    Probably a dumb question but...

    Voltage tester question

    If you used a voltage tester to touch L-E does it allow the 230V to actually flow to earth or does it use a smarter means of calculating voltage without requiring a current to pass? In theory, could you damage a connected item downstream?

    Possibly the most bizarre question I’ll ever post……

    ….. but does anyone have any kind of idea what a safe touch voltage would be for a cat?! I’ve just thrown some led fairy lights around our cat tree (you know, just because….) and had assumed that they’d be 12v or lower but glancing at the psu as I plugged it in and it’s a secondary of 31v (3w)...
