I would like to run a swa cable 2.5mm2 from a 16A MCB on a 30mA RCD protected CU to my shed (5m away) and connect to a junction box in the shed to power a double socket, an inside light and an outdoor PIR light. I am planning to have everything to IP55 or more.
- Would I need to have the 2G socket RCD protected? or change the MCB for a RCBO?
- Is the swa cable ok as a radial circuit or would I need to have it as a ring circuit?
