On a domestic EICR

Wobbly camerawork abounds in this video filmed ad-hoc during an Electrical Installation Condition Report performed on a domestic TT installation recorded on 27th August 2019. This is our first visit to this site, so familiarisation was required on this Victorian property whch has an extension built in the past forty years. The CU had been replaced by the previous owner as an apparent DIY job... well, at least I hope that's what it was and he hadn't paid for the cack-handedness. Still on the wall was the old 100mA RCD for fault protection, no longer needed now that all circuits are RCD protected in an insulated consumer unit as the RCD's provide disconnection of supply in the prescribed time seeing as the MCB's can't be guaranteed to because of the high Ze.

The installation was deemed as 'unsatisfactory' on the report. Various remedials are required including sorting the Class I garage lights that are unearthed. Also, r2 was slightly high on both socket rings and one lighting circuit reported IR of only around 4 MegaOhm, but poor junctions were observed where lighting has been modified. I'd like to see a second earth spike installed to try and lower that Ze a little. There were some other issues not shown here.

Western Power Distribution were called out on the day after we found a hole in the service head. Sterling service from them as always, they were there just a couple of hours later.

The laptop we use for Easycert is a refurbished Lenovo T430 available from Amazon on this affiliate link: https://amzn.to/2Lephpa - this one has a 3G modem card installed for no-hassle internet access on the go.

Despite the low battery in the camera, we had a lot of footage recorded on the day and about 25 minutes has been cut from this video to keep it at some kind of sensible length. Most of the cut footage was our form filling on Easycert, but that really deserves a video of its own rather than being shoehorned into this one. We show here one ring end-to-end, r1+r2 and IR testing, plus some testing on a lighting circuit, but r1+rn testing, RCD testing, Zs testing and the testing of most circuits is omitted from this video to prevent it being longer than the director's cut of Ben Hur.

The consumer unit is still untidy, but screws have been tightened, wires re-terminated and circuits placed into the correct terminals. The untraced circuit was pointed out to the homeowner and left switched off to allow them to spot if anything wasn't working that we may have missed.
