Yes todays job was a PIR on a private club. Unusually there was the previous PIR from 5 years ago, nicely written up on a Select PIR form and giving the install a clean bill of health. I confirmed with someone from the club that no work had been done since the last PIR so thought I was in for an easy day, and thought it would be interesting to compare my readings with the previous ones.
Well what an eye opener. for a start hardly any of the readings matched.
Then I got to DB No 2 that was labelled as having 4 socket circuits, and 2 lighting circuits. The last PIR also labelled them as 4 socket circuits.
But I could not identify which sockets they fed. ONE of them seemed to feed some sockets, but not the others. So I investigated. One fed an FCU right next to the DB, one fed the hand dryers in the ladies and gents toilets, and the last one fed a chiller unit in the cellar.
There's no way the previous sparks could have taken any actual readings without noticing these circuits didn't feed sockets, but did something else. So I marked up my EICR correctly and re labelled the DB. (remember I was assured there had been no work since the last PIR)
Then I found a socket circuit where the guy had recorded a ring continuity value. Shame was it was a radial socket circuit on a 20A MCB so can't have a ring continuity value.
Then he failed to notice the gas bond was only in 2.5mm, and at the wrong end of the gas pipe. That was ticked as "OK" and marked down as 10mm
And he failed to notice the N-E short on the Ban Marie circuit, N-E was marked as >199M ohm
And he failed to notice the two flexes exiting the control box for the fryer that had no bushes or grommets and were just rubbing against the sharp metal hole.
Nor did he notice the unknown circuit wired in 1mm t&e that had been tapped onto a 40A MCB serving a cooker. I disconnected that having failed to find what it feeds. When I get the "x y z isn't working" call, I will have found what it feeds and will re connect it on the correct rating MCB.
My guess is the guy took about 10 minutes to read off the labels on the DB's, have a quick look at the cable sizes and then went away to make up some values. He even got that bit wrong. One submain, wired in 6mm SWA using the SWA as the CPC, he had marked as 6mm for L and 4mm for CPC.
Totally shocking, first time I've seen a previous PIR so obviously made up.
