As part of some house extension work I want to move the main CU from the garage to a new room (part of the extension) and add a garage CU. The gge CU will be feeding a 3kW rotary 3 phase converter (from class D MCB) and a 2kW 3 phase inverter in addition to the ring and lighting.
Questions:
- are the tails allowed to run horizontally through the wall from the gge into the back of the CU?
- do I have to run the tails to the gge CU from a MCB in the main CU or can I wire them in parallel with the main CU tails?
- the tail length to the main CU will be about 2 metres, what XSA is recommended (100A main fuse)?
- can I run the cables from the new CU horizontally through the wall from the gge into the back of the CU?
