Eaton CHSPT2ULTRA Ultimate Surge Protection 3rd Edition, 2.38" Length, 5.25" Width 7.5" Height

Straight forward installation. Wires about 14 inches long but wise to install as close to 50 amp breaker as possible to trim wires shorter than 12 inches, per instructions. Encased wires in gray PVC as they entered panel thru the wall. Did not buy expensive 50 amp breaker with status light as the protector already had status lights. This saves significant money. Hire an electrician if you are not comfy working safely with you your service panel!

I don't know what to say except it had a good price. Easy install of you know your way around a breaker box. As for working is wired in and lights are on, I guess I'll see if anything gets blown up.

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.

This is a valuable piece of equipment protecting tens of thousands of dollars worth of electrical equipment in your house. Plus it comes with insurance, guarantees, a UL lab certification, and a lifetime warranty. Don't try to save $50 by getting the cheaper ones. Just get this one and have complete confidence in it. Installation is easy. Put in a 50 amp breaker and hook up two hot wires, a neutral, and ground. That's it. Takes 5-10 minutes.

We had a power outage a few days before installing the surge protector. And a GFI and the kitchen failed. It's important to connect the surge protector as close as possible to where the ground and neutral enter the bus bars. Will need the following materials and tools to install properly if your breaker box is vertical and mounting unit at bottom of box. 50 Amp double pole circuit breaker to match your breaker panel (called for in instructions). One each Red, Black, Green and White 12 AWG stranded wire 2 to 3 feet (60 - 90 cm) long each. May be shorter or longer depending on your panel and mounting location. 4 wire Nuts (Yellow). Electrical tape (optional) Wire strippers. Flat Blade screw driver. Hammer Pliers Small round file to remove burrs. RTV or Silicon Gasket Material. Especially if Breaker box is part of the service entrance and is outside. Ours is outside. It takes longer than you expect to install, if you want to install it right. Depending on your experience 30 minutes to an hour. The instructions call for the double pole 50 amp circuit breaker to be installed close as to the main breaker as possible. In our case we had to move two single pole 20 amp Breakers down which go to Kitchen GFI. And use those positions to install the 50 amp breaker next to the main breaker. Using Pliers broke out two filler tabs for the 20 amp breakers moved down. Instructions also calls for a liquid tight connection to box but there is no gasket included to make a liquid tight connection. If your breaker panel is indoors and there are no water pipes near the panel, you may be able to install it without a liquid tight connection. Or use a silicone RTV gasket sealant to seal the unit tight to the exterior of the panel box. This was the option we chose. And we mounted the unit at the bottom of the box to protect it from the rain and weather. Used a good sized bead so that the RTV squeezed out and into the inside of box completely sealing unit to box. Used hammer and the flat blade screwdriver to knock out the plug at the bottom nearest to the back and pliers to pull it off. Sometimes there is a burr that is left and it will need to be filed smooth. The wires supplied on the unit are about 18 inches long (45 cm) so we had to lengthen the red and black wires to reach to the 50 Amp Breaker at the top near the main breaker. Had to lengthen the green wire to connect them as close as possible to the ground entry/connection point on the ground bus. Had to lengthen the white wire to connect them as close as possible to the neutral entry/connection point on the neutral bus. Although the unit comes with 14 AWG stranded wires up sized to 12 AWG wire to reduce resistance. Do not use automotive grade 14 gauge stranded the insulation is not rated for AC voltage. We striped the wires and used yellow wire nuts that make the connections to the added wire. Then for additional safety wrapped electrical tape in the same direction we turned the nuts. Then fold it over the nut on to the wire and taped over for additional safety. Now house is fully protected against surges. But still will use 120V surge protection strips to provide additional protection for electronic devices. Added this unit to protect the electronic controls on our new dryer and our induction range. But it also provides protection till the refrigerator, microwave and air fry oven which all have electronic control boards and adding a hundred twenty volt surge protector is not easily done. The reason down grades to 4 stars is because the wire length is too short and had to add on to make it work in this application and they did not provide a gasket which are available from McMaster-Carr and are intended for a 1 inch hose washer. Wasn't about to buy 100 pieces for one installation and pay shipping. If you have everything on hand it will take you about 30 minutes to one hour to install it. But because we had to run back to the store to get additional wire it took us 2 hours. The wire is relatively inexpensive at $0.39 a foot here locally. It's better to buy a little more wire and cut off the excess then to have to go to the store again. The 2 pole 50 amp breaker was also less expensive locally and under $10. The reason this unit was installed in the way we did is because I used to work for a commercial contractor and had to learn about and specify on the permit drawings how to properly install surge protection and lightning protection. *** Up Date March 2019*** we have had a couple of thunderstorms here locally in February and March. Saw the surge protector in action. A surge came from the Utility side (this is why you connected closest to the main) and the surge protector acted immediately and shunted the surge to ground. Lights did not dim appreciably but didn't notice our computers and TVs turn off just for a second then turn back on. The surge protector work the way it was supposed to. When it's shunted the surge to ground there was a temporary loss of power, but once the search had passed. The Protector returned back to normal mode... that's why the TV turned back on. And my son's computer did a check to make sure everything was running okay. We also have standby power supplies with surge protection on our computers. That extra effort to install it correctly protected all our electronics and the new washer and dryer we just purchased.

This item was recommended to me by an electrician, just had it installed as I get lots of power surges. It keep my electronics safe.

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 Amazon 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 Amazon but I think you should know as much as possible before you buy it.

Recommended by an electrician that replaced my electric panel at my Mesa, AZ winter home. I installed one at my Mount Vernon, WA (communist) home for hundreds less diy.

Update Aug 2023: Well we had a lightning strike hit a tree 20ft from our house. Caused an attic electrical fire in our neighbour's house, but I'm confident the whole house surge protector saved most of our devices. Other than a few items nearest to the lightning strike, everything else in our house is working. Can't say enough good things about this product. Now to replace it with a fresh one since it's ability to protect us has been diminished (even though it's still working). ---------------- I've been wanting to install a whole house protector for awhile. Looking through all the reviews online, this model comes as the best overall deal, and it's universal since it connects to any 50A breaker. The install is very simple. 2 wires into a dual pole breaker, 1 wire to ground, 1 wire to neutral. The breaker, while others recommend placing as close to the main in line, can go anywhere in the panel. Surges will always look for the shortest way to ground, so it's unlikely you have anything closer than the surge protector. It's more important to keep the wires from the protector as short and kink free as possible. The 2 green LEDs ensure it's easy to check if the protector needs to be replaced. Only time will tell how effective it is, but with the 108kA rating, it gives some peace of mind.

Compre dos protectores los cuales instale en centros de carga separados, me ha funcionado muy bien, realmente lo recomiendo por su propia y sencilla instalación, la calidad precio funcionalidad, sin duda alguna lo recomiendo; en el sector donde vivo, se han presentado problemas en el suministro eléctrico domestico, a un vecino se le dañaron unos equipos mientras que en mi domicilio, no paso nada.

I purchased a new house and the seller had to change some electrical components due to a surge. The home inspector suggested this Eaton surge protector to have as a small purchase which offers a safety net for the whole house. Sure enough my.electrician suggested the same . I went with the best one because it's the night mare of having to deal with blown appliances rather than one protector . All in all it's easy to install , I use a electrician because there was other work to be done as well. But if you have no knowledge of such electrical item then please don't take a chance and get an electrician to do the job Trust me it's a small investment for peace of mind.

Had a surge in my neighbourhood several years ago, that blew the circuit board ,on my garage door opener. Installed the surge suppression unit to protect my household appliances. As well as, surge suppression from local devices, furnace motor etc ,from damaging other devices ie electronic rusting. The device is meant to be a bypass circuit for surgess. Electricity takes all paths. It is a misnomer ,to say electricity takes only ,the shortest path. It is meant to buy time when a lightning strikes for the mechanical breaker to trip.

Mounted it to the top of my panel - had to turn some other clamp screws to make enough space for it. Have to move around some breakers to make space to install the 50amp breakers in the closest location to the surge protector. Since the wire gauge is 14 AWG, I stripped the two red & black wires longer and folded them to make the amount of wire thicker to better hold and make contact under the breaker screw. For the neutral & ground wires, I wanted to connect them as close as possible to the neutral & ground entry points on the panel (which is at the bottom for me). So I used 12 AWG solid cables to make those connections, then used Wago splicing connectors to connect them to the stranded 14 AWG cables from the Eaton. Overall not too difficult of an installation, just need to find the ideal mounting location and have the 50amp breakers close to it.
