Hi
I suppose this post is referring to big AC circuits rather than small battery DC circuits but I am hoping some of you clued up folks can enlighten me.
I was recently considering taking a spur of my socket ring circuit for a new plug outlet in a large space at the end of our hallway. While learning how to do this correctly it has given me a fair interest about the layout of the electronics in my home and how it can be altered.
I'm pretty new to understanding AC but have quite a good idea of the distribution board and Breakers etc and how it all works.
A few things still confuse me. When I look at all the RCBO switches on the bus bar.. I notice some are 16amp for the lone circuits then like 32 or 40 amp for bigger circuits.. my confusion is this
if the main service cable entering the property carries all the current into the meter then comes out the meter powering the busbar which carries the full load supplying to the RCBOs.
Well If the entire load being pulled by every breaker together adds up to more than say 16amp, does this then mean that the current in the busbar and mains cable entering the property is also above 16 amp... and if so HOW does this not effect or trip the 16amp RCBOs on the same busbar ??
I assume I am missing something about the workings of AC... if somebody could help me with this confusion Id very much appreciate it
cheers
