PAT testing question

[owen10]

Hi

One of my work mates recently done some pat testing at a local doctors , the pat tester we have is a seaward one which you just plug the equipment in and it lights up pass/fail. no reading etc

the items he had fail were 2 4way leads but were surge protection ones , has anyone come across this ?

also the had 19 label printers, the all had leads like you have with a laptop . 13 failed but 6 passed. all look fairly newish.

does anyone else think this is a bit strange

what did they fail on? IR or cpc continuity ???

IR

surge protector leads have a low IR between live/neutral and earth.

really need more details of why they failed, and did he actually put a fail sticker on them? if he did, and it was simply because of low IR by design, then i would say he is not competent to do such testing.

there is more to PA testing than simply plugging it into a tester

I did a school last week and if I had failed everything my PAT tester had told me to. there wouldn't have been a lot that passed.

As Andy says, it's how you interpret the results on the screen. A lot of IT equipment will be over the 0.1ohm parameter set at the factory, when testing earth bond,thus showing up as a fail on a lot of testers, purely due to the length of the lead, which you must take into consideration.
