Thanks Albags.
Sorry I am not explaining - I think that is part of the problem, I don't really understand.
Let me try again.
The imersion heater and thermostat are in place and wired up. The wire from the switch to the heater/thermostat is a standard heat proof cable. It has 3 cores - red, black and green. The current wiring is to a simple on/off switch, which has 6 terminals. Therse are :
Live in (to which is connected the red wire from the house mains)
Live out (to which is connected the red wire leading to the immersion heater)
Neutral in (to whiuch is connected the black wire from the house mains)
Neutral Out (to which is connected the black wire leading to the immersion heater)
Earth (to which is connected the earth wire from the house mains)
Earth (to which is connected the earth wire leading to the immersion heater)
The existing wiring is similar to that you would expect in a standard 13amp plug socket.
So my problem is this:
The new X10 controller has Only 3 connections to which somehow I need to attach 4 wires (excluding the earths which I appreciate have to be connected separately).
Now as I believe I need to wire would be this:
1. Connect the 2 live wires using a connector as there is no terminal on the switch
2. Connect the red from the mains to the "live" terminal in the switch
3. Connect the red to the immersion heater to the "load" terminal in the switch
4. Connect BOTH the black wires (one from the mains, the other to the immersion) together in the switch terminal marked Neutral in the switch
Will this work or will there be a problem?
Is this a little clearer?
