    Hi.

    Does the light on a surge protector use up much electricity if the e.g. 4-socket adapter was always left plugged in? Example in image below.

    no, it uses an absolute miniscule amount. If left on all year would hardly amount to 1c

    Looks like a standard distribution board to me. Is there any indication of surge protection on the back?
    Anyway , as above, the load is insignificant.

    You're right. I wouldn't be depending on that to save any of my equipment. It's just a normal powerboard.

    Hi Cerco & aido79.

    I just used that image as an example. I use a proper surge protector with 4 sockets.

    Don't expect your equipment to be saved if lighting strikes as it won't. Better to disconnect everything you care about if a serious storm is approaching. I believe these things are a bit of a con.

    They're just a few extra passive components to suppress transients and swells. They won't protect you from lightning, they're more to keep them spidery silicon lookin' bits of your electronics happy.

    M1 - M6 are Metal Oxide Varistors
    L1 and L2 are inductdors
    and G are Gas discharge tubes.

    That's a fancy one, the cheapo ones might just have a MOV or two.

    Industrial ones have a fighting chance.
