Rated 5.0 out of 5.0 by HandymanBill Leviton 51110-SRG Excellent Value Surge Protector
Although I am not a certified electrician, I have wired several new homes in accordance with the NEC code. They were inspected and approved by the electrical inspector. Therefore, I was confident in installing this unit in accordance with the installation instructions. Anyone with some electrical wiring experience, especially in breaker panels should be able to install. Otherwise, hire an electrician.
Be advised that the warranty is not valid unless installed by a professional electrician. I was willing to take this risk.
In this age of appliances with electronic controls and microprocessors, everyone should have a whole house voltage surge protector. The cost is a fraction of a service call to repair a damaged control.
I looked for value - price, performance and ease of installation. This Leviton 51110-SRG has a rating of 3400 Joules (a Joule rating value is how much energy the surge protector can absorb or dissipate before it fails). 3400 is a good level of protection. Also the response time, although not listed is short, but may not be not short enough to protect computers. They are not listed in the warranty. You may need extra protection for computers.
I purchased the surge protector from my local Home Depot.
It was easy to install with the installation instructions provided. First thing was to turn off the main breaker to my 200 amp breaker panel. Then the breaker panel cover was removed. There are options on how to mount the surge protector. I elected to install directly to the breaker panel by punching out a perforated knock-out hole adjacent to where the unit would be attached. The outer plastic flush cover was removed. The connector at the base of the surge protector has four wires (2-black, 1- white and 1-green. They all pass through the knock-out hole and the unit is secured to the panel with a connector nut provided.
The black wires (power) must be attached to two new dedicated 110 v breakers (one wire per breaker- I used 20 amp breakers, the max specified by Leviton). and pushed them into the legs of the breaker panel. The breakers must be positioned side-by-side to protect both legs of the 110/220 V system. Since I installed the surge protector adjacent to the breakers, I was able to cut off a considerable length of the black wires as recommended by Leviton before stripping and attaching. I left the green wire (ground) and white wire (neutral) long enough to reach and be attached to the neutral and grounding bars. The wires come 18 inches in length (the shorter the power wires can be cut,, the better the protection).
The breaker panel cover is then screwed in place and the main breaker turned on. The new dedicated breakers are turned on. At this time the two lights on the surge protector panel will light-up showing you have protection.
The whole job took about 30 minutes.

PLEASE BE SAFE - if you don't have the experience or are not sure, have a professional do it for you. It is not that hard to install - but you must do it safely.
1. Have all the stuff you need on hand (tools, 2 20 amp CB, and the surge protector)
2. Make sure you have two free spaces in your CB panel
3. Turn off power at the incoming power at the meter CB
4. Remove CB cover
4. Attach the surge protector to the CB box
5. Install the two CB (one on each leg) make sure they are installed correctly
6. Black wires go the CB one each - White wire to neutral - Green wire to ground (make sure you have a tight connection)
7. Re-install the CB cover
8. Turn on power at the meter
9. Make sure you have two green lights on the surge protector

Great price. I've had a unit similar to this take a near-direct lightning hit. It destroyed the supressor but did not damage any equipment. This unit has a HONEST warranty. Don't be fooled by the warranty claims. Leviton will cover your equipment up to $5000. Other manufacturers (ie cutler-hammer etc.) offer higher warranties but they only cover costs up and above what your home-owners insurance will cover. CH may never have to pay any claim and your insurance premium will probably go up. If you have a quality product, you should stand behind it, not behind the insurance company.

A couple weeks ago a nearby lightning strike took out two GFI outlets, the electric fence charger and a cordless phone base in the barn. Did some looking and found this product.
I just installed one on a sub panel in the barn and so far everything is great. (4 wire feed to the barn, separate ground and neutral, local grounding electrode in barn connected to grounding conductor from main panel in another structure with its own grounding electrode.) The Neutral to ground protection included in this suppressor in addition to the two line to ground protections is just what this application needed.
It is low cost but it still looks like it is good quality and the specs are as good or better than the more expensive units I see advertized. It is not as sturdy as a package could be (rtv sealing wires is a bit messy though it is hidden after the install), but it is good value.
It did take me a few minutes of head scratching to realize the frame in front is only for flush mounting to a wall and needs to be removed and discarded to mount the suppressor to the side of a panel.
Looks like good quality once installed.
I just placed an order for two more for other locations on the farm.

Rated 5.0 out of 5.0 by Shane great for the money
This whole install only took me about ten minutes (I'm a Journeyman electrician) and for the price its well worth it. I prefer the Eaton brand protector but at the time I could only afford this.... but I'm not knocking on Leviton. I chose to install this at the bottom of my service panel for a quicker installation. The top of the panel has all the Wires from the home coming into it from there. so when cutting out the Sheetrock to recess the unit there is a less likely chance of hitting a live wire. I just took the unit and placed it on the wall and traced it out so the whole is perfect shaped. then I knocked out the proper 1/2 KO in the bottom of the panel. inserted the unit into the wall and fished the wires through the knock out then locked the unit in place with the provided lock nut. Then installed the flush mount plate. once that's done I installed a two pole 20 breaker at the bottom of the panel so the wires can be cut as short as possible. now the two pole breaker will attach to the panel and allow the unit to protect both phases. and don't listen to what anyone says about the breakers need to be installed at the top of the panel as that is not true. Surge goes for the path of least resistance and will find the unit first before any of your appliances or electronics regardless of the breaker placement. anyway I cut the two black wires to size and attached to the two pole dedicated breaker then I cut the green and white wire to length and attached to the neutral bar. all wires must be as short as possible and never spliced to be made longer. shorter the better. but the most important ones of all to be the shortest are the green and white wires as those or the wires that send the surge back out of the unit, onto your neutral/ground bar and then is released back into the earth. So the shorter those leads are the quicker that can be done. this unit also has a decent warranty and specs as well. over all bravo. in my career I have installed 100's of whole home surge protectors and this one is pretty good for the price. that's why I'm giving a 5 star rating. easy install, great price, and good warranty

On a 220 volt system, split to 110 for specific service, this unit has greatly extended the life of my 110 vac appliances. Power surges here are common and were wreaking havoc on my 100 vac appliances....great product.

All was not as expected. The unit does not have the connector to the panel at the same offset as the holes in the panel. I had to use knockouts to move the hole closer to the front on the panel on the circuit panel.. It is now in place.

Rated 4.0 out of 5.0 by Kahless Appears to work well
I haven't had to use it yet, but hopefully I won't. If it works well, I'll let everyone know. It wasn't that easy to install, the directions could be clearer. Also if you don't have an electrician install it, the warranty is void. Not a great way to treat someone with knowledge of electricity.
