to fail or not to fail

[its my opinion]

hi guys I'm testing a elderly peoples home I have all the correct readings on the ring mains however they are on a 32amp 60898 type b mcb should I grade as c2 or c3 or can it just be passed as satisfactory

 

[dan86]

whats Your opinion as the tester of what it should be?

 

[ChrisElectrical88]

That's not much info :-s is it on a board with a RCD? When were the electrics installed? Are there any special equipment connected such as blow up beds?

 

[its my opinion]

I have graded it as a C2 but i'm not sure that's why ive posted the thread to share opinions thanks Dan

 

[its my opinion]

hi spinks yes mate theres all sorts of equipment hospital type movement beds / Kitchens although all bonding in place in special locations etc. also 3phase board no rcd protection

 

[ChrisElectrical88]

I would possibly just make a comment about it if their is hospital beds plugged in etc. c3 at the most. What is your estimated age of installation?

May be I'm missing something here, but if you have all good readings applicable for the stated MCB why code it with anything?

Coding would depend on the use of sockets,if they might reasonably be expected to supply equipment outdoors for example, a C2 might be appropriate,otherwise a C3

Edit...I'm assuming the OP is concerned about RCD protection,as Murdoch states though,thats not made clear.

Well, I was wondering that but RCD's aren't mentioned in the OP!

 

[its my opinion]

hi the home and installation is 23 years all bonding in place as I said I graded c2 your opinion to change to c3

Like I said...depends on the expected use of the sockets

Why have you coded it? Is it lack of RCD's?

 

[its my opinion]

Hi Murdoch I was only coding it as I though that it does not comply to current regs as you rightly say everything has tested ok, there is no sockets used externally ie grounds maintenance etc back to the original post satisfactory or unsatisfactory ?

 

[ChrisElectrical88]

Can't give anything worse than a code 3 in my opinion if its just lacking RCD protection?

What you need to look at is what the socket is used for and its risks, elderly people home could have breathing machines dialysis machines etc ,you don't really want them on an RCD if you take into consideration the disconnection time 0.4 and Zs required to trip the protective device in that time , if the test result are within the required levels then no code if higher then there might be an underlying problem , you could code 3 it requires improvement , assess the level of risk really RCD's are for additional protection
