PE from metal back box to socket

[Paul228]

Have things changed and I missed the memo.
Let's start by saying I'm a fossil. I was trained the old way, were u went with a mate and went to night school and day release. Anyway, was on a domestic fault for a mate of a mate. I rocked up, kitchen ring tripping. Asked any recent works, holes drilled etc, non was the reply ( which was a fib, but no matter). Took both legs out of the board, circuit breaker tests ok, ring has 48k short. Went to split the ring mid point and noticed no earth strap from the box to the socket ( in my day this was mandatory). Found fault, someone had fitted an outside socket, full of water. Anyway back to the internal metal back box. The ring was in a new extension, one year old. So I advised them to get the sparks back to fix it. A few days later, customer rang me and said the sparks said it's not a requirement anymore. My question..since when

Why are folks getting so excited about adding the flylead if its a metal accessory?
I can kind of understand if you mean when replacing a plastic light switch for metal, and cpcs were already terminated in back box, easier just to add fly lead, but in every other instance I'd always prefer to run cpcs direct to accessory, and leave it at that.
For some reason on metalclad surface mount gear I always fit a flylead, but tend not to bother with flushboxes. Beginning to question the logic with that but there you go!
