100ms time delay rcd on main domestic unit?g

[Des 56]

He has not described the installation
He has not outlined what has been highlighted by the inspector
Yet He wants to know if the consequences of an inspection are correct

Replies have asked for this sort of information whilst giving general views on Rcd protection,why so ?


He either supplies this information or this thread is a complete waste of all your time
:waving:

high impedance on 25 on circuits 2 and 3
unable to locate cooker circuit
unable to locate water bond -no continuity to earth
100 ma TD main switch
unable to locate heating circuit
wrong size mcb on cooker circuit 40A
wrong size mcb on shower circuit with 6mm cable 50A

all these have code c2

im a bit annoyed since..
we no longer have an electric shower it runs off the combi boiler,
we have a gas hob, and the fan oven is rated low enoug for the kitchen ring,
the cooker circuit serves nothing

Unable to locate cooker circuit but it's on an incorrectly rated MCB?
I'm at a loss to understand why he would code an S type RCD as a C2
What does "high impedance on 25" mean?

 

[GLENNSPARK]

there is a 30mA Rcd half way down the bus
would this setup be acceptable for eicar or unsatisfactory?
also, there are two breakers which are lableled cooker and central heating, these are unused the wires go nowhere, , its lagacy of old house, cooker and ch are on kitchen ring now
should it fail eicar for this?
ta

you say the `wires go noware`...if so...have these cables been taken out of the terminations at the board?

Maybe high impedance on ZS.

> high impedance on 25 on circuits 2 and 3
should show on the test schedule what the Zs is for those circuits. that, against the mcb ratings will say what the problem is.

>unable to locate cooker circuit
reasonable if there are actually cables going to it. easy enough to fix by disconnecting..

>unable to locate water bond -no continuity to earth
so he is saying it didn't measure out properly?

>100 ma TD main switch
based on that info - no fault....

>unable to locate heating circuit
as cooker

> wrong size mcb on cooker circuit 40A
> wrong size mcb on shower circuit with 6mm cable 50A
disconnected there would be no problem

I have to admit that most of this would have been easily sorted by disconnecting the unused circuits at the time the inspection was done......

But puzzled by first point - can you email him and ask for an explanation? On the schedule of test reults what are the readings for the Zs for these circuits???
I thought you said in your other thread he'd installed bonding to the water.
100 Ma TD main switch - not sure that's a code at all
Rest could be C2's but they are hardly costly to put right and yes the "unable to locate" circuits is harsh but correct

You asked for a EICR, so do you expect a "satisfactory" if there are issues?

Your footnote is largely irrelevent, imho

 

[CDM]

If there are two unknown circuits,I would advise that they should be isolated.Cables removed from the consumer unit and your cert will come out clean.

 

[Steve_P]

Damn it you lot can type faster than me.

Ok so bonding needs to be confirmed but by the sounds of that, most of it shouldn't take long to sort. Is the sparky really an spark? Sounds like some bloke from the pub or a Electrical Trainee just out of day release.

high impedance on 25 on circuits 2 and 3 - can't comment on this, what are these circuits? What are the results?
unable to locate cooker circuit - so disconnect it.
unable to locate water bond -no continuity to earth - that should be sorted . . . . .
100 ma TD main switch - again, doesn't mean a lot as a statement on its own.
unable to locate heating circuit - do you have heaters / a heating system? If not, dosconnect it.
wrong size mcb on cooker circuit 40A - this is the circuit that he can't locate then?
wrong size mcb on shower circuit with 6mm cable 50A - ok, the breaker is OTT so why can't the shower go into the breaker that the cooker isn't on? Depends on the shower of course but seems obvious.

we no longer have an electric shower it runs off the combi boiler, - This is probably cheaper than the electric shower, it's what I've got.
we have a gas hob, and the fan oven is rated low enoug for the kitchen ring, - what is the rating of the hob?



Without seeing the installation and the certificate and probably some photo's it's difficult to comment really. If this guy is actually an electrician there will almost certainly be a reasoning behind what has been said. Is there something that we're not being told?

 

[trev]

Maybe high impedance on ZS.

Aye, could be mate

 

[Guest55]

sounds to me as if the OP just doesnt like the verdict on his inspection - end of.

were just going round the houses here to be honest , none of us on the forum can change what your electricican has reported so just pay up for the repairs if you want a pass cert.
and fiddling with telecoms dont mean jacks**t in our world lol.
;-)

 

[cmp260]

sorry what is Zs? you could be right ive read it wrong as 25

i hired this company off mybuilder.com, for a landlord cert, eicr. they were cheapest quote, but im getting the distinct feeling they are trying to pad it out.
i actually said to the bloke when he was here sucking his teeth, why cant the mcb for non existant cooker and shower just be disconected and if any wires going to them, cut them well back. apparrently he was happier just to fail it...

im still unclear on the watermain earth though, do you have to absolutely see the connection on the water main within ?? mm of the stopcock to "pass "?

i have to say thoughi realy apprciate all the advice and no, im not going to peru

 

[PEG]

Come on Biff,don't sit on the fence....tell it like it is....:28:

 

[cmp260]

love you too biffo, the OP is happy to pay for work due, but gets a bit ****y with "cute" trademen -thats cute in the irish sense. i.e not sexy
thanks the rest of you. if you want advice on a pbx happy to help.

Oh dear!!

 

[trev]

i hired this company off mybuilder.com

Oh dear! Not everyone on there is bad though. The earth bonds are supposed to be visible and accessible.
To be fair to the guy though he was there to report on the installation not carry out any necessary rectification

 

[cmp260]

yes, i know

I think you have just found out why cheap isn't always cheap ;(

No, you don't need to see the water earth the pass it. Or I wouldn't anyway - I'd say a C3 if I testing ok.
If you don't like what they have said you can always get someone else to fix the faults. If you get a cert from another spark saying all the faults on the original EICR are fixed then I believe you are good to go.....

EDIT: of course you would have to find a spark who is happy to approve the bonding by testing it and inspecting one end only. Some won't, as shown by comments here.....

 

[cmp260]

seems strange there is no hard and fast rule on the water earth, one persons c2 is anothers c3.. can this be right?

 

[Steve_P]

landlord cert, eicr.

???

Isn't the landlord responsible for all this? If you are the landlord then I'd say pay for the EICR, you know there's some issues that need to be sorted, move on from that and and get some quotes on the remedials, including the company you've already used.

im still unclear on the watermain earth though, do you have to absolutely see the connection on the water main within ?? mm of the stopcock to "pass "?

Need to be able to locate it, at least point to the cable/clamp and say "THAR SHE BLOWS!", confirming that it's connected isn't really enough and in this case it sounds like it isn't connected.
