Hi I'm new to this site im a first year apprentice, just wondering the intermediate switch I had to wire in college for a lighting circuit had L1 L2 L3 L4 isit still really both L1 at the top and both L2 at the bottom.
Also the way in the wiring diagram I seen online it shows both black connect to L1 and both Greys connecting to L2 from the two 2 ways switches but my tutor said to wire them up crossed so grey at top in L1 black second L1 and then black bottom left L2 and grey bottom right L2 the diagram attached is the one from online any help if this is right ?
