for the uneducated that is

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

Also according to definitions given by the IET, and the manufacturers organisation BEAMA, and every training course I've been on over the last few years.

Just Googled RCD. Loads of definitions, all explaining, in language ranging from simplistic to technical, how it protects against earth leakage faults, either direct to earth or through a person, but not one that mentions overload protection

Try BS7671 definitions.

I am no mathematician, but...could someone clever draw a Venn diagram showing the relationship between MCB/RCD/RCBO/every other protective device...then i could print it off and colour it in!

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!
Palin would eventually appear in that costume and start to say he uses not two or three but four kinds of aftershave: frankincense, myrrh, sandalwood... and I'd nearly choke into my party 7. Happy days eh!
Oh did we forget the nice red uniforms? Or did I make that up?!

Not heard that for a long time - thanks! Time for a new profile pic I think....

westward10 · Jul 22, 2022

My mother still has a Watneys red barrel key ring on her keys.

adonis2 · Jul 22, 2022

Anyone remember Watney's strong pale ale, used to love downing a few of them.

As we are taking a trip down memory lane , here is Del's first ever vid

impish15 · Jul 26, 2022

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

Keep the questions coming - it's what this place is here for!
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.

Dustydazzler · Jul 26, 2022

Srtaggering the Ring / Starring the ring as I have also heard it explained is a really old Skool method that I was shown when I was about 15 on site. The old guys who wire a ring odds and evens point 1-5 , 2-6 , 3-7 , 4-8. They said it would balance the load...
I never do it this way but some pople used to do

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!

It's good that Del after 40 odd years is still learning.

Why does two shorts planks come to mind

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....!

A lot of these celeb Youtuber sparks employ a professional camera crew these days

Shows how much they much be raking it in then.
I wouldn't want to be in that world, dropping brand names in return for sponsorship every 30 seconds and having to worry about making a video as well as finishing a job. I bet occasionally these are in conflict and the video wins.
On the other hand I might do a few simple youtube shorts. We'll see.

We know the difference (I hope), but some DIYers / builders / plumbers don't.

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?
