Electrical Wiring in the Home/Whole House Surge Protection


I had a whole house SPD installed about 2 months ago. Square D, SDSB1175C Series 3.
The other night the main power went off (heard a loud pop) for about 20 minutes. When the power came back on there was no electricity in the living room. Checked breaker panel and found a 20 amp breaker had tripped and blown (red line).
Had electrician replace 20 amp breaker. The new breaker kept tripping. Further investigation revealed that my surge protector on the living room TV had tripped and shorted. Unplugged TV from its surge protector and everything back to normal.
Asked electrician how all this happened? I thought my SPD was suppose to prevent? Asked how the SPD interfaces with the breaker panel? He said he does not know, only that it works?
My question, something does not seem right?
I think everything worked except the SPD?

I read this twenty times and yes I agree with you,   remember   or be aware   a whole house protects or is supposed to protect from external surges,  but to protect every device as best possible you need the whole house protection,  then you need individual protection for each device,   there are internal surges generated from many sources,      the best bet is a UPS on each device or multiple devices that in total fall under the rating    

This is getting to be more and more a problem the more devices we all have in our homes,   a whole house is great   but if the fault or surge is not external to the whole house it does not work in reverse     

UPS devices are the best because they contain an isolation transformer,    

In other words if a power strip plugged into an outlet failed,   the whole house would not detect that       that is where the confusion on what it protects comes from,  

Personally I like to use Furman power conditioners       they are very sensitive to internal faults, provide real time voltage levels in the form of a digital display and are not expensive compared to the protection they provide,      I get mine at like Guitar Center,    devices designed to protect musician equipment,    which can be very very expensive,     

I actually use a whole house,  then a power conditioner,  then a UPS on certain devices,     

But trust me, if there was a fault or surge generated on the load side of the whole house   it is of no help,  breakers protect wire, not devices,     another reality most are unaware of,  

I would be looking into some individual protection for each device      it is a pain, but the technology is advancing so fast     most are not keeping up,      people have thousands of dollars in these ipads and other devices to charge on unproteced circuits,    the devices get smaller more costly and less protection         many want to avoid the mass of devices because of aesthetic reasons,

But each device needs it's own protection from internally generated surges, and a shorted device in front of a TV would be an internally generated surge,
