Power surge parts list Question.

[Happytobehere]

In this Youtube vid

the poster mentions a part called a MOV but doesn't mention the specs of the MOV so I could know what to purchase to build the surge protector. Could someone be so kind to figure out the part number of the MOV so I would know what to purchase to complete this project. This project is of course for a 120 volt US AC household outlet project. Thanks so much in advance for any and all help with this.

Any of these should be OK (as well as many others).

You need a type with a working AC voltage rating of around 125V.
The higher the peak current or joule dissipation, the better the protection - the larger the power spike it can withstand without failing.

These are pretty high ratings, without going to stupidly expensive ones:

Thank you so much. The reason I'm putting together such a device is I've been trying to use an electronic security device at the end of my driveway https://www.homecontrols.com/X10-Powerflash-Security-Interface-Module-PSC01-XPPSC01 and a power flicker zaps them every month or so. At $25 to $35 a pop its getting expensive, Your help has saved another person (me) a lot of aggravation and money. Thanks for your knowledge, time and kindness..

I need to ask you a question:

Do you happen to have a furnace with an ECM blower? Carrier is a good example. Does your driveway monitor not work when the blower is blowing?

If the answer is yes, then an electrical filter needs to be placed on the furnace. I have to locate the p/n.

Me: X-10 device
Carrier 58MVB furnace

After loosing a couple of X-10 modules and them not working when the blower is on, I did upgrade to UPB, but did not finish the upgrade,
The UPB module is still working.
