Many system owners have probably seen changes in the performance of their systems between spring and summer. The days are longer and the sun is higher in the sky but it's also warmer and the sky is a bit hazier.
I have been able to collect various pieces of data on my system and have graphed...
I was just wondering what results I should be expecting to see in all of my dead and live tests. If someone could help me with a list or something it'd be much appreciated.

Hi,
I'm doing a CU change in a couple of weeks and the customer (a retired engineer) has asked if I will be supplying "N Test results for main circuits
supplying this consumer unit."
Does anyone know what he means by this?
Thanks.
I'm rather new to testing and interpreting results. Did a test two weeks ago on a new ring installed then with continuity results L-L 0.37, N-N 0.36, E-E 0.60 and L- E 0.25. All good. Tested it today and got results L-L 0.17, N-N 0.17, E-E 0.39, L-E 0.05. Not good. I'm testing it again tomorrow...

Hi all, after considering replacing a friends old part rcd protected CU for a Wylex Hi Integrity unit, I have found the ring main to be the only ring in the house. The Continuity readings are R1 = 1.03, RN = 1.03, R2 = 1.87, these readings appear to me to be perfectly acceptable for the size of...
Hi Guys a little bit of help needed. I work on the border between England and Wales
In a recent test result I get results of 30 on the Welsh side and 3 on the English side.

Hi Guys,
Have seen some similar threads on these boards but still after some wisdom . . .

Hi Guys,
I have been testing for about a year and have come across my first tt system yesterday.
I disconnected the earth and tested for Ze and got 8.67 ohms which I believe to be a great reading as osg allows up to 200 ohms. I couldn't do a Ra reading as the rod is under the house and...
