[QUOTE="binky, post: 122665, member: 490"] Right so its just a main switch then and the individual circuits are 'fused down' accordingly. The 1200A thing is just its load capacity ie its big enough to carry total load for the system and still operate as a switch without melting - its the same as the 100A main switch in standard domestic CUs, you don't get a Zs based on the main switch, but on the individual circuits, you take Ze at the main switch. If the panel is a fed from another panel (ie by distribution circuit) then you need to check the feed panel for a suitable 'fuse' to protect the cable supplying your panel with the 1200A MCB. I hope that makes sense :^O [/QUOTE]
