Re: PAT testing network switches
Point of Interest.
When I was a Electrical Apprentice (a long time before the PAT tester ) you used a 'megger', we used a 5000 volt one to do some tests and as apprentices you bet your mates how long you could hold the leads and turn the handle (I know now why I have no brain) it made you eyes light up !!!.
I still have one of the older ones of my fathers from the second world war and it still works, its got a handle on it you turned to generate the voltage to do the test and a meter scale on the top which is calibrated in meg ohms.
After them you had the battery powered 'megger' .

Fully agree with what could happen to a PC with 500Vdc to a PC but any PAT tester worth his salt will test all full voltage PC's.... having said that though if you are only testing the IEC lead then you are not fully ensuring the equipment has a correct earth bond, this should be an instant fail for a class 1 PC as you have only carried out half the test. Dependent on the PAT tester used, there should be the facility to reduce the current to 100mA for Class 1 IT Equipment, my Seaward has inbuilt preset tests which include the 100mA drop and has never popped a PC yet.
