Hi. I have a shed with its own small consumer unit connected by underground SWA to a connection box on the outside wall of the house. This in turn is wired to ts own MCB in the consumer unit of the house. I am going to erect another outbuilding some distance away from the shed. SWA for this was laid a couple of years ago (size was per recommendation of a qualified electrician). I plan to install a small consumer unit also in the new outbuilding. My question is: Can I connect the new SWA cable to the same outside connection box along with the existing shed or do I need to wire separately into the house consumer unit via a separate MCB?
