depends on what you mean by "overloading".
if you put too many consuming devices on it and thereby overloading it, it will just fry but not the consuming devices. they will just not get enough juice to run
if you put too much current into the circuit and thereby overload the extension, there´s a very good chance, you also fuck up the consuming devices.1

Yes, sometimes, and also Cause a Fuse to Blow, @Notyourdreamgirl.
I nearly got Electrocuted the other night for Screwing up something with a Simple night light.
Thank God the Circuits are still Working, the Light as well, and all my Maintenance man had to do was Push a Button to Fuse up so I got Electric again on the One side of my apartment.
Good luck. xx
