If you are getting 0.00 ohms on all the end to end continuity readings you really need to be looking a little harder as something is not right especially how you have discribed the FRC.

Did you try taking the readings at a socket outlet?

What was you R1 + R2 for the ring cct ? What was the ZS for the cct ?

That's cheeky...

I would code both C2 due to the fact that they are in Zone 2 and not IPX4 or better IMO.

What is the IP rating of the towel rail?

Hi all,
Strima, The bathroom lights are normal mains gu10 lamps and arnt directly over the shower but could defenatly have contact with stram and moisture.

Strima & jud, brucelee, mogga the end to end was belling out ok as that was one of the first things i checked with my fluke t5's it was belling on line to line, eathr to earth and neutral to neutral i also belled out every wire against every wire to check for cross connections and it all was fine. Then when i put my actull testers fluke mft 1653 on i got a result of 0.00 on all the wires. The circuit is the hole house ring 13 sockets in total, not insludeing the kitchen ring on a diffrent mcb. also the earth was two seprate wires and i pulled a bit of the slack down and checked and re sleved.

The house was wired to the 16th edition at a gess as there was a huge rccd device in line on the main tails. The wires were solid copper but black and red in colour and by how low the insulation resistance is id say comeing very close to the end of its life so 20 - 25 years?

Still can't see 0.00 or 0.01 for number of sockets, are you sure you didn't have meter set to Mohms? Sorry if that sounds condescending but we have all done it!

Cant see why pvc/pvc cant go on almost indefinitely, i would say any poor IR readings are usually at sockets. I bet if you took all the sockets off, put chock blocks on, your IR readings would get up to the 100 Mohms sort of reading.

That's what the meter said. Even broke the ring to check and used my confidence box on the meter, all checked out. Meter was calibrated last week and came back with no problems. Each socket test was a little different due to the metal conduit being the CPC.

All test on the circuits were excellent considering they were installed in 1955. Something to be said for imperial stranded cables.

FCU - code 2
Cable outlet - code 3 (if that) recommend changing it to a outlet plate where the cable exits vertically downwards

2nd off sorry for the typo i was ment to say contunity. I was reading on gn3 and wrote what i was reading by mistake. The result was comeing back 0.00


If your meter has just been calibrated etc then I would imagine you may have accidently zeroed the meter during your first reading. That said, you still would have got a different reading for R2 (earth).

No way that you would get 0.00 ohms on a RFC. Has to be a short somewhere.
