Hello.
I'm fitting a timer onto my immersion heater so it'll run on the cheap rate electricity at night.
It fits on the cable between the switch (just an on/off switch) and the mains.
Looking at the connections where I'll join up the ends of the cable it has five connections in this order (left to right)
SL N N L E
Where the first two (SL and N) are the live and neutral going out to the switch (and on to the tank) and the second two are the neutral and live coming in from the mains. The last one is the earth connection and is set apart from the others a bit (the others are marked by arrows showing which direction the current is going in)
But, if I cut a cable with 3 wires (L, N and E) then I'll have two Earth wires and nowhere to fit one of them?
The instructions make no mention of this - I think they assume it must be obvious. It's not! (not to me anyway... )
Help!
Thanks...
