Hi guys, need some advice here.
I just bought a new switch for my water heater. There are 2L2N and 1 symbol like wifi which I think it should be G (5 holes in total).
When I open the old switch, I realise that there are 2 black, 1 blue, 1 red and 2 green wires.
Should I just connect the 2 green wires to G?
Wiring guide : 3 color wire (green, blue,black), Which one neutral, live and earth
