[hope this isn't off topic for this board]
I'm doing a DIY electric board for my terrarium: in case something goes wrong at least the whole electric circuit won't switch off.
My current setup is a C10 breaker followed by a main on/off switch, and then an on/off switch for every power outlet. All switches have a light to show if it's on or off.
Red is "phase", Black is "phase" returning from switch, Blue neutral and green/yellow is earth. The light for switches have a black cable. (*) These are the French standards, and the board will be plugged in a French power outlet (230V AC, 50 Hz).
Question: I think that a C10 breaker is too much. I'm thinking of putting either a C6 or a C2 breaker. From where to where do I mesure the current total instensity when all appliances are on?
(*) Sorry for my lack of lingo, but google translate didn't help much.
