1 Would like to know how many twin and earth wires can be connected to a 15A c/breaker
if the c/breaker does not get overloaded is there a max that can be connected on a singel c/breaker.(i thought was max of 3)

2. If a house is wired with win and earth an it loops in the light switches will/must there be a spliter boxes in the roof space? (could not see the use of it unless u want to change the posssion of say a light switch>)

3 How many plugs can e connected to a 2.5mm twin and earth 20a c/breaker.(always thought there was no limed as long it does not trip)
