I'm planning to add a remote PIR sensor to an existing outside light. The cable will run 5m approx 3m high along a an external wall so will be inaccessible. I'm going to use 3 core and earth.
Question is, is the usual grey (6243Y?) suitable for external use, or should I be looking for something else?
