EICR Many many faults

[Brightspark2]

Hi,

I conducted an EICR last week on a three bed property with a large extension.

• Broken earth on two lights downsatirs
• No ZS readings possible on the upstairs lighting circuit at any of the accessories. Switch drops wired in twin red no earth.
• Ring main no continuity >2000 ohms on all conductors
• Ring main 0.03 N-E 0.13 L-E 6.6 L-N IR readings
• 80 volts on switch wires of two seperate circuits
• 70 volts on ring earth

If you can't get a Zs at any accessories is there a CPC in this circuit?...all acc are plastic...

Ring main could actually be radials or 1 radial with a spur from the CU...

False reading??? Is there a load possibly still connected?...

Last 2 as mentioned could be induced voltage...

Hi Mike,

sorry looking back at the original post I can see its a bit of a hash! The two outcomes I was hoping to she'd some light on were fault finding on a ring main and the reading of 80 volts on the switch wire.

i have changed the consumer unit for a dual rcd board, upgraded the gas/water and main earth and am hoping to find the break in the upstairs lighting cpc. As you say a sticker will have to be stuck on the board as the switch drops have no cpc. All of the accessories are plastic.

The 80volts on the switch wire is baffling me and I can't think how that would happen.

i guess the only thing I can do is strip it down and test conductors end to end to investigate?

I think the advice by the guys above concerning induced voltage is probable, at worse you will have to get your tester back out.

Hi Glenn, what is this forum for if not to talk to other electricians and share experience?

Have you ever felt that an extra opinion or exchange of views may help you to a wiser decision?


what would any forum be if not for the sharing of advice. If everyone had the same opinion as the one you have just expresses then there would be no forum, just a gathering of people who every time a question was asked felt they needed to throw it out due to the posters unworthiness!!!

ha ha ha!!!

listen ...
dont try ostracising me on here fella....
what i said still stands.....if you are carrying out ECRs then you would at least expect how to go about no end to end values on a ring final if it is that...and no CPCs on lighting circuits etc...
i mean come on...

As you say in post 24...


There could be no problems at all here...
