Review: Peace of mind - Super easy to install. Peace of mind know the electronics are protected. Cheap insurance. Drill 2 1/4” holes on the panel cover directly over the 2 leds so i can see it without having to completely remove the panel. No room to mount it outside of panel.
Review: Need arc suppression - I like having this installed on my electrical panel and I did it myself. Most people should not be installing these if you do not have electrical experience. I have 30 years of electrical experience so installing it was very simple. If there is anything negative about this it would be that the leads are too short. They should be long enough to reach anywhere in the electrical panel regardless of where on the panel you install it. If you do a lot of research on this first, you will find that the manufacturer requires a 50 amp breaker be used to supply power to the device. In this case you must be careful because of the brand of breaker you have. Some manufacturers do not make their breakers so it will fit this lighter gauge wire. The clamps will not tighten down, so because I happen to have one of those brands, I had to buy a 30 amp breaker so it will tighten down on the wires. I understand the reasoning why the manufacturers of some panels and breakers do this but the clamps or screw terminals should tighten all the way down. That is my opinion. After doing research I also came across That many people say you should not extend the Wires in order to make them reach the breaker or in order to make them fit the terminals on your breaker. I abided by this notion but then realized maybe I did not need to. I am a home inspector and I noticed in other homes that already have this installed by an electrician, that the electricians extend the wires by adding extra length using wire nuts. I do not know if this voids the warranty or not but in my opinion it should not, even though it may. I mean if you have an electrician install it with a jumper wire because it will not tighten down with the brand of breaker that you have then how can a manufacturer expect you to change out your panel and breakers just because they used a small gauge wire. If they are going to recommend that you use a 50 amp breaker, double pole, they should make the device with a heavier gauge wire. One other thing that I heard which could be a real downer. If you research this online you will read that desertcart is not an authorized retailer for Eaton, meaning eaten may not honor their warranty. I cannot say this is absolutely true because I did not contact eaten and you know not everything online is the truth. I have had this happen to me before with other brands and other types of equipment where I search online for a good deal and then I find out that I bought it from a retailer who the manufacturer does not honor. That happened to me with a Frigidaire dehumidifier I bought for my basement and now may happen with this device. I am not going to worry about that too much because if it does fail I will just replace it myself and not pay an electrician several hundred dollars to do it for me. Eaton is a very good brand-name and these are very good devices so I have no regrets buying it on desertcart but I think you should know as much as possible before you buy it.

## Questions & Answers

**Q: Why only one view of the product?   I dont see the pigtail wires.  Does it have wires or does it snap into place like a breaker?   ???**
A: I does have 4 pigtail wires.  It does not snap in.  2 pigtails tie to the breaker you choose, one wire to the neutral and one to the ground bar.  It is mounted in one of the knockouts on the main breaker panel.  If this is installed on an existing breaker panel, you might have to cut an opening in the wall.  I recommend paying the few extra bucks for the cover plate.  It is a really good looking install.  I mounted mine on one of the bottom left side knockouts.  Just Google Eaton surge protector installed to see some pics.

**Q: Can this be located on the inside of the breaker panel, provided there is enough space for it?**
A: Agree with all of the below/above- you are probably going to have to mount outside for the reasons mentioned and it is markedly less effective but STILL indicated and useful. On my other hosue i had a square D panel and 2 open adjacent slots near the 220 entry for the SChneider breaker type surge arrestors0thsi is even better, but rarely an option for most established panels. When these are consumed by a surge you pop another one in -the INTERMATIC external device is interesting as well as it has replaceable sacrificial modules.

**Q: What is the length of the wires that come with the unit?**
A: Just got mine 8-26-21. 
The 4 wire leads on this unit are each a slightly different length, but average around 13".

**Q: how does this work? Why doesn't the surge go through whole panel / other circuits...**
A: When the voltage rises above 300 volts, the MOV in this unit makes a short circuit.   The short circuit has very low resistance -- far less than the resistance of almost any other device in your house.  Electricity takes the path of least resistance.  So the electricity goes (mostly) through this unit, instead of through your other devices.   When the voltage drops below 300 volts, this MOV un-makes the short, and the electricity then flows normally again. 

MOV means Metal Oxide Varister.   "Varister" means Variable Resistor.  It has very high resistance whenever the voltage is low, and very low resistance when the voltage is high.  So, normally, hardly any power goes through this unit.  But when a voltage surge happens, almost all of the power goes through this unit, and almost none of it goes through your computers and TVs.

### ⭐⭐⭐⭐⭐ lots of protection, good performance
*by A***R on January 16, 2022*

I recommend it. This item has a history of good performance. I added it as increased protection over what the electrician installed when we built the house. I told the electrician he did a great job wiring my house (I inspected it as the house was being built), and because I was nice to him, he installed a 5K device in the outside box for free, which provides minimal protection (some, but not enough to make me comfortable). So, I got this Eaton device for extra protection at 108K and put it in the box in the garage. I didn't have room to put it inside the box, so I installed directly to the side of the box (see picture). Super easy to install. As other reviews mention, you need a 50A breaker, so read the product instructions and get exactly what the instructions say to get. And as some other reviews mention, nothing will protect from a direct lightning strike, so don't expect that kind of protection. At 108K (more than 20 times the protection of the 5K device in the outside box), this unit gives me peace of mind. Notice in the picture the two green lights are lit, which means it's functioning properly. I like how I can see it easily whenever I'm in the garage. I drive into the garage and think, "Yep, still protected." I forgot to mention...before you go buy the 50amp breaker, FIRST check your load center (i.e., panel box) to see what type it is, such as, for example, QO or Homeline. If, for example, you buy an HOM 50amp breaker, it won't fit in a QO panel, and vice versa. And, just so you know, the wires are supposed to be short. Some reviewers complain about them being too short such that the unit doesn't fit in their panel. The wires are short for a reason; if you extend the wires beyond their limited length, you risk the device not functioning properly when you need it. So, just because you might not understand the design (e.g., why the wires are so short), don't complain and bash the device as being a poor design.
