SAFETY!!! How can I earth a Sinotimer programmable timer (TM618) inside a metal box ?? Answered
Hi, I am in the process of constructing a retro console timer for my 10yo grandson (for his parents really). They only want the power to the console on a predetermined times. I found an idea on Instructables which is basically a programmable 7 day timer in a small (lockable) cash box.
Question: there is no earth tab on the input side of the timer and I want to earth the box because it will contain 240v!! Is it as simple as wiring the wall plug with three core cable and attaching the spare earth wire to the inside wall of the metal box? Please advice.
