second supply taken from cu incoming

[davidjones89]

been to a property today to do a pir, on visual inspection of the garage( the garage had a dedicated metal clad cu suppling two circuits, these were lighting and power circuits) a second cable (swa) is taken from the incoming tails of the cu to an out-house with another cu supplying two circuits, again power and lighting. is this deemed acceptable ? plenty of room for conductors in garage cu incoming with supply cable being 6mm swa, same cable as second supply to out-house. supply to garage is taken from meter henley block, opinions welcome please,

Any tails from the supply incoming should have a dedicated switchfuse if they are longer than 3 or 4 Meters and are not taken from a dedicated MCB from the CU.

Nothing wrong with the garage db, its less common these days, but not unheard of.
As Jason said, henley block should feed a sw/fuse, then feed the garage.

Might need to consider earthing arrangemets though.
