Smart Board Projectors

He's asking about leakage not touch current, unless I'm mistaken they are different.

Since leakage to earth is not really covered in in service testing and he is using a PAT tester I would assume he is measuring the protective conductor current or touch current in accordance with the COP. which is the current that does leak to earthed parts.

In answer to the original question, there is not really any "get out clause". I would just say make sure you are testing correctly and see if you get different values, it is a bit of a pass fail situation for in service testing. But 3.5mA does seem a bit high for a smart board projector, they may be just a cheap power supply.

I could have sworn our Portable appliance tester measured leakage current aswell as touch currents.

Thanks for the great response to my main question, so the conclusion we all seem to agree is the projectors for the smart boards maybe, failing due to the readings given.

3.5 is a fail for class I equipment and no exceptions (not counting Heaters 3.5/5mA).

I like the idea of a bad power supply, this guides me to a reason, the tests where constant, as I tested 3 times and the readings did not change on three accounts.

Tester was a Martindale 2100.

Thanks again for the good advice..
