Ty for the video. But. The wire gauge: 10 vs 12 is a total mute. *bc; the 10-gauge handles 600v. The 12-gauge handle 470v. It will trip the main breaker well before any wire/circuit damage occurs. So Gauge wire isn't a "plus" when comparing these 2.
When the device shunts power during a surge I’m more interested in the current carrying capacity than the voltage rating of the wire. Being built to handle more current can only increase device longevity and is still a win in my book. But I agree, both 10 and 12 gauge should be sufficient to do the job of tripping the main breaker.
Agree that wire gauge isn't too critical, but larger gauge is better to reduce resistance. Any talk of voltage and circuit breakers is completely irrelevant. The transients these MOVs protect against are so fast that they are invisible to a normal circuit breaker. A circuit breaker would never trip in these events...hence the need for surge protector
FYI Thecspecvin the Siemens fs140 was only tested with the cable st 6 inches Siemens tech support told me when I asked. He explained that if any longer cable to the panel to shorten cable as much as possible. He slso said to twist the wires from the fs140 uniformly as muvh as possible before connecting to panel if I recall. I forgot exactly what he said butbif I recall, twisting the wires if using longer than 6 inches helped reduce the difference in the spec. I had the data somewhere after talking yltoma seasoned electrical engineer which showed me the Siemens spec was significantly worse in the specs if cable 36ninches versus 6 inches. Of course the Siemens manual doesn't discuss this but I sm positive via double checking with Siemens that the spec is for a 6vinch cable length only
Yes twist wires. BC electric actually run around the diameter of the wire & NOT thru the wire. That's why the Gauge/Amp codes are in place. To small of wire to volt-amps will overheat, conduct & burn.
Yes, Siemens is a government and military contractor in the energy sector (and many others). So, they may not advertise military testing, but the military contracts them to provide energy services.
I have actually seen some of those in solar applications. I hadn't considered them for a whole home SPD though. From a quick search, the MNSPD-300-AC is their 120/240v rated unit. 80kA surge, MCOV 470V, VPR 1200V, 5 year warranty, response time

I was told the fs140 was used on many military installs it does'nt list them because it's classified

Midnight solars SPD?
