According to BS7671 definitions that is. (Note 2 - "RCD includes devices such as RCCB, RCBO, CBR and, MRCB".for the uneducated that is

Wow…. I wasn’t expecting that…
But then, no one ever does……
“Nobody expects the Spanish Inquisition! Our chief weapon is surprise... surprise and fear... fear and surprise... Our two weapons are fear and surprise... and ruthless efficiency.... Our three weapons are fear, and surprise, and ruthless efficiency... and an almost fanatical devotion to the Pope... Our four... no... Amongst our weapons... Amongst our weaponry... are such elements as fear, surprise... I'll come in again.”
For a running gag this one was was better than most!Nobody expects the Spanish Inquisition! Our chief weapon is surprise, surprise and fear, fear and surprise. Our two weapons are fear and surprise, and ruthless efficiency. Our three weapons are fear and surprise and ruthless efficiency, and an almost fanatical dedication to the pope.
Tell the kids of today that they’d sell you 7 pints of lager in one can for convenience… and they wouldn’t believe you!Party 7 now not heard that for a while.
Not heard that for a long time - thanks! Time for a new profile pic I think....Then there was bleedin' Watney's red barrel...
Keep the questions coming - it's what this place is here for!I know I am a trainee but what is Del on about when he is talking about staggering a ring in a kitchen @38mins45secs in the video. The other guy he is talking to looks confused as to what Del is saying

In this case it's far from obvious and he didn't explain it brilliantly.
It's basically a way of wiring a ring using short lengths of cable between every other socket. It's often used (by me at least) in commercial trunking and conduit systems.
e.g.
CU - 1 - 3 - 5 -7 -9
9 -8 -6 -4 -2 - CU
While you could go CU -1 -2 -3 -4 -5 -6 -7 -8 -9 and then have a massive unwieldy run all the way back the CU, the loads would then all be one half of the circuit and purely practically it's much harder to do!
His point (I think) is about having the loads not all concentrated in one spot on the ring. The wiring scheme above can balance things around the ring more.
It's good that Del after 40 odd years is still learning.I know I am a trainee but what is Del on about when he is talking about staggering a ring in a kitchen @38mins45secs in the video. The other guy he is talking to looks confused as to what Del is saying
After the last two weeks I've had I've considered starting a real-life sparks channel that shows some of the problems that never seem to occur on youtube. This mornings job was incredible. (new thread coming up). Messing around with camera's takes so much time though....!You've just explained in a few words what Del would still be trying to describe in 2 hours time. I think you should be doing the youtube videos!
A lot of these celeb Youtuber sparks employ a professional camera crew these daysAfter the last two weeks I've had I've considered starting a real-life sparks channel that shows some of the problems that never seem to occur on youtube.

Shows how much they much be raking it in then.A lot of these celeb Youtuber sparks employ a professional camera crew these days
builders and plumbers don't know the difference between their arses and their elbows. how to know expect them to know the difference between a RCD and a RCBO?We know the difference (I hope), but some DIYers / builders / plumbers don't.
