Fredrik's system.

[octaviars]

My little project continues, the cable from my cabinet where the rack is are in the fusepanel and the cable that goes to the meterbox is in place.

The phase will go through the maincuircuitbraker and a Klangmodule in the fuspanel (a fourth pole will be mounted on the maincuircuitbraker for this "hifi" supply), zero and ground will be connected to isolated connections so no connection to the zero and ground feeding the rest of the fusepanel.




In the meterbox the 30mA earthfaultbreaker (RCB) is going to be placed for this spur. The 4pol RCB is a 300mA that is on the supply to the fusepanel in the house for preventing fire (all groups that need 30mA has that in the fusepanel (they are called JFB1,2 and 3 in the picture above, only JFB1 is visable). Here is also a overvoltage protection installed to prevent damages from thunderstorms (not a direct hit but spikes on the net)
