Whole house surge protector

These things look impressive but often only have a couple of 30 cent MOVs in there. In better electronics, those MOVs are often accross the power line anyway.

Problem I have with all of these types of devices no matter the size, brand or style is.....

How do you know if it worked?

You can have a hundred storms go by and never take a damaging strike. How do you know if you just never got hit, or if you did and this device protected you? If you do get hit and take damage, how do you know if the device failed outright, or if the strike exceeded the device's capabilities? Yes, I know some of them have indicators to let you know protection is 'active', but they still don't let you know if they ever took a strike and protected you.

I had one for the pump in a place I was renting and I knew when it had done it's job. One night we had a fierce thunderstorm go over... I usually enjoy them but this time I was scared witless. (or something. )
The next day I was doing dishes and when the pump kicked on the suppressor went off... it sounded just like an arc welder. I wasn't long pulling my hands out of the dishwater, then realized what had happened.

The thread got me thinking and I spotted the surge suppressor while cleaning my shop today.







So Bob's your Uncle, smaller footprint, I didn't need the Telco or COax protection and now it should be installed in a year or two.

I have a Siemens FS140 on my shop and one on the house. Each is a 200 amp feed off of a 400 amp service. Ive sold and installed many of the Siemens FS140痴 over-the years. There is also a flush mount kit available if your panel is in a drywall壇 environment.

funny thing is Amazons crazy pricing has the fs140 cheaper than the fs100 and its a far better unit.

Thanks everyone for the comments. My search also led to this thorough but a little dated article:

What's the "Best" Whole-House Surge Protection?

One of the most important things is to make sure your connections & the grounding of your main system is good... with out that these other systems will not work correctly... Also that the Intersystem Bonding Terminations are done correctly (or at all)...

We have been using Transient Protection Design (TPD) components on both our commercial & residential installs for the past 7+yrs. We design & install low voltage control systems for automation, lighting, HVAC, access control etc. (we are not electricians)... I'm sure Square D (I'm a fan of their load centers), Leviton, & companies a like all make good products (& are probably cheaper)... I will say we are dealers for TPD but because of our success with the product... not because we have to... (we are also dealers for Surge-X, APC, Liebert, etc)... I have 2 TPD TTLP units in my own home, plus the low voltage protection devices they sell by choice.

We started using these systems do to issues with a control system at a medical facility in which we were seeing unexplained intermittent issues & premature failure of some components. After installing all issues resolved & they are one of our best clients to this day...

TPD has components that cover everything you described... plus. When companies that are completely unaffiliated to them like Lutron, Crestron, AMX, ELAN, etc suggest (or even recommend) their use it say something.

We use the breaker panel units & low voltage pieces on many of our projects... zero failure rate in 7+ yrs. Just another option...

Here are some links to the product & some info:

Here in western Arkansas, it seems that rain is always accompanied by a thunderstorm.
I have a whole house surge protector and also individual surge protectors for each outlet
that anything electronic is plugged into.

However, if you want real, certain protection from lightning storms, then
UNPLUG EVERYTHING ELECTRONIC when a storm is in your area !

This action will remove all paths for the surges, even the ground wire.
This includes things like dishwashers, microwaves, even these newer
refrigerators that have circuit boards.

That's why I even have a 120V submersible pump for my well.
The pump gets unplugged as well, even though it also is plugged
into a surge protector.

There isn't a surge protector or ups made that will withstand a direct lightning strike.

We used to live in an area that had highly mineralised ground, a lightning strike about 100m away killed almost everything in the house via the earth connection except a rubbish fax machine that I wished would die, it was the only thing I got to keep.

I hope you have a good supply of thermal paper rolls. lol

This was many years ago when thermal rolls were state of the art, haven't seen one of them in years.
