Earthing an immersion heater switch.
So I already have an immersion heater, operated by a simple on off switch with a red light to show it's on.
I wish to add an electronic timer before the on/off switch (assuming 240v supply -> electronic timer -> existing on/off switch -> existing immersion heater)
& I have chosen a Timeguard NTT03 Linky.
But after reading reviews it would seem the timer has no earth terminal. But obviously I dont want to break the earth connection, so I was wondering is this the right thing to do?
I'm thinking the earth wire (from 240V supply) into this terminal on this specific back box, & then the earth wire that continues on into the existing on/off switch into this same terminal
Or have I completely misunderstood it, bearing in mind I'm no electrician.....
