The new home cost of solar adds $10,000 per news
Pocket-change in California. ? Broker commision is $50K and taxes are $30K per year. ? ? ?Ther are no new homes for under $1M, and very hard to find for under $1.5M. ?But still they sell very fast as there are an unlimited number of buyers who can afford it or more. ?Near me by the beach, 3X to 5X higher. ??
Then that $10K upfront investment saves you $100 per month on the electric bill, that is a fast payback and then for the next 15 years you make $100/month profit. ? Most people will opt for a larger system and spend closer to 20K so most of their electric bill is covered.
About what is covered? ?A surge protector is wired in PARALLEL to all house wires. ?It is not wired in series. ? So YES, it DOES protect against internally generated surges. ?In fact, placing a 200A protection in your panel box would offer some protection to neighbors who share the same utility pole transformer. ?(limited by resistance in the wires). The device clamps the rails in the box to some maximum voltage. ?It would 100% certain stop the surge from jumping across branch circuits Dave?

Yes, like I wrote earlier, that is a MOV - Metal Oxide Varistor and they have either two or three leads. The ones with three leads can be used to indicate when the MOV has blown. The ones with two leads are a crapshoot if they are still good, depends how they failed.
Most surge suppressors use MOVs. The biggest problem with MOVs is that the clamping voltage is really high. A MOV with an AC working voltage of 130VAC has a clamping voltage of over 350V, so you can still blow the electronics out.

A varistor (a.k.a. voltage-dependent resistor (VDR)) is a surge protecting electronic component with an electrical resistance that varies with the applied voltage.[2] It has a nonlinear, non-ohmic current–voltage characteristic that is similar to that of a diode. Unlike a diode however, it has the same characteristic for both directions of traversing current. Traditionally, varistors were indeed constructed by connecting two rectifiers, such as the copper-oxide or germanium-oxide rectifier in antiparallel configuration. At low voltage the varistor has a high electrical resistance which decreases as the voltage is raised. Modern varistors are primarily based on sintered ceramic metal-oxide materials which exhibit directional behavior only on a microscopic scale. This type is commonly known as the metal-oxide varistor (MOV).

That Square D unit is a MOV device and whether it is single use or so is dependant on the surge it handled. There is a lamp on the from which will indicate it must be replaced as the MOVs are shot.
I spent a lot of time working on surge protection in a prior life and _all_ MOV (Metal Oxide Varistor) devices will have a lifetime based on the number of surges it has handled. The more and the higher the surges, the shorter the life.
We ended up using a different device:
They are not cheap, but we were installing them in places where we had lots of lightning and we had cameras up on metal poles. Just the voltage gradient of the storm cloud was enough to blow up equipment and a strike was enhanced because we had metal poles 30ft into the air.
MOV suppressors lasted only partially through a storm and then you had to buy a new one and sometimes replace the gear on the pole. The Brick Wall units lasted for years and we didn't ever have a failure from them.
HOWEVER, it you want to protect your lathe or mill or any other shop equipment, a power strip with MOVs will usually and reliably do the job. And, I like that it has a dedicated switch which makes me have an extra step to make sure I have started up safely.

retrofit. ?But if you are going to worry about protecting stuff,
you might as well just do it once
These devices are easy to install into an old panel and
because they are required, they are available “everywhere”. ?
?Just put one of these in and be done with it and it will cover
your TV, computer, power tools, car charger, and whatever.
There are two basic kinds, one snaps in like a larger size
220 volt circuit breaker and the other screws into a knockout.
OK, but you really wanted a AC-DC-AC system. ?You might be in
luck because that is how all brushless motors work. ? There is
one of those inside the lathe already if you have a brushless
motor
But if I am not mistaken, I think all mini lathes use PWM to
control the motor. ?If so, then you already have a kind of
AC-DC-AC system in from of the lathe's motor.

The “best”? ?The latest electric code (here in the US, the NEC) has taken all the fun out of this. ?All new service entrance panels are required to have “Whole House” surge protection. ?This only applies to newly installed panels in new construction or retrofit. ?But if you are going to worry about protecting stuff, you might as well just do it once

Use one for TV or computer.?
I like switching off the power too.
Lighting , power surge and solar storms can take out electronics.
A solar storm in 1859 took out telegraph stations this before electronics.?

Re: Mini Lathe and Northern Lights
The Carrington event was a huge storm.? Estimates vary on the X
class flare for that event. Some estimate it was an X20.? Some argue
the storm in 1921 was larger. By comparison the recent flare which
created the huge geomagnetic storm was X 5.8, I think.? A few days
later there was an X 8.8 flare that wasn't directed towards Earth.?
There has been larger flares in the past that weren't directed
towards Earth.? Another solar flare like the one during the
Carrington event would likely destroy most all solid state devices
and create mass chaos since we are so dependent on tech nowadays.?
Vacuum tube equipment would survive though.? Yeah, we are way off
topic.
Stan, an amateur radio operator in TN.? Yeah, I have some vacuum
tube equipment :)

If think nothing happens try the solar storm of 1859
The storm would take out plug in mini lathe control board.
I have switch that kills all power to my hobby shop.?

Re: Words you can no longer use at FedEx shipping mini lathe parts
I agree
They would just steal one and use it . They do not check photo and the just scan backside.?

No, it wouldn't stop them but it would let authorities know who the terrorists were. (Or at least the dumber ones. The smarter terrorists would have forged IDs).

I was down FedEx shipping.
The want my driver's license.
I start ask why I stop short .
They keeping track just in case.

I did not use the B work.
It used talked the gifts we gave Germany in 1940's it ok.
