Some Professional Advice Required

7200 doesnt sound right. maybe +200?

either way, either he hasnt done the test, or the fixed wiring isOK from that part and the problem is somehting you have plugged in. even plugged in is enough, it doesnt actually have to be on to cause a problem

 

[Sharpend]

Could it be a mis placed busbar? Or incorrectly terminated into the rcd, not in the terminal but behind it?

 

[ProDave]

dont want compo just want a conclusion and peace of mind and whats happened is why I would rather go another route .

The most expedient route in that case is to employ another local electrician to do a PIR (periodic inspection) on the work done and after inspecting and testing it, he will give you an EICR (Electrical Installation Condition Report) which will tell you what is right and what is wrong and recommend any work needed to put things right.

got 3 sheets of NA/EC/001 (V1) - sheet 3 right? its a bit scrawly but does 7200 seem right? its that value for both cooker & ring for live/live & Live/earth

Those initials mean nothing to me (anyone else) but if "7200" is a figure for insulation resistance then no it does NOT sound right. What is the PRECICE heading of the column for that figure?

ok Andy , but does this unit not actually "trip" off? and any ideas why I am also losing the rest of the ground floor when it does go off as thats not on this RCCB ring?

I agree, had a customer with cooker working one then not the next, that was a shed install though

 

[Andy™]

there s probably more than 1 circuit on the RCD, so a fault on one thats trips RCD will cut power to another circuit

As I see it you have 2 options, anything else just clouds the issue:

1. Get them back to sort the problem. As long as it is a fault of the work they have done it should cost you nothing.

2. Get a different electrician in, but the costs would be born by you.

You cannot get someone else in and expect them to foot the bill.

From what I'm reading it's not tripping the rcd?

As I asked in post #5 (and you have not answered)

WHAT goes off?

you also mentioned things going off, then coming back on WITHOUT you resetting anything.

So it has all the hallmarks of a loose connection. Quite possibly as already mentioned, a busbar finger has "missed" the cage clamp and so is making poor intermittent contact somewhere.

 

[steptoe]

right,

somebody else read back through this, cos Im sure someone has already said a bad connection, or Neutral somewhere,

sharpie has said it again,

and for me an intermittent fault like this would be very reminisscent of that type of fault,

extra CU installed and a cable on the wrong side of a cage.

could it be a "T" ?

as above, it may have been Dave that mentioned it earlier,

my thoughts exactly

Sorry , bear with me , when it goes off the NEW kitchen ring AND NEW cooker both go off ALSO the remainder of the ground floor power ring which is on a 30 A fuse - power comes back the RCCB is not tripped and doesnt have to be reset and the fuse in the 30 A isnt blown.

sorry I missed that - apologies

 

[Sharpend]

So you have said that you believe the new board and circuits have been fed from the ring circuit, is this the downstairs ring? If so we deduce that a poor termination is the culprit. This would be at the old fuse, at a guess you understand not having seen either!

 

[lensman]

sorry red dotted fuse - thats 15 is it not?

 

[Sharpend]

Red is 30amp blue 15amp.

That cert, is it a Napit cert?

no it was a snippet of info told to me when he was telling me what they were doing - but while not a guess I may have misunderstood.

yes , the number I quoted was the stationary code bottom right
