From USA, I read some UK threads about how their timers break. UK Digital timers don't break UK Mechanical break quick USA Digital timers break (in like weeks) USA Mechanical timers last years From my experience UK uses 240v or 220v 50hz and maybe dipole? USA uses 120v 60hz single pole for most things. As far as I know USA uses ground (yes the actual dirt in the soil outside) as a return to power station (not by wire). Please help understanding of this if you know about power return. Power grids are different all over the word. Gadgets like timers might work/break different.
