Unless I’m careful I find I obsess about things, and it isn’t sustainable. Either overload or burn out on it. Nowadays I try to pace my obsessions, do a bit at a time and enforce breaks, sometimes a few days or even weeks. It allows me to think about the subject, lock things down and make links. Sometimes less is more.
Allows you to remove power from the plugged in device without unplugging it. This provides convenience to easily and quickly turn things on and off and prevents arcing when unplugging. 240V 13A can arc a bit, particularly if unplugged under load, or on older sockets where the contacts have worn. While a little arcing doesn’t do much damage immediately, over time it will cause pitting and make a high resistance joint that will generate heat.
The switch only disconnects the live terminal, but the neutral terminal should be similar potential to earth (depending on how the building is wired).
Truly the king of plugs and sockets. The plugs are individually fused according to the device needs, ergonomic to use and exciting to stand on.
