PAT by X-Ray connection?

AncientMariner
My wife owns a house which is let out through a Letting Agent. As such they manage the property and my wife gets the bills.

A few days ago the Letting Agent's contractor carried out a PAT. This for the Fridge, Freezer, Dishwasher and an Electric Fire - these all part of the property.

However her tenant manages a company where they have PATs carried out every day and thus familiar with the process. She spotted that all they did was to ask if any problems and write out the four labels!

He did have a tester with him, from the emailed test sheet a Seaward Apollo 400. But none of the appliances were plugged into the tester - the mains plugs having their respective sockets in cupboards.

So must have been an X-Ray connection……..?

    I was in an office some years ago when the "PAT" team were there. Usual situations for an IT office - lots of daisy chained 4-way extension leads feeding PCs/monitors etc on desks (so potentially quite high protective conductor currents). I was curious that they seemed to be able to test each extension lead by just disconnecting it from supply & loads and then plugging it into a little tester. That's interesting said I - how do you check the earth continuity from just one end? Bloke said the test box does it - and shows me his smart little tester and pokes a few buttons to list the tests on it's little screen.  As far as I could tell it was just doing an IR test, but not a polarity nor earth continuity. So the box bleeped OK, and they stuck a green sticker on it.


    I did raise it with the office management, but their attitude was basically 'we don't understand they technicalities, they're the professionals, so we have to leave it to them' i.e. they've got their bit of paper, box ticked, so think they're discharged their responsibility.


    If I'm ever in the situation of knowing in advance that PAT like that is going to happen, I'll have specially 'modified' extension lead to hand and see if they spot the faults. If (when) not, I'll have something concrete to berate management with.
