  • House surge protector
Style: Protector
With this product I did not have to buy individual protectors for all my electronics goods. Is a wise investment
Reviewed in the United States on May 7, 2023 by Rod

  • Now I rest comfortably...
Style: Protector
...knowing that my house is protected from power surges. I did some research before buying the Leviton protector. It is more expensive than some others, but it has the highest specification I found for any protector for single phase residential use. For a long time I have had plugin UPSs or protected power strips for sensitive electronics, but now I live in a place prone to power irregularities. My local power utility will install a whole house protector for a cost of $10 per month added to the electric bill. At that rate the Leviton protector will pay for itself in about 18 months. I am happy to have installed this unit to protect the rest of my electrical devices and appliances from surges. I especially like the indicator lights that show that the suppressor is in good working order. It was a breeze to install; it took me less than 30 minutes from power cut to power restore, and that includes time for opening the panel knockouts and mounting the Leviton protector to the wall. If you are comfortable working around electricity you can quite easily do this yourself. You can find detailed installation instructions on the Leviton website if you need to assess the complexity of installing before buying. Just note that this protector does not come with the four wires required to connect it to the main panel. It needs two black wires (one for each of the two hot electric busses), one white one (for the neutral connection) and one green (for the ground connection). You can use any cable or wires with a minimum of 12 gauge if connected to a 20 amp breaker. I used an offset nipple between the panel and the protector, and this worked very well for my situation as my electrical panel is surface mounted, not recessed. ... show more

  • Leviton 51120-1 Great Product
Style: Protector
I have had my Leviton 51120-1 Whole House Surge Protector for over 5 years, and it still works great. I have had no problems with it. Since having an electrician install my Leviton 51120-1 surge protector, I have not had any of my PC's Power Supplies damaged from voltage surges. Both green LED indicators on my Leviton 51120-1 show my system is working fine. I am very happy with my Leviton, 51120-1 and if it ever needs replacing, I'll definitely buy another one. Thanks! ... show more

  • Easy to Install and Cheap Insurance for Your Home Electronics
Style: Protector
Very easy to install and wire, if you have some experience in home wiring and electrical. Instructions are clear and concise. I had a furnace guy try to sell me a surge protector for the furnace and air conditioner for $400. I installed this myself for less than $200 and it covers the entire house. This is one of those "insurance" things. If it works as it should you will never know. You don't have to be an electrician to install this but if you are electrically challenged be safe and hire an electrician. It should take them less than an hour to install. ... show more

  • Did not work as advertised - But Leviton Honored Warranty Claim!
Style: Protector
Unit was professionally installed in 2011. We had a power surge last week (not lightning) that fried the unit as well as anything in my house that was not connected to a standalone surge protector. Maybe i got a bad unit, there is no way to tell. I will be sending it back to Leviton for testing in hopes they honor their $25,000 protected equipment warranty. Even if you have a whole home surge protector, I would urge you to use standalone surge protector power strips for everything that plugs into an outlet. Learn from my experience. It is much easier to go to the store to buy a bunch of new surge protector power strips than to repair or replace your appliances and electronics. Update - October 12, 2013 I went through the warranty claim process with Leviton and finally received my settlement check today. It was an elongated process and in the end I received payment for little more than 1/2 my total claim. Their warranty excludes any outdoor equipment, so that reduced my claim instantly. They have an (in my opinion) arbitrary method of depreciating damaged equipment which further reduced the claim. Finally, they excluded a few items (which in my opinion were not specifically excluded from their warranty), but it was not worth arguing/delaying any further over a couple hundred dollars. In the end, the process was as you would expect - slow. The warranty is written to Leviton's benefit such that it minimizes their exposure. I must say that I had very low expectations and was happy that they honored the claim. They also provided a replacement Whole Home Surge Protector under the warranty claim. Overall, I am satisfied that they honored the claim. Do I wish i received 100% payment for my loss, of course! However, they could have easily tested the unit and denied any malfunction of the unit and paid me nothing. So in the end, I would have to say that I do recommend this unit and that is why i am changing my rating to 2 stars. I still stand by original recommendation, that even with this unit attached to your main service, you still need surge protectors for every single thing you plug into an outlet! ... show more
