RFC - no CPC continuity!

[Goody]

Hi,

I have just tested a RFC and the CPC was broken (no continuity). Tested all the socket on that circuits and R1+R2 was OK but I could't open a socket to check, as it was hidden (burried) behind a door frame and it must be a double socket with only one of its switches staring at me. To reach it, the door frame had to be sawed and the wall dug - not viable. What should I do in this situation?

I still haven't checked Zs on sockets.

Cheers!

take floor up?or multitool around edge of frame to expose socket.

Was R1+R2 the same at all the sockets

The landlord wouldn't allow anything being damaged.

Pretty much the same, not much deviation.

Derate the CPD, if they won't allow anything to be pulled apart easiest route. Typical landlord!

Eh?, if R1+R2 was OK on an RFC, how have you concluded that the CPC is not contiguous?

 

[Amp David]

Would of been apparent even before getting to the R1R2 test anyhow

 

[windtech]

did you test at that the cu once and did you use the croc clips because if you dont have the cable in right it can give bad readings

Checked CPC's continuity at the board and no continuity. Cross connected L&E and tested R1+R2 at the sockets.

You can't have got expected results for R1+R2 at the sockets in that case! Unless of course your expectation for R1+R2 was changed by the lack of an r2 continuous reading.

In that case the blocked socket must be roughly half way around the ring, does that stack up Goody?

Possibly yes, can't bet on it though!

Hmmm, in that case not sure I'd want to cut the door lining ... unless I could be pretty sure that's where the fault was. Is it a standard size door lining (ie easily replaced)?

If you do need to cut it, cut it at an angle (ie not parallel to the floor), it's easier to get it to sit right when replaced if you do that.

I'd suggest trying to prove that's where the cpc break is before entertaining any cutting . Try a wander lead check around both halves of the ring to prove that's where the break is.

This is what I was talking about and what an idiot he must be, whoever did it!

I don't see what choice you have but to expose it I certainly wouldn't be putting my name to it without doing so!
