First questions of many for those electrically gifted members:
1) I'm wanting to go down the Din rail route. Planning the basic layout and will use MCBs for each individual low power circuit (ie the PIDs, timer, pumps) in order to isolate and detect any fault in the future. Instead of having a live bus is it easier to use a mcb bus bar and connect them together so that the mcbs become the hot bus, rather than having din mounted terminal blocks supplying the live for each mcb?
2) Wire sizes. Please can someone sanity check this for me. I will have a 30A breaker from the garage into the panel. Power in will go via a 62A contactor (overkill I know) and will use 6mm2 cable for the wiring drawing up to the 30A. Stepping down from the MCBs/hot bus I'm thinking will 1.5mm2 be sufficient?
3) What mcb protection have people opted for? I was going to go with 1A for each PID and then 4A for each pump (one riptide and one Chinese mag pump).
Thank in advance
