wouldnt it of been better to do the research prior to the change? or gain a working knowledge of the regulations?

and i agree that GStueyXR Must stop with his constant advertising campaing

Yes, it is always better to be prepared, and I thought I was. Of course one has to be open minded and be prepared to accept that one can lag behind the regulations. Being complacent is not an excuse for poor workmanship. But when you are dealing with Clients sometimes the best approach is one of compromise and let's be honest, if I do my work properly it will definitely be an enhancement.

So, there I was complacently sitting and reviewing the IEE regs when I hear this innocent comment, "The IEE regs dictate that at least 2 rcd's have to be fitted for a CU to comply..." Well blow me down with a feather but upon querying it it was confirmed (though no proof was offered)

Now, I'm not exactly wet behind the ears nor am I ignorant of the regulations so I wants to find out where in the regs I am out of touch. Sadly there is no such proof, only a 'necessary' adjunct ............

I think your biggest sin was letting a penny pinching client dictate how a installation should be done

 

[andekoch]

The regs make reference to mimimising nuisance tripping and circuit segregation as well as safety (not sure of the reg nos now as late). On that basis a min of 2 RCD's is sensible since imagine if it is dark and a lamp 'blows' and trips out all power so that the person in the kitchen cant see and spills hot oil over them selves while someone else trips and falls while lookign for a torch to find the CU and restore light etc etc.

Wouldn't one line of text linking to your website be enough Stuey???

Yes, but google loves lots of links to increase your sites ranking

Lol I think you spot on.

Mind you, the mamby pamby fuddy duddy wuzzyness of a certain publication didn't help ...

The BS7661 should take a leaf out of the cigarette packet ..... I mean to say, it likewise has all the 'warning labels' you can stick on the outside of the CU.

Why not go further:

Passive mcb's can be a danger to others

An rcd a way can keep the other's ok

how many times a year do you re-test your rcd? ...... quit the habit and die

here endeth the Sunday Sermon ..... those magic mushrooms are brill!

I dont see what the standard for 'Specification for inflatable armbands worn as flotation aids' has to do with this thread LOL.

e if it is dark and a lamp 'blows' and trips out all power so that the person in the kitchen cant see and spills hot oil over them selves while someone else trips and falls while lookign for a torch to find the CU and restore light etc etc.

See, this is what I don't get. If it's dark and your kitchen lights go out, what use are the kitchen sockets and upstairs lights being on?? the only way to stop people being in the dark is to have two lights in each room on seperate RCDs, or maybe have the lights wired so that the kitchen, hall, bedroom one, bedroom three are on RCD1, and dining room, living room, landing, bedoom 2 and bathroom are on another, which would be absolute lunacy!

 

[davelerave]

you could loop into a non-maintained bulkhead possibly

dunno if they have leakage

at least a few lighting rcbo's would minimize nuisance if you need 30ma protection

 

[stewart]

One day, there will be self-certifying CU's that will test and verify and self-test and even come with a handy remote control fob that will allow you wherever you be to reset that darn RCBO!

Naturally, each additional item of protection will come with a cost and the time will come whereby an improvement in safety will immediately be reflected in a set of Regulations that will be fluid rather than stagnant.

But, as things stand at the moment, if my customer can only afford a reduced level of electrical safety then I have to be aware of what is my bottom line of service. Maybe I have to choose between what they are prepared to pay against what I can offer and maybe I might have to quote for a lower standard but provide something that might reduce my profit but will be of a standard as would be expected by my peers ....

right then ..... single rcd it is lol
