Installed outside lamps using 1.5 SWA. The outside wiring is connected to a light switch located inside the house. The 1.5mm T&E from the switch is connected to SWA cable within the house using appropriate jointing box and cable glands. I have only just realised that the downstairs lighting circuit that I am connecting the outside lighting to is not connected to the rcb in the consumer unit. The RCB in the consumer unit only protects the socket circuits. Can I add an RCB to the downstairs lighting circuit to offer the required regulation protection to the outside lighting circuit I have just installed
