Trying this on hot summer day Before turning on your ceiling fan and? using your mini lathe.? Check your cell temperature and room temperature at the mini lathe even try floor. Big surprise Dave

The varistor is good to know about it some many things today It dates back to 1927 but did see any electronics till 1970's now it almost everything including the mini lathe controller

Thanks Buffalo John for your good lesson, I learned news and refresh old knowledge that was lost. With few words: Ground cable is important, and it have to be

I agree power strip with surge protection inside is best way go and turn off power before you leave your hobby shop. I to have lights on strip and all power tools it also to stop fire. Just think of

I agree It is part of a mini lathe But it is also part of lot of electronics. I said in beginning? I found a power strip is best way to go for mini lathes and all other electronics. Some do wonder

You guys are all very knowledgeable, but aren't we getting a bit far afield from minilathes? As for me, I have my machines and lights in my basement shop plugged into a power strip above my workbench

Here is a schematic use on mini lathes and most electronics . The biggest problem is it on board and remove.? If was by fuse it would real simple to change out. Dave

I do live in California so know all probles . I also look into solar. The only way pay if you install your self and it used off grid. Dave

Thanks John animal

It's not the design, it is the device. A transient pulse needs to be dissipated. To do that, the MOV becomes a short and then when the voltage decreases, it can become a high resistance path again.

In technical terms the Varistor shorts out? (when a voltage spikes happen) flipping the breaker or burning out the fuse. So if not designed right you easly have fire because it gets very

?Surge protectors aren't all equal . They said on the news just now the fire was started at one of the surge protectors for a 3D printer I believe

See my answers below in red: When in doubt, keep it simple, make sure your protection devices have all the proper connections to work, make sure your building wiring is strong enough to support your

Here part cost $0.15 each? Shipping? is around $6.00 so buy more than one for next time. The good news about part is only voltage you look at for most electronics. If you use whole like use for

The Varistor use today every where today beyond the mini lathes and DRO'S.? They are not plug in like fuse. It is found on the other side of fuse or breaker. You have disconnecte to test the

I first found part on a Bridgeport mill DRO. The DRO die and found this part. The DRO was new in 1980 A pain to replace. Today I would just cut part onto and use power strip. It still in my mini

AC is an important subject, and I thank for all input. Please keep on teaching us: Most of us know that the Earth cable (GND) is important. However, many (include me) dont have it in the workshop.

1. MOV failures are *usually *short circuit, but it depends on how much energy was diverted. If a lightning strike occurs, it is possible for there to be multiple short duration pulses with
