Dangerous upgrade to crabtree rcbo's

[Alrebcon180]

Would be interesting to hear from Crabtree on this.

Contacted Their technical guys and he basically said they know they have voltage on it and have had other calls but their argument is that the fuse board should be switched off. Poor excuse if u ask me as their older models didn't have this problem.

I can confirm this, noticed it whilst changing a MCB for RCBO and definitely happens with the RCBO in the off position.

Oops.. Don't say u done it without turning the whole installation off.. U is gonna be in trouble.. Lol

At the very least its extremely poor design in my opinion.

Why design something that makes something more dangerous unless its necessary? Lucky I don't fit Electrium crap!

As I said I don't work in a domestic environment . Therefor your argument does not hold water

Don't Crabtree say these are for domestic use, that is most likely there get out clause for anyone trying to fit them with out isolating the incoming supply.

Anyone know someone who could look at these and tell us why this is happening.. I do find it strange that the wire covered in blue goes to the incoming live prong and the white covered wire goes to the neutral fly lead and then changes to blue..

I'm still not convinced by this concept that everything should be tickety boo for you, 'cos you've decided or your boss has decided for you, to work live on a piece of equipment. Fair play to you Alexander to highlighting the issue, but another reason for not to work live in the first place.

Presumably having made the decision made to work live, then you'll be wearing suitable PPE for the resulting bang not to matter a jot. I'm thinking big rubber gloves, full face mask, leather apron, rubber boots & replacement underwear.

My god your life must be full of exciting things..
I have a healthy respect for electricity but am not that scared of it that I sit up worrying all night that if I don't have my rubber pants on I might die everytime I open up a a single phase fuse board.. Do you really work as an installation electrician on site.. I guess not

Yeah I can look

Maybe this is why these devices are designed as such, to make life more exciting for those of you that like to spice things up a bit by ignoring basic safety procedures on a regular basis.
They've done you a favour. Imagine how boring it would be without things like this to keep you ticking over. Good job Crabtree !

My life's has been eventful, but I hope it goes on for a few more years yet, not least to keep getting my pension I paid for. I hope thats something you aspire to.

I've worked live a few times, did recently inadvertently; came as quite a shock.

However, there are very few times when it can be justified; if your honest with yourself. Often pressurised to do so by circumstances, but generally by others. I was taught many years ago, that no emergency, can ever justify a car accident. Same should be said for this.

Like with most things, the more you do something which can be construed as hazardous, it becomes the norm. When things become routine, thats when you most expose yourself to chance, like I found out recently.

Take care of your life, no one else is responsible for it.

I totally agree with that Midwest and you now just said exactly what I was trying to point out all along.. We do work live in circumstances and in these circumstances I was trying to stop someone getting a shock just like you did inadvertently.. But why do people then go all sanctimonious and say it should never be done.. You just admitted you got a shock on something u didn't realise was live which is more worrying than me working on something which I know is live as that points out that.you didn't test the circuit or carry out a locking off procedure to make sure it stayed dead.. ( lol I just became one of those people).. Normally I would have just said ---- mate you should be careful but I think this site is rubbing off on me

I know it was rather careless of me, got a zap off an electric fire.

Funny thing was I had isolated it, then my colleague said lets just see if it works, and I forgot to turn it off again. Oh how we laughed, well he did

WE can go on about live working, until the cows come home.
Simple fact is, an RCBO is a means of isolation.
This particular RCBO is not doing what it should be doing.
If I were to isolate the circuit protected by this RCBO to swap over a damaged socket front, the Neutral would be live as would every other Neutral connected to the Neutral bar.
