I should also add that in addition to the power cord surge protector, we leave the (supplied with recent model AS) small power monitor (with three visual indicators) plugged into the bathroom electrical receptacle as a night light ... it just provides another eye to what is going on with the electrical system.

Every rig has a different location for the main panel and hooking up a hard wired unit may be easy or a pain. The portable unit makes more sense and that's what I will go to when my hard wire unit fries. Plus you can drag it with you if you trade your rig.

This item boosts voltage by as much as 10% (e.g. from 95 volts) before it gives up, turns off the power to your rig and waits for better conditions before resuming the power feed.

The Progressive solution may be more cost-effective since it protects both against surges and low voltage, but we didn't know about it then.
Thanks for your input. I am looking at getting the Technology Research unit for New Lucy. I have never had a surge protector before. I am reading that this unit is both a surge protector and a voltage regulator. Is this correct?

PT 30C has a decent price today at Camping World on line. $218 plus shipping $9. Ordered. Two weeks shipping which is ok for me but a tad slow by today's standards. Jim

It doesn't regulate, only monitors the voltage, shutting it off if it is too low or high. Nifty unit, goes through a variety of power checks when first plugged in before it allows power to pass to your Airstream. I feel very good about the power source with this plugged in to protect our electrical system.

Yup. Got one. And mrprez, I never go shopping after I have been shopping. Another way to avoid being disappointed. But thank you for the heads up anyway. Jim

Cool Regulators and suppressors

Hi there! To be clear, we own both a surge guard and a voltage regulator. The surge guard is *not* a voltage regulator. While a TRC surge suppressor / Progressive EMS is sufficient to prevent disaster, you may be happiest having both a regulator and a suppressor.

Here's the configuration if you use a regulator and a suppressor. If you have a 50 amp system, replace my 30's with 50's.

Post ==> 30-amp extension cord ==> Voltage regulator ==> TRC Surge Guard *or* Progressive EMS ==> Furion 30-amp cord ==>Trailer

This way, the voltage regulator minimizes the potential variations in voltage coming off the post, boosting voltage by as much as 10% (e.g. guaranteeing clean service on the output side even with input voltages as low as 95 volts). However, the regulator does *not* protect against anything else. So, you still need a TRC surge guard or Progressive EMS in the circuit after a regulator. Either of those will protect against surges, open neutrals, etc. Lastly, you plug the now regulated and surge-guarded output into your trailer.

As a matter of convenience we put the voltage regulator and surge guard under the trailer where they are harder to see and perhaps less likely to be "borrowed". We never just hang the surge guard from the post. It looks way too interesting. (Obfuscation is not the same as security, but at our trailer the average looky-loo sees an extension cord going under the trailer and a Furion cord coming out from between the wheels...probably nothing interesting going on under there, not even worth bending down to take a peek.)

We didn't wire this stuff into the trailer because the purpose of these devices is to sacrifice themselves if necessary. If (when?) they get smoked by an evil power incident, we can replace them without messing with any trailer innards. If the devices are stolen and the baddies stop with carrying off 30 pounds of electrical gizmos they don't really understand, I guess we'll be grateful the incident wasn't worse.

The EMS unit works very well (installed the hard-wired model). What I particularly like about it is that IF there is an issue in the campground, you'll get a code on the display BEFORE it connects your trailer to the power. I had one campground with a polarity issue, and another with inadequate voltage to run my A/C. You always have the option to override it, but I sure wouldn't. It's available in both a 30amp and 50amp model and (surprisingly) is made in the USA!
