Electrical management system

assuming you are talking about a surge surpressor, the answer is YES.
spend the $250-$350 and eliminate potential problems. I'm sure you will get responses such as "Ive RVed for 80 years and didn't have one and have never had a problem. I think one potential problem is that continuously operating appliances with improper voltage can produce an accumulative effect or so I have been told.

Have to agree with Bumpy,an EMS is really good and cheap insurance, if you factor in loosing some of your electronics on your RV.

Progressive Industries is the best on the market,American made and a Lifetime Warranty.

We have the Progressive Industries EMS-PT30C and the few times we do use hookups in campgrounds it is safe insurance, highly recommend using some type of Emergency Management System.

X2 on Progressive Industries. Get the best one they have. It is excellent insurance.
I have the PT-50C

Never had/used one for many, many ears of camping/RVng...........but that was because we normally went to same places in the area we lived and were familiar with the CGs and our RVs didn't have all the 'electronics'

Then we decided to go FT and travel ---that is when we decided to invest in a 'protection device' because we would have no idea/knowledge if the various CGs and because everything in new rig had a circuit board

We have a PT-50 also.

What are some specs a person should look for when selecting a surge protector?

One of the first things anyone should do is to get past the use of terms such as "surge protector" or "surge suppressor". Think "Electrical Management Sysyem" instead. For many of us, the spec to look for in an EMS is the brand name "Progressive" on the box. After that, your choices are narrowed to ampacity, hard wired or plug-in, and with or without remote display. Surge is just one aspect of proper EMS. Undervoltage and brown-outs are more damaging and more frequent than power surges in a campground environment.

I'll make this simple for you and I doubt there's anyone here who would disagree. :)

If your rig is wired with 30 amp main service and you want a portable unit invest in a Progressive Industries EMS-PT30C

If your rig is wired with 50 amp main service and you want a portable unit invest in a Progressive Industries EMS-PT50C

If your rig is wired with 30 amp main service and you want a hard wire unit invest in a Progressive Industries EMS-HW30C

If your rig is wired with 50 amp main service and you want a hard wire unit invest in a Progressive Industries EMS-HW50C

Electrically the portable and hard wire units perform exactly the same, the portable is obviously the easiest to use because you simply plug it into your campsite service and plug you rig's main service cable into it, the hard wire unit must be wired in by someone familiar with electrical wiring. The hard wire units offer some additional advantages such as delay that can be internally switched from 15" to 136", the portable units are fixed at 136". The portable units are sealed and must be returned to the manufacturer for service (if ever needed), the hard wire units are user serviceable.

I personally own an EMS-HW30C but wired it into my rig using 30 amp connectors so I can unplug it anytime, just as I would a portable version. I also added a switch so I can control the delay without having to open the box.

Sound Guy possibly forgot about the EMS-LCHW30 and the EMS-LCHW50. These are also hardwire units, but have the display on the box rather than in a remote unit and seemingly lack the bypass switch that the fancier hardwire ones have (on the remote unit).

No I didn't forget but regard them as a poor choice since the display is on the unit itself and because a hardwire unit is usually placed where it's out-of-sight, out-of-mind the LCH series really doesn't make a lot of sense to me, especially since a remote display can't be added to these units. Some who may be able to locate an LCH in a cabinet might be interested but if the unit is going to be buried under a dinette or sofa or in an outside compartment the LCH wouldn't be my choice at all.
