Surge suppresors vs EMS

There are two types of electric protection devices.

1. Surge suppressors
These devices provide some protection from extremely high voltage (1000+) short duration (micoseconds) spikes. They will not protect you from low voltage (less than 104V) or high voltage (more than 132V).

2. EMS (Electric Management System).
These devices provide the same protection as the surge suppressor does plus protection from low or high voltage. Most also provide a delayed power restoration in the event of a momentary power loss. This helps your air conditioner.

I have seen the term "surge protector" used in a generic sense far too many times. I was curious as to whether people understood the difference between the two devices.

I have had both as well, I installed the Progressive EMS hardwired version in March. So far it's worked great. It hasn't shut me down for any reason but I like that I can monitor the voltage and amps.

I'd like an EMS I can monitor from my phone or the Internet. I'll hold out and use surge suppression until there's a reliable solution that offers this feature. If it's important enough to pay $350+ and up, then it should have the ability to alert and monitor from any location.

ETA: Thinking about it further, I've created my own temperature control device using a networked raspberry Pi and Arduino controller. I could probably do something similar to monitor power from a hard wired EMS. I'll look in to it further and post more info if I come up with a solution.

We just bought a Camco EMS. It was less than $100 more than the surge protector, so it seemed worth the extra cost.

PT50C EMS here. I will NEVER hook up to shore power ANYWHERE without it. What do I do if it ever needs warranty service? I will hook up my spare brand new one that is still in the original box. As I said above "I will NEVER hook up to shore power ANYWHERE without it".

We had a direct lightning strike in the park again late yesterday with several rigs damaged. This is the second time in the past month. Can I say my EMS saved me? No I can't, but I certainly feel safer with it inline.

I think part of the confusion is units such as "Surge Guard", even though they are power management are still are sold as surge protectors, so many newbies think they all operate the same.

I have always had the TRC unit.

So Grumpy, you are saying that my TRC 44270 is a true EMS? I don't see that is monitors for low/high voltage. Nor does it have a timeout delay. It does monitor for improperly wired pedestals though.

A TRC 44270 is NOT an EMS. It is only a surge suppressor. It can, however, detect mis-wiring.

The confusion here is "Surge Guard" is the manufacturers name.
