts there?
Thanks,

I Have the EMS-PT50X and it works great. It's shut down a couple issues for me in the past too so i'd recommend. Disappointing to hear after what you spent on the new aire the on board setup isn't adequate.

First your Surge Guard transfer/Protector only protects against surges which are not the most common problem. The Progressive Industries with EMS (EMS-PT50X) will in addition to surges, also protect against high/low voltage, missing ground or neutral, reversed wiring, frequency, and other faults. And when one of these is detected, disconnect your RV and reconnecting when the fault is corrected.

To clarify my statements even farther mine found a reversed wiring and went and shut it down for me. It definitely saved the day. Guy came over fixed it and we were back in business running the AC!!

We will be installing the EMS (EMS-PT50X) when we pick up our new coach next month. It is the high and low voltage that will get you more often than a power surge will.

Momdoc,
Do you know what the difference is in the PT50X and the been around forever green 34850? Think the PT50X may be latest and greatest and replaced the 34850? I can't find the answer. I sent Progressive an email asking that questions and they, or someone, sent me back a reply asking what the 34850 was? Huh? They may outsource their questions to some to India or somewhere. The 34850 green one has been the dominant surge guard for years. I will let the gang know if I ever get an answer.

You definitely want the PT50X, which is portable and plugs in at the campground power pedestal, or the HW-50C hardwired model. Both give you total protection for your RV!

It's the best investment you will ever make!

The 34850 is manufactured by a different company, Technology Research, under the brand name, Surge Guard, that's why Progressive Industries had no clue as to your question.

From my brief looking, the 34850 does not disconnect the RV from the power source if there are low/high voltages detected, subjecting the RV electronics to damage. It does provide surge protection and does identify issues with the source wiring/power supply.

As others have posted, go with the Progressive unit, or buy from a different manufacturer but get one that disconnects your RV in real time from extreme voltage fluctuations. The main issue many find is that the power post may test fine with any surge protector and once hooked up, will protect from power surges. However, when the CG suffers a voltage drop, for whatever reason, if the device doesn't disconnect the RV, that low voltage will damage the RV electrical devices. Unless you sense a problem and go out and look at the read out of your protector and manually disconnect your RV, the damage is done.

My rig came with a Surgeguard installed at the factory. I already had a Progressive portable unit which I prefer. I use both and the Progressive unit is much more effective.

Recently we were experiencing a low voltage situation when a car hit a power pole outside the park. The Progressive unit cut the power and after I detached it the Surgeguard allowed the power.

Here's a link to different devices which shows what each one can do.

NOT TRUE. There are different types of Surge Guard. Do some research.

The Model 40350 Surge Guard transfer switch looks like it has the same, if not more, protection than the PT50X -- Model 40350.

Just out of curiosity, what did techs (from Newmar?) say the 40350 was lacking?

Whats not true the fact that my progressive shut down a reverse polarity situation and saved the day? No that is absolutely accurate. Maybe you were quoting the wrong response but I can assure that happened.

The warranty alone between the two is enough to go progressive.
