Good Old Delroy, he gets all the best Jobs :)

A few posts ago, I wrote that a RCBO contains an RCD, so yes, a RCBO is part of the family of devices containing a RCD.

You initially said that he does not have an RCD. I was just pointing out that he does. I kind of wish I hadn't bothered now.

It might have been down to how I read the comment, but I took it to mean a straightforward 500mA RCD wouldn't fully serve the intended purpose and that some form of overcurrent protection must also be incorporated.

My initial post on the subject was to query how a delayed RCD can provide overload protection. I then went on to suggest that it should be referred to as a RCBO, since these do provide both residual current and overload protection.
None of you seen an electric shower "protected" by a 40A 30mA RCD, straight off of a couple of Henlies? 40A 30mA RCBO, fine. 40A 30mA RCD, not fine.

I think we all know the difference. As I say, I was just being pedantic.

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

Disconnected a shower this week that was 'protected' by a 100mA RCCB directly from the tails.

Some even believe that a 80A switch somehow provides over current protection.

I have had plenty time served sparks tell me that a 100a main switch will trip under over load

I guess it is sort of true, if your overload is tens of kA!

Everything is a fuse if you go big enough

It does Pete.

They usually burn out before the tails

So is this device a time delayed RCD or RCD RCBO.

From the original description, it's a time delayed 4P RCBO

It doesn't look like any 4p rcd / rcbo that I've ever seen.

 

[Petej999]

RCD is the umbrella term for all types - RCCB, RCBO etc.

for the uneducated that is

Ok, not dear old Delroy....
I like Nick, and he's just kitting out this new space, but there's a slight distraction that I might have dealt with before making the video....!

Just watched a few minutes of his previous video and the tray isn't hanging down, but he does mention that it's all about to be ripped out.

Wish I hadn't watched it now as it was funnier being blisfully unaware of his plans
