I'm used to what BS7671...

In what ways do cable cleats transform traditional cable management practices, and what specific benefits do they offer in terms of safety, durability, and efficiency in both residential and industrial applications?

Hi. I'm hoping someone can help with a question about adding a socket as a spur onto a ring mains circuit (rcd protected at CU).
Its a 2 gang socket so max load could be 26A. The 2.5 TE cable is rated for 27A but this reduces to maybe 20A if its in buried in a wall in conduit (as it will be)...

Hi folks,
I have been through the regs. Have a garage wired from a house. Cable runs overhead at an appropriate height and is suitable cable. The distance in mid air is about 2m. My question is does this need mechanical support by way of a conduit or tray. It does seem a bit excessive for that...
