Consumer Unit Change Video. Nice.

Zoomup
I liked this video because it is well filmed, has no loud music, and the sparks is very pleasant and explains things well. With plastic conduit I cheat and use manufactured elbows and bends sometimes because they save time and are very consistent and neat. What do you think?

    It's not a blob of solder. Its usually either a thyristor or a gas spark gap thingy.




    Err, it is normally a transorb or varisitror  ( this sort of thing )   Spark gaps have the problem of staying in arc once struck, and are more suited to higher voltages, or smaller gas filled ones on LV when you do not mind the fuse being blown.
