## Description

Siemens believes today's residential surge protectors come up short when protecting today's modern home filled with smart appliances and electronics. This is why we developed our first surge commercial class total home surge protectors. When there is a problem, Siemens first surge takes the guesswork out of knowing when it is time to be replaced. What will you see and hear when this occurs? audible alarm: beeps green led(s): extinguish red service light: flashes first surge is also ground referenced monitoring-equipped notifying if you have a rare safety hazard exists due to a compromised electrical system neutral to ground bond. What will you see and hear when this occurs? audible alarm: beeps green led(s): remains lit red service light: flashes.

Review: Siemens FS100 - Peace of Mind for the Electronic Home - I did a lot of research on surge protection before settling on this particular model. I chose this one for 4 different reasons: (1) It is made to be mounted indoors or outdoors and my main panel with circuit breakers is outside on the back of the house with a sub panel inside. (2) Siemens reputation for quality, excellence and innovation. (3) It has 4 wires for hookup so it covers surges from both both line phases, neutral and ground. Not all surge protectors do. Look for L-N, L-G, N-G and L-L. (4) LED indicators let you know when surge protection has been exhausted due to an event or if your grounding has been compromised. This particular models protects against surge spikes up to 100,000 amps. That is enough amps for 500 homes like mine! (for an extremely short time anyway). Before I go any further, I should emphasize that if you do not know exactly what you are doing, you should not attempt to install this device. Your life is worth the $100 or so dollars that an electrician would charge you to install it. Not to mention, if you ever have to make a claim on the guarantee from Siemens, you will need to provide a receipt from a licensed electrician having completed the installation. That being said, installation is not difficult if you know what you are doing and plan ahead. The 4 wires come through a 3/4" female threaded conduit inlet. I had limited options for where to attach the protector. I had 1/2" knockouts available on the bottom of the box, but because of other conduits I had to use a 1/2" offset nipple with a 3/4" x 1/2" reducing bushing. You can see this in the pictures. I used some silicone sealant and a rubber washer to make sure the connection was weatherproof as required in the instructions. Because of this offset nipple, the wires are a little longer to reach the required connections, but still shorter than the supplied length. The shorter the better, but keep the wire bends smooth and untangled. I was careful not to damage the wire insulation when running it through the nipple and rotating it until tight. Do not attach the wires to an energized breaker. Make sure it is off and verify with a circuit tester. The black wires attach to a 2 pole breaker which covers both phases coming from the utility pole. Since I installed the protector on the main breaker panel, the neutral (white wire) bonding strip is connected to the (green wire) grounding strip. If the panel were inside the house, the ground and neutral would travel separately until coming together outside to go to ground. After triple checking my work, I turned on the breaker and was greeted by 2 green LEDs verifying both phases are protected and ready for use. I am very pleased with the product and the installation went smoothly. I only wish the directions were more detailed, but I believe this is probably to discourage unqualified persons from thinking they can do this themselves. I would not have attempted this installation without doing my research and making absolutely sure I knew what I was doing. I hope I never have to find out how well it really works, but if I do, I will write an update. Just a little side note: This thing is pretty bright at night. Looks like I have an alien power source.
Review: So far, so good - Good: Installation was reasonably easy. The line wires connect to dedicated breakers, one on each bus, which I picked up from Lowe's along with a conduit nipple and nuts for a few $s. Positioning of the surge protector and the breakers it connects to are important: these things operate so quickly that the position of the breakers and the length of the wires running to them make a significant difference in the unit's response time. The shorter the path from the main to the surge unit, the better. I rearranged the existing breakers so the new ones would be the first ones downstream of the main, and positioned the surge protector next to them outside the box so the wire run is only a few inches. Wiring from there was straightforward: black wires to the breakers, white to neutral, green to ground; put everything back together, power up the mains, make sure everything's in order, and turn on the surge unit's breakers. Elapsed time, start to finish, was about an hour. There are status lights on the unit that tell you that it's wired and functioning correctly, and lights and an alarm that tell you when something's wrong - nice touches, and one of the reasons I went with this Siemens unit. Bad: The only real problem I had was that the conduit stands out rather far from the unit's base; I had to elongate the knock-out hole on the box about 1/4" with a Dremel tool to get the unit to lie flat against the wall. I don't know whether the issue was with the unit or the box. Ugly: The installation instructions are NOT detailed, clearly written for professionals. (Although, the instructions do advise you "do not install this device during a lightning storm." I'd think a pro would know that.) This isn't necessarily a bad thing, as mucking about inside a breaker box is a very bad idea unless you know *exactly* what you're doing. If you don't understand the instructions, or you're not experienced and comfortable working with line power equipment, get an electrician to install it. It shouldn't cost a lot. Bottom line: I was motivated to buy this by the realization that I have a LOT of electronics in my home. The obvious stuff is surge protected, but the vast majority is not - who thinks to plug their washing machine or alarm clock into a surge protector? Yet, one big lightning strike on the pole outside could kill all of it. This Siemens unit isn't cheap, but it IS cheap insurance. Unfortunately, there is only one way to find out just how well it works, and I'd rather avoid that. For now, however, so far so good. Five stars.

## Questions & Answers

**Q: Do you need dedicated breakers for this or could you just use existing one**
A: You really should put this on a dedicated breaker.  Double tapping a breaker is never a good idea and, in some states, it’s illegal.  Be safe and use a dedicated breaker.

**Q: which FS(060,100,160) Use in india for house protection .**
A: The number here corresponds to the capacity of load when picks arise.  # 60 will protect you from a 60,000 Amps surge and #160 from a 160,000 Amps surge.
if the house does not have too many high consumption appliances, 100 should do.

**Q: Does this protect one circuit or the whole panel?**
A: It will protect  the whole panel .

**Q: Does it work for 220v/110v braker? 65 amp consumprion.**
A: The device has four wires: two hot, one neutral, and one ground. A 20 Amp two-pole breaker is recommended. That is what I used.

### ⭐⭐⭐⭐⭐ You need this whole house surge protector!
*by R***S on June 3, 2018*

Works as expected!Like many of the other reviewers, I did a lot of research before settling on this. I installed it after losing about $3000 worth of electrical equipment and appliances after the power company dropped the neutral line into my house. If you study the electrical theory involved in this, you'd buy one and install it immediately. It makes a lot of sense to put this device in and protect many, many other sensitive electrical and electronic equipment. There are a number of brands on the market. They all do the same thing. This unit is a bit larger and has more capacity. That's good. If you get hit with a lot of electrical storms and such, it will eventually burn out, but you can replace it. Meanwhile, it have provided significant protection. Installation is easy, straight forward, and logical. Nevertheless, have a licensed electrician do the installation so that you are covered. I'm really goad I installed a surge protector. I'm equally glad I got this one.
