If you have a 10mm2 SWA that needs to come back to the main consumer unit but it would be a nightmare to gland into the consumer unit because it only has the Hager Square knock outs - would it be acceptable to terminate the SWA into a switch fuse then run a 10mm2 T+ E back to the board on a MCB.
I know it's probably best to do a submain via Henley but is there anything wrong with doing it the way above. The SWA supplys a mini RCD unit in a shed so my thinking would be that the 10mm2 T + E from the switch fuse to the house consumer unit would’nt need RCD protection as the T+E would be clip direct and the SWA from the switch fuse to the shed is mechanically protected.
Thoughts?
