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

Easy install and good protection for whole house.

Before you order, be sure of what type of circuit breaker box you have. Installation should be done only by someone comfortable with handling electrical parts and wiring. Works perfectly.

We had a power outage a few days before installing the surge protector. And a GFI and the kitchen failed. Its 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. Wasnt 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. Its 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 didnt 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 its 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... thats why the TV turned back on. And my sons 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.

Installed easily on the outside of my panel board in my basement. You do need a 2-pole 50 amp breaker in order to install it. Luckily, havent had any kind of surge that has tested the unit. I will update the review if it ever happens.

If you have a basic knowledge of electrical wiring and dont mind working in your electrical panel, this will be a fairly easy job. Its pretty straight forward. I added a 50 amp breaker at the top which is dedicated to the Eaton surge protector. After attaching it to the panel through a knockout, it was just a matter of connecting the red and black wires to the breaker and the ground and neutral to their respective bus bars and it was done! Two green lights. Not sure how this will perform, but at least I have some protection against surges which I didnt have before installing this.

well worth the investment. Think of it as a very cheap insurance policy. We have over $10,000 msrp in appliances and wanted to make sure they were protected.

Not a thing.

Good price ,beats the big box stores

Easy to install, but wire leads could have been a bit longer.

This is a good product that would have garnered 5 stars but for the lack of wire length. The hot wires are not long enough to reach even the first breaker if installed in the top or bottom of a panel. I had to add pigtails to reach the breakers. The neutral and ground are sufficient. A few more inches of wire wont break the bank people and sure would make the installation easier.
