I'm powering up an outside office and greenhouse heating and have established I need a 10mm SWA for the load and distance from the house to the locations. Inside the house I plan to run 10mm twin & earth from the consumer unit to the wall where it meet the SWA. What would be the best connector/junction box to use between the two types of cable? ![Confused :confused: :confused:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
