Two days ago a lightning stroke our neighbours, so it was time for all-in-the-house Surge Protectors so I went to the local hardware shop to buy some.
Unfortunately the cheapest ones costed 13-15$ which is pretty much for me as I needed at least 4 or 5. I already had connection-blocks and I had to add only the protection.
Why not do it myself? Of course I will and it costed around 2$ per piece. What a bargain? Huh?
Yes, that it 2$ per piece. All you need is a proper varistor (in my case 20N391K) and put it into a nice plug.
In short what you need is:
- a new Plug
- a varistor 250V, ~25ns (example: 20N391K)
Nice job!
3 hours, no more than 10$ and all home connection-blocks are protected from lightning.
Try it but be very careful.
You are working with 220V.
It can kill you if do not take precautions!
this way of connecting , you can make a nice fire . must be put minimum one fuse !
ReplyDeleteChances are you already use surge protectors in other parts of your house. They are also commonly called surge suppressors or power strips. How does a whole house surge protector work
