Pond Electrics, Electrician Removed Rdc

[Sidewinder]

You'd be happy installing 2 x RCD's in series - of the same value? on the same circuit?

Madness.

Not madness.

I do it regularly.

My client has responsibility for the ones we fit.

They don't have responsibility for the one upstream.

Thus they only have control of the testing for the one which they have responsibility for.

Thus in the event of one being required, then at least one will trip.

It's called redundancy, it is a valid engineering principle.

Why is it madness?

Would you take responsibility for a device which you have no control over, operating in the event it is needed to possibly save a life?

I am not able to reply with quotes as I havent made 10 posts yet, and I do need to reply to those who asked me questions.

The only way I could do it is to post as plain text. My replies are in bold, hope thats acceptable.

Unless it was a 75mm hole that the plug could be passed through 

No, its just large enough for the cable.

How many RCD's does your new CU have?

It has two.

Does your consumer unit just have ONE rcd for the complete house?

Ie. one off, ALL off?

Just curious

Off the top of my head they cover two circuits (upstairs and downstairs) I can dig out the specs for it if its important.

I wonder if you'll get a reply, he has the answer he wanted & is happy so fair play.

Although retired I still have to work self employed, I get up at 4.30am (always have) so I missed the last posts. I appreciate the many replies that you have all given me and have replied as soon as I could.

Although there isn`t a requirement for another RCD; I`d be happy with two - if/when one fails, you have a double redundancy scenario.

O/P - If the kitchen fitter / "professional electrician" altered this circuit; and presumably carried out other works - I hope you have been provided with the relevant certificates?

Having two did have its advantages, the RCD socket did trip once and the rest of the house wasnt affected (computers, server, wifes TV!) werent affected.

The builder uses a local electrical firm, he doesnt attempt electrics, we use him because of his profesionalism, value and trust him. Regarding certificates I expect they will come with the invoice, if not I will request it.

Thread title...

Electrician removed the "RDC"....

well thats all good then.....

as long as the RCD hasn't gone...

The RDC does f***-all..

Really sorry about that terrible typo, Im a computer engineer not an electrician, I didnt realise electricians required absolutely perfect spelling and grammar.

I get the feeling I dont belong here, but thanks to the others who helped me to ensure my electrics are safe and legal. Im tempted to reply in kind but as Im new here I wont.

Freebird,

Please stick around, some of our members are a little abrasive, but once you get to know them they have best intentions at heart.

Also, with the current state of the economy, may companies/tradespersons etc. are struggling for work, thus there may be a little reluctance to help persons with their DIY as ultimately, DIY reduces the work that is available for trades persons etc to obtain.

Surely you realise if you are a programmer that the correct command syntax is essential.

In engineering this is also true.

It is better to give the right information that way you get the right answers.

GIGO is a term I am pretty sure you will have heard.

I have unlocked the thread, as when you marked your last post as best answer and solved, it locks the thread against replies from others, I believe that this is not necessary at this time, unless you wish no further comment or discussions on your topic.

Thanks The Snake, apologies, I also suffer from the state of the economy, thats why Im retired and 67  but still working and up at 4.30am, I get a little tetchy.

I do give as much work as I can to tradesmen and I look after the good ones if I can, I have some horror stories (and I dont mean to upset anyone, but they were not from this country and really screwed my mums kitchen installation, nuff said), but I have regular chaps who I value highly.

GIGO is correct but in this case it was a typo, we all make them, doesnt make anyone stupid. Syntax is important for computers as they are basically stupid and follow instructions to the letter no matter what, humans should be a little smarter.

I will stay on here in case I need further profesional advice and hopefully I can help someone out myself, but I just hope SPECIAL LOCATION doesnt make a typo!

Just for the record although I do some programming I was a Systems Engineer, had a company Freebird Systems now closed and was contracted to work on Servers and Networks.

I understand now about the RCD and I am happy with the electricians work. I misunderstood the fixed installation thing in that it didnt legaly require a seperate RCD so he was ok removing it.

Thanks for everyone for taking the time to clarify things for me, its appreciated, and if I need an electrician in future maybe I can find a local one on here.

Thanks again

Phil

As long as the circuit is protected by a 30mA RCD a second one was unnecessary. I recommend duplicates to be removed when I come across them.

Oh dear....

Really sorry about that attempted humor injection error.. :|

Im a human not an robot or machine, I didnt realise that electricians were not allowed to try an inject a little humor onto the forum....

Perhaps I should just only reply with clear, accurate and factually correct posts in the future... :C

After a long day at work getting back home and browsing the forum some members, myself included do occasionally post slightly more light hearted posts onto a thread....

I do spend enough time posting clear answers to other questions... 

but the occasional less serious posts do still slip through... 

Sorry for replying wrong.

Personally I would rather have two RCDs in series and ONE of them trip on a fault, instead of having one RCD and it failing to trip resulting in my wife and family having half an hour out with the Vicar saying how wonderful I was!

Just ...not seeing a problem

 

[M107]

Freebird I wasn't having a dig about you replying, but we do fairly frequently ask/answer questions & hear no more from the poster who was asking for help.

It's nice to get some feed back that was all.

 

[apprentice87]

Murdoch,

Regarding RCD's and redundancy.. Do you disconnect the dual circuit brakes on your car too based on the principle that it is "more pipes to leak" As others have said, yes, it can be a right pain having two RCD's in series, but as long as it does not increase the chance of mishaps, it might just prevent a rather larger one..

I shall lighten up in future, thanks to you all.

Don,t lighten up too much.....some folks have lightened up so much on here that they are close to being "sectioned"!

OY!!!!!

You said you wouldn`t tell!!!!!!!!!!!!!!!!!!!!!
