No continuity on cooker circuit.

[Iona222]

Not getting a continuity reading on the cooker circuit. I'm doing I.r. test and its low between l. N. Any ideas what the issue could be.

The cooker sockets is working also.

Neon on switch between L and N?
also, what continuity test are you doing?

I'm doing a low ohnms continuity test. I'm
Getting a reading live to neutral.
Nothing live to earth.

What reading are you getting. You will only get a line to cpc reading if you have connected a link across them.

 

[DPG]

Could you clarify exactly what test you are doing and exactly where you are measuring between.

Your OP mentions two completely different tests.

What exactly do you mean by not getting a continuity reading? how low was the IR Test? cooker sockets is working also?

 

[westward10]

Dont want batter you with too many questions but as above can you clarify. Insulation resistance test at 500v or continuity test.

I have mate. I'm not getting a reading. When I link line and neutral I get 0.10 ohms

So there must be a break in either the live or the earth. Now, along with the line-to-neutral being OK, you say the socket is working so those may be a clue.

I bet Zs is poor. Although obviously dead tests should be sorted first.

 

[westward10]

This is a matter of deduction, three conductors and two linked are fine but the third when linked is not so what does this tell you.

 

[Iona222]

Zs for the installion is OK. But everything fine apart from no continuity on the line earth at cooker. Obviously if there's a fault the breaker might to work

Sound mate.

Zs won't be fine on the cooker circuit I bet.

So, what is the next step you will make?

So the means of fault protection wouldn't function then. Additional protection might. But issue needs solving.

Test cont between LN LE NE IR the same and publish the results,

 

[westward10]

If this is an initial verification do not energise the circuit for a Zs until this is resolved.

Ah - as he said it was 'working' I assumed it wasn't initial which may have been the wrong conclusion.

Are you linking out at the CU and then testing at the cooker isolator or the connector plate lower down? Make sure you are breaking it down correctly. Test just the feed cable (unless that's what your having issues with...) then just the cable from the switch to the connector plate. This will rule out bad connections.

If you are testing with the switch inline and it's not been used before (brand new) make sure you rule out a faulty accessory

Tell the client the have a fault. They need to get fixed. I'm just doing the eicr. I'm rubbish at fault finding mate.

Ah sorry. You've got a trainee badge on your status so assumed you were still learning. Obviously wouldn't be doing EICRs if you were. Be worth getting the mods to remove that if that's the case.

Fear not it does get easier.
If it's an EICR I'd probably have started with a Zs test using the socket on the cooker plate. In under a minute you'd know you have a CPC issue, either broken or termination issue.
