Answer: 
There's really nothing to do. The device doesn't "trip" like a circuit breaker; it works all the time, but is only active (that is, diverting excess power to ground) when the voltage on the line (hot) buses in the distribution panel goes above a preset limit. Whenever a surge (high voltage) situation occurs, the device does its job; the rest of the time, it simply sits in "standby" mode, waiting for a Read More
There's really nothing to do. The device doesn't "trip" like a circuit breaker; it works all the time, but is only active (that is, diverting excess power to ground) when the voltage on the line (hot) buses in the distribution panel goes above a preset limit. Whenever a surge (high voltage) situation occurs, the device does its job; the rest of the time, it simply sits in "standby" mode, waiting for a surge. If the total current flow through the device gets too high for too long, one or both of the circuit breakers connecting it to the line buses may trip. If that happens, you'll need to reset that breaker. (If the breaker trips repeatedly, contact an electrician.)
Once it's installed, the only real maintenance is to check the device occasionally to be sure that the indicator lights show proper operation. If they aren't showing the proper status, the device will need to be repairs or replaced. Read Less

The unit isn't a circuit breaker; it doesn't "trip" and have to be reset. It simply diverts excess power to ground when the line voltage goes above a preset limit. When the line voltage drops back to a safe level, it remains in operation and will work again automatically when the voltage goes above its activation level.

Answer: 
Once the 51110-SRG takes a large enough surge, the unit will no longer provide surge protection and must be replaced immediately. The LED indicators on the face of the surge protector will alert you when the device is no longer surge protected.

In simple terms, no, the device can't be connected to the lugs where the incoming power lines connect to the disconnect switch. The device needs to be connected to the distribution panel (breaker box) through a pair of 20 Amp breakers, much like if you were adding two new circuits to the panel. This means that it must be on the home (inside) side of the main disconnect switch, rather than on the line Read More

Answer: 
Good day,
The leads from the 51110-SRG must be connected to the power mains through a 20 Amp (maximum) disconnect and fusing means. Either dedicated branch circuit breakers (independent single-pole preferred), or a fused disconnect switch may be used.

This device connects between the line (hot) buses and the neutral and ground buses in the service panel. It detects voltage (not current) on the line buses above a preset limit and shunts the excess to ground. If it's properly connected to the buses through a pair of 20 Amp breakers, the breakers should trip well before the device gets fried. Regardless, however, the device isn't in line (series) with the line buses, it's simply a regulated tap from the line buses to ground. If the device fails completely, it shouldn't shut down power to the house, or have any impact on the circuit breakers (which provide high current protection) for other circuits; it'll just leave you without surge (high voltage) protection, which is exactly the state that homes without this type of device are in all the time.

Rated 4.8 out of 5 by 25 reviewers.
Rated 5.0 out of 5.0 by 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. September 5, 2016
Rated 5.0 out of 5.0 by 120/240-Volt Residential Whole House Surge Protector The 51110 SRG (SPD Type 2) Residential Surge Protection Panel is designed for use on 240/120 VAC at the circuit breaker panel ( the service entrance) in homes, apartments, and condominiums. It offers advanced surge protection for modern electronics and appliances, reducing the rish of damage from spikes and surges entering the property through AC power lines. The leads from the SPD (Surge Protection Device) must be connected to the power mains through a 20 Amp (maximum) disconnect and fusing means. One breaker for each 120 VAC branch. The SPD may be mounted directly to the Circuit Breaker Panel via built in connector which can be inserted in any "knock-out" hole in the panel. Warranty is for the benefit of the original consumer purchaser only and will continue for as long as such original purchaser uses the Leviton "True Whole-House Surge Protection" package. It is a limited 10 year Connected Equipment Protection for up to $5,000. August 7, 2016
Rated 5.0 out of 5.0 by 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. August 15, 2016
Rated 5.0 out of 5.0 by Easy install. The electricians came out and had this in the service panel in about 10 minutes, start to finish. I provided two new 20-amp breakers per the instructions. They did not mount the unit outside the box, it is inside the service panel housing to keep the original wires as short as possible. The indicator lights are both green, so according to the installation instructions, it's working. Will be sort of hard to check, but if I get a surge and nothing works, I guess I'll know it's down. Hope that it will not get tested by the weather, but I'm ready and protected if it happens! Simple, economical protection. August 30, 2016
Rated 5.0 out of 5.0 by So far so good So far, the install of this device was fairly straight forward although I didn't personally install it. My neighbor is a qualified electrician and he did the install along with purchasing the couple additional parts needed to put this with my panel like an elbow, double breaker, and a small box. I would say I'm pleased with how easy it went in as I was with him during the install and it's a pretty basic 4 wire install. I don't recommend self installing without knowledge of panel opening risks or being a qualified electrician. The unit itself looks nice next to the panel and I'm looking forward to the next storm to see how this holds up! August 10, 2016
Rated 4.0 out of 5.0 by Easy to install, hopefully it works! Installation is very straightforward - install a double-pole breaker in your electrical panel and wire the surge protector into it. It was my first time cracking open the electrical panel and it took me all of 20 minutes to install. Would have been even less but I had to move some wiring around. Now, the threaded part that goes into the load center is a bit short. So if your panel is located within a finished wall and it's cover has extends past the panel itself, this will result in it covering the very top of the surge protector. While this doesn't affect the unit, it just looks a little weird. Secondly, Leviton's warranty is for 10 years, but only covers up to $5,000 in damage and it excludes several items - such as A/C units, hardwired alarm systems, and garage door openers. That being said, living in Florida, I do hope it does it's job as we get our fair share of lightning! Since the surge protector is pretty inexpensive, it's worth giving it a shot. August 22, 2016
Rated 5.0 out of 5.0 by A must have for residential electrical protection Leviton Residential Panel Surge Protective device (SPD) is a must have for any residential whole house electrical surge protection, whether from the power company or an electrical storm. In todays homes with more modern home equipment and personal computing devices the need to protect them from electrical surges is a must. Leviton has a $5000 warranty equipment replacement in the event that when the SPD is properly installed and you still suffer from equipment failure due to an electrical surge. That is a good peace of mind knowing that you have a little added insurance if you have an electrical surge event that can damage your home and valuable equipment. August 6, 2016
Rated 5.0 out of 5.0 by Every house should have one This is a great product and will do a great job of protecting you home from an electrical surge from the pole or a lightning strike. The instruction are very easy to follow and this could be a very simple DIY project if you have experience working with your electrical panel, However to maintain the warranty the electrical connections will need to be handled by a licensed electrician. But the security will be well worth the cost! August 3, 2016
