Eaton Surge Protection Device, 1 Phase, 120/240V, 2 Poles, 2 Wires CHSPT2ULTRA - 1 Each

Excellent instructions and ease of installation. My whole house is now protected. Fyi, this model requires a 50 amp double breaker.

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 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.

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 bought the Eaton CHSPT2ULTRA after a nasty power spike burned out my Bose home theater console, and I decided I was not going to risk losing more expensive electronics in the house. This is not a plug-in power strip — this is a whole-house surge protector that mounts directly at the electrical panel and protects everything downstream: TVs, gaming systems, appliances, computers, networking gear, and audio equipment. Eaton rates this model at 108kA surge capacity, which is one of the highest residential protection ratings available, and it is UL 1449 listed for panel-mounted Type 2 surge suppression. The unit itself feels very solid and professionally built. The housing is compact but heavy-duty, and the status LEDs make it easy to confirm the protection is active. This is clearly not a cheap disposable surge device. What sold me is that this model keeps coming up as one of the most recommended whole-home surge protectors among electricians and homeowners because of its high clamping capability and universal panel compatibility. Even recent electrician discussions still point to the CHSPT2ULTRA as a go-to choice when someone wants serious residential surge protection. Installation does require a dedicated 2-pole breaker and is best mounted close to the main breaker for maximum effectiveness, so I would recommend having an electrician install it unless you are comfortable working inside a live panel. Since installing it, I have a lot more peace of mind during storms and random utility spikes. Obviously no surge protector can undo previous damage, but after losing one expensive Bose system, this felt like cheap insurance compared to replacing thousands of dollars in electronics again. Pros: -Excellent whole-house protection for expensive electronics -Very high 108kA surge rating -Trusted Eaton electrical brand -LED indicators show active protection status -Works with most residential panels -Great peace of mind after surge damage Cons: -Requires panel installation and separate breaker -More expensive than basic surge strips -Professional install recommended for most homeowners Overall: If you have already lost electronics from a power surge, this is one of the smartest preventative upgrades you can make. Strong build, highly rated protection, and far better coverage than relying on outlet power strips alone.

Unfortunately, I live in an area where we lose power somewhat often. More times than not it’s a momentary loss of power and this can happen several times within a minute or two. These surges has affected a number of devices in the house that need to be reset or in a couple of cases replaced due to the power surge . A week after I installed both surge protectors, one for each panel, we had one of those situations and the search protectors worked flawlessly. What a great investment. Extremely satisfied with the product. Highly recommend.

Why so difficult? The leads are quite short. I planned to mount the unit through a punchout in the bottom of the panel. I quickly realized the leads would not reach without extending them. However, there was plenty of room inside the panel. I mounted it at the top beside the main breaker. Even at that, it was s stretch for the white wire to reach the Neutral bar. I also had to move a neutral wire down one screw to make the top connection available. Drilling the holes for the screws through the main panel was not easy. The panel is made of a very hard steel. To be sure the screws secured tightly, I drilled smaller holes and kept enlarging them until I got just the right size. I had also planned in piggybacking to the range breaker. Once I pulled the breaker, I discovered very heavy gauge wire connected and sealed with dielectric grease. Rather than mess with that I ran to Ace and bought a 50 amp breaker, which would be to code anyway. Then as I was reassembling the panel, I realized there would be no way to monitor the LED's without removing the panel cover. I had to carefully measure and drill two holes in the cover that lined up with the LED's. The old measure twice thing did not come into play here because the cover shifts position once installed. I ended up drilling FOUR holes and covering two with duct tape. Not electrical tape? No, because the electrical tape is black, and does not match the panel. Well, that and, I'm a guy. Guys use duct tape. It's a guy thing, you wouldn't understand. So that's a total of eight holes drilled through hardened steel, and a few of those were drilled three times to get the right size without stripping. Wiring the unit was very quick and easy and had the leads been long enough, mounting would have been just as easy. It was mounting the unit that was so time and labor intensive. Now that it's done though, I am very pleased with the installation, as is my wife because nothing is visible from the outside when the panel door is closed. As for the function of the device, I have seen the internal components. The MOV's are extremely beefy! I can't imagine typical surges or spikes ever damaging this thing. I would expect it to work forever unless we get hit by lightning. And that's the biggest reason for it. Should that happen, we'll have more to worry about. But I imagine between this unit and plug-in surge suppressors inside, our electronics should survive. Let's not test that theory, but this device is insurance. Also, normal daily surges and spikes do not necessarily damage equipment but their effect is cumulative. Eventually, the electronics will fail. This device, in combination with the normal surge suppressors, should extend the life of my equipment. This is definitely something NO home should be without! Why are these not required by code?

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.

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'm an electrician, I bought this CHSPT2ULTRA surge protector a little over a year ago. Installation was very simple. It's recommended that you use a 2 pole 50A breaker to connect inside your panel, so make sure you have space available. The wires are intentionally short, as it is important for it's effectiveness in the event of a surge. It needs to be as close to the man lines as possible. If you have to extend the wires, then do it, but ideally, they need to be as short as possible. We had a tree come down on a teired hydro line in the area, and the higher voltage lines touched the lower voltage lines blowing up a lot of TV's and equipment on the street. My house had no issues. It's hard to say that this little piece of protection is working because all you see is a couple green LED lights on it, but I'm pretty glad I installed it when I did.

Received promptly and complete. I'd done my research, so knew what to expect and wasn't disappointed. Installation was quick and easy. Now we have some satisfaction that our sensitive home appliances and electronics are protected from nasty surges! I've layered them with both protection at the panel (type 2) and at the plug (type 3) - its the most I can do. Fingers Crossed!

Installation was easy, the specs are good. I have to just assume it's going to do the job if it ever gets put to the test.
