Thinking about upgrading my attached garage wiring using 20 mm conduit to run a ring circuit as well as a lighting circuit, both from the house consumer unit. Due to the shape of the garage and the location of the existing wiring, I may have to use one or two junction boxes at various points (32A Adaptable boxes with 5 terminals, which I have spare).
Is it allowable to use the same junction box to carry both lighting and mains circuits using the 5th terminal as earth for both circuits?
Many thanks in advance for any opinions
