Customer Questions & Answers

What do I do after the power has surged?

How do you reset the unit so it again protects after it has experienced a surge?
Asked by: John
Leviton SPD has a light system for this model. If both are green then the SPD is OK. If any lights are red then the device is no longer working and needs to be replaced. You will need to consult a Licensed Electrician for your local area for an inspection of you main panel for damage. Panels are designed to take a certain amount heat from overloads but after they reach their maximum overload melting of this design occurs and needs to be replaced. Leviton has directions for you to follow for warranty of their products and what they protect. You may qualify for warranty replacement of any damages that occurred while being protected by Leviton SPD.

Can the surge protector be wired directly to the lugs where the incoming power is. Line side? In between meter and main 150 amp switch

Asked by: BigG123
No, Power companies most likely will not allow this set up.

If the unit blows, is power restored?

If the unit suffers a big surge & blows, is power to the house off? What is required to restore?
Asked by: James
If the Leviton SPD takes a spike or overload and the lights on the SPD are red then the SPD is no longer providing protection. Power most likely can be restored if the Main Panel has not received any damage from overload. A license electrician will need to look over your Main Panel to determine if any damage has occurred. Leviton warranties their devices if installed correctly and has procedures to follow for replacement of the SPD and damaged equipment. Just follow directions on box or website.

120/240-Volt Residential Whole House Surge Protector is rated 4.6 out of 5 by 29.
Rated 5 out of 5 by from Great Insurance This surge protector is awesome. With computer chips in nearly everything from TV's to refrigerators and even the new stoves this is about the best insurance that money can buy. The installation was easy enough. I had an empty circuit breaker at the bottom of my meter base outside my house. The surge protector is rated a NEMA 4x meaning it is pretty much waterproof so I installed it there. It's actually before my house circuit breaker panel making the location perfect for good protection. Everything went as planned and in this situation no news is definitely good news. With all of the electronics in homes these days and insurance deductibles so high installing this is a no brainer.

Rated 5 out of 5 by from It works! I have the proof I installed one on each of the two 200amp main panel boxes in my house about 5 years ago. Prior to that I had lost a lot of stuff to power surge and lightning strikes over the years. Yes I said strikes. The chimney has been rebuilt and the same sheet of roofing replaced twice. Yes, it does strike the same place twice. This morning the house took at power surge from the power company and whole house surge protector did its job. I know protector took the brunt of it because the face blew off the front of it and it landed 4 feet away. See the picture attached. Off to Depot to get another one today!

Rated 1 out of 5 by from Complete Junk! Had it for 8 months, then had a bad storm with severe lightning, zapped the power... Complete Junk! Had it for 8 months, then had a bad storm with severe lightning, zapped the power pole, which popped the pole fuse and upstream branch pole fuse, and then the surge took out my $1000 alarm system main board and cordless phone station ($1400 in damage). Surge suppressor was NOT affected, and still had green lights! Sending in a claim to Leviton. Go with a $200 80KVA rated unit, Square D brand or better.

Rated 4 out of 5 by from Good primary protection 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.

Rated 5 out of 5 by from Best for the $$ 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 out of 5 by from Great Price! Great Protection! Simply Great Install! Having had numerous power surges damage and destroy expensive electronics like laptops and home appliances over the years, the prospect of having whole-house surge protection was a welcome one to say the least. So when saw this item available in the Home Depot Seeds campaign, I quickly selected it. Initially, I expected to be able to install this product myself since it is intended to wire directly into the top-left and top-right 20A circuit breakers, the reality was that in order to have the manufacturer honor the covered devices warranty, a certified electrician must install this product. Now obviously if you have a friend or family member that is a certified electrician this could cost you nothing more than a favor being called in. For me, I contacted a local company who offered to install the product for a reduced cost due to the easy and quick install. Overall the install went smoothly other than working around some odd-ball wiring from the previous owners of our home and I would estimate it took no more than 20 minutes and the install was very clean. Now it would seem apparent that I can't speak to how well this product will protect against a lightning strike or a surge from the power company since I continue to pray that I never have that happen. Based on the Underwriter Laboratory confirmed specifications of this product though, I am reasonably confident my electronic equipment is protected from such an event. With this product costing a fraction of the amount of many of the other whole-house surge protectors on the market and the easy/clean install, I give this item full marks and I fully recommend this product to all home owners.
