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

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

Found the name varistor. I was little I hope mini lathe has one or just power strip in is easier to replace. A varistor (a.k.a. voltage-dependent resistor (VDR)) is a surge protecting electronic

Not the electronic thyristor The one I am? talking about looks like a capacitor anx only has two wires. It spell almost same as a thyristor witch is a type SCR. Dave

I look it up just like a power strip. One time use like a fuse. You can see light to till you to replace. In electronics it was call a thyristor Maybe miss spell. RadioShack wack me $15.00 each back

Looks like plugs in every time to place it by a electrician. 20 years ago that cost $160.00 and hard wire. At less price is coming down. More pain It does not protect against welders only what come

Are those whole house units still only one use ? animal

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

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

What is the best AC protector/stabilator for a 7x14 lathe? There are many types: one for your computer, one for your fridge. Full AC-DC-AC is maybe a littlebit luxury? /johannes

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

I agree They would just steal one and use it . They do not check photo and the just scan backside. Dave

"Seriously ? One thinks that would stop terrorists ?" 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
