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 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.

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.

Straightforward, no complaints, easy to install. If you know what you're doing, if not, please hire an electrician, it's becoming a necessity Today's homes are packed with many electronics. You need protection.

Installed this on my 23 year old electrical panel because there was no existing surge protection. Disclaimer: DO NOT INSTALL THIS YOURSELF unless you are 100% confident in your electrical knowledge. There are a few things I would mention for fellow DIY electricians: Check to make sure your panel has a 1/2" knockout available on the BOTTOM of the panel. This is because if you only have them on the top or side and your box is located outdoors you're not going to get a water tight seal since there is no O-ring. Make sure EVERYTHING is off before you attempt to wire this in as you're most likely going to have to move some live wires around. Try to place this as close as you can to the 50A 2-Pole circuit breaker as the wires aren't very long and it will work best with the shortest wire leads possible. Also, make sure you buy a 50A breaker that is the same brand as your existing breakers, I had to do some research to find both a compatiable breaker for my load center. It is a violation of electrical code to use another brand breaker than you already have installed. I discovered that EATON bought Culter-Hammer years ago so if you've got an older load center like mine it is OK to use EATON breakers so long as they are the same size/fit for your load center. Mine ended up being the "CH" style. While it is possible to use this with a 30A breaker it will be a waste of money to buy this model as it can only provide the fully rated surge capacity of 108KA with a 50A breaker. I had to move some breakers around to fit another 2-pole breaker on the panel and add a double breaker to remove one to have enough room. Inspect your panel before purchasing to make sure you have room for the required breaker... you are not allowed to double-tap any existing breakers! Overall I would say this is a great product, maybe a bit much for some people who aren't familiar with wiring or electrical codes, but if you are I highly recommend this one to save you hundreds if not thousands toward paying an licensed electrician to put in surge protection.

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.

I installed this in a brand new construction single family home - we had an Eaton panel but that wasn't the only reason I went with the product, it has some good flexibility for the installation and is rated extremely well. Note that this product is NOT Cutler-Hammer - it is EATON - if you are trying to find more info elsewhere, go to the Eaton website and review the information they have there on their surge protection products. Eaton bought cutler-hammer ages ago and all cutler-hammer products are made by them anyway, but if you are looking for info you won't find it under the cutler-hammer name. I knocked out a bottom hole because the panel was mounted with two studs flush on each side of the box. Requires a new two-pole breaker - note that while the smaller ones use a smaller breaker, this box requires a 50 AMP two pole breaker. They are available at your local Lowe's if you have an Eaton box - you don't need an Eaton panel for this product but you need the right breakers for your panel whatever brand and type that is, and it needs to be 50 AMP two-pole (essentially two breakers hooked together). I was installing in my main panel and so on the sides both buses were wired to each other - this is normal for modern service panels and in such case you can wire the ground and neutral into the same side of the panel/same bus. I chose to put it on the side of the box where the utility ground was hooked up. Since I had to come in from the bottom I was able to just put the breaker at the bottom of the box and wire the hots in before seating the breaker in the box. There are some recommendations out there to install these breakers at the top of the panel - there's some validity to this, but if you are installing in an existing panel the benefit you get from moving everything around to do that isn't worth it - and you definitely don't want to do it at the expense of longer wires - the shorter the wires are the better, they are your weak point in the connection. You'll want to cut these down some if you can (though don't go too short - I almost did, whoops!) It is also recommended to have the hots twisted - this is described in the instructions. All in all it was a snap to install - make sure you have the main breaker off while doing this unless you really know what you are doing, and use a voltage tester to make sure things are safe before you get started. Don't forget to consider surge protection for coax or phone lines coming into the house. Eaton sells products for the phone lines I think if you have the traditional ones. For coax like cable TV/internet I recommend the tii 212 device - was a snap to install. You still also need good surge protectors for high end electronics like your entertainment system at the plug - this device won't be able to protect your devices from surges that occur along the same circuit as other devices and there are various other factors within the home. For my computers I use a variety of surge strips/protectors and I have a belkin device for my entertainment system setup. For my wall mounted TV I have a recessed outlet with a leviton surge protector/outlet combo so I don't have to have a strip up there somewhere. Keep in mind that the warranty for this device will only apply if you surge protect other wires coming into you house - such as the coaxial cable line.

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.
