Hi there, I'm looking for some advice regarding the above, I have a very basic type 'on/off sink/bath' switch on my copper cylinder immersion heater, I want to ad a very basic timer as mentioned above i.e. the mechanical dial types that have push/pull pins etc. the instructions that come with the timer I have attached..........my question is there are two 'live wires' (brown & Black) going to the elements in the immersion, from diagram 2 on the attached can both the 'live wires' be wired/connected into the same terminal in the timer....?
